# Manual del Gestor d'arxius

## Introducció

Podeu utilitzar l'aplicació Gestor d'arxius per crear, visualitzar, modificar o desempaquetar un arxiu. Un arxiu és un fitxer que actua com a contenidor per a altres fitxers. Un arxiu pot contenir molts fitxers, carpetes i subcarpetes, generalment en forma comprimida.

El Gestor d'arxius només proporciona una interfície gràfica, i es basa en utilitats de línia d'ordres com ara `tar`, `gzip` i `bzip2` per a les operacions d'arxiu.

Si teniu instal·lades les eines de línia d'ordres adequades al vostre sistema, el Gestor d'arxius admet els formats d'arxiu que es llisten a la taula següent.

Format | Extensió de fitxer
7-zip archive | `.7z`
ACE archive | `.ace`
Alzip archive | `.alz`
AR archive | `.ar`
Arxiu ARJ | `.arj`
Microsoft Cabinet archive | `.cab`
Arxiu CPIO | `.cpio`
Paquet Debian | `.deb`
raw CD image | `.iso`
Arxiu Java | `.jar`
Enterprise Application aRchive | `.ear`
Web Application Resource or Web application ARchive | `.war`
Arxiu LHA | `.lha`, `.lzh`
Roshal ARchive | `.rar`
Comic Book (Rar-compressed) | `.cbr`
Paquet RPM | `.rpm`
Arxiu ar | `.tar`
Arxiu tar comprimit amb `bzip` | `.tar.bz` o `.tbz`
Arxiu tar comprimit amb `bzip2` | `.tar.bz2` o `.tbz2`
Arxiu tar comprimit amb `gzip` | `.tar.gz` o `.tgz`
Arxiu tar comprimit amb `lzip` | `.tar.lz` o `.tlz`
Arxiu tar comprimit amb `lzop` | `.tar.lzo` o `.tzo`
Arxiu tar comprimit amb `compress` | `.tar.Z` o `.taz`
Arxiu tar comprimit amb `7zip` | `.tar.7z`
StuffIt archive | `.bin` o `.sit`
Arxiu zip | `.zip`
Comic Book (Zip-compressed) | `.cbz`
Arxiu zoo | `.zoo`

El format d'arxiu més comú en sistemes Linux i similars a Unix, és el fitxer tar comprimit amb `gzip` o `bzip2`.

El format d'arxiu més comú en sistemes Microsoft Windows és l'arxiu creat amb PKZIP o WinZip.

### Fitxers comprimits sense arxivar

Un fitxer comprimit sense arxivar és un fitxer que es crea quan utilitzeu `bzip2`, `gzip`, `lzip`, `lzop`, `compress` o `rzip` per comprimir un fitxer sense arxivar. Per exemple, `fitxer.txt.gz` es crea quan utilitzeu `gzip` per comprimir `fitxer.txt`.

Podeu utilitzar el Gestor d'arxius per crear, obrir i extreure un fitxer comprimit sense arxivar.

El patró pot incloure símbols de comodins estàndards com ara * per coincidir amb qualsevol cadena, i ? per coincidir amb un únic símbol. Podeu introduir diversos patrons separats per punts i comes. El Gestor d'arxius aplica l'acció a tots els fitxers que coincideixin amb almenys un dels patrons. Els exemples de la taula següent mostren com utilitzar els patrons de nom de fitxer per seleccionar fitxers.

Patró | Fitxers coincidents
`*` | Tots els fitxers
`*.tar*` | Tots els fitxers amb extensió `tar`, incloent-hi aquells en què l'extensió `tar` la segueix qualsevol seqüència de símbols, com ara `nom_fitxer.tar.gz`
`*.jpg; *.jpeg` | Tots els fitxers amb extensió `jpg` i tots els fitxers amb extensió `jpeg`
`fitxer?.gz` | Tots els fitxers amb extensió `gz` que tenen el nom «fitxer» seguit per un caràcter qualsevol, p. ex. `fitxer2.gz`, `fitxerx.gz`.

### Com obrir un arxiu

6. Feu clic a Desa.

   Si tots els fitxers en l'arxiu estan protegits per una contrasenya i no l'heu especificat, el Gestor d'arxius us demana que introduïu la contrasenya.

   If some but not all of the files in the archive are protected by a password, and you have not specified the password, Archive Manager does not ask for a password. However, Archive Manager copies only the unprotected files to the new archive.

   Per obtenir més informació sobre contrasenyes, consulteu engrampa-encrypt-files.

## Modificar el contingut d'un arxiu

You can modify the contents of an archive in several ways.

### Com xifrar fitxers en un arxiu

For security, you might want to encrypt the files that you add to an archive.

If the archive format supports encryption, you can specify a password to encrypt the files that you add to the archive.

Currently, only 7-Zip, ZIP, RAR and ARJ archives support encryption.

To specify a password for file encryption, perform the following steps:

1. Choose Edit Password to display the Password dialog.

2. Enter the password in the Password text box.

3. Feu clic a D'acord.

Archive Manager uses the password to encrypt the files that you add to the current archive, and to decrypt the files that you extract from the current archive. Archive Manager deletes the password when you close the archive.

For information on how to check whether an archive contains encrypted files, see engrampa-extra-info.

The encryption provided by archive utilities is weak and insecure. If security is important, use a strong encryption tool such as GNU Privacy Guard.

### Com reanomenar un fitxer en un arxiu

To rename a file in an archive, perform the following steps:

1. Select the file that you want to rename.

2. Choose Edit Rename, or press F2, to display the Rename dialog.

- Feu clic a D'acord.

### Com modificar un fitxer en un arxiu

To modify a file in an archive perform the following steps:

1. Double-click the file that you want to open. Alternatively right-click the file and choose Open.

2. Edit the file opened in step 1, and then save your changes.

3. Archive Manager shows a confirmation dialog, asking confirmation to update the file in the archive with the changes you made.

4. Click on Update.

Archive Manager uses the system-defined associations between file types and programs to determine the appropriate application to launch for a specific file. These assocations can be displayed and modified in the Open With tab of the file properties dialog. If Archive Manager cannot determine the appropriate application, Archive Manager displays the Open Files dialog to let you choose an application, as described in below.

#### Com modificar un fitxer en un arxiu amb una aplicació personalitzada

You can use an application specified by you, rather than the default application, to modify a file. To use an external application to open a file:

1. Right click the file.

## Viewing Archives

Archive Manager enables you to view several aspects of an archive.

### To View the Properties of an Archive

To view the properties of an archive, choose Archive Properties to display the Properties dialog. The Properties dialog displays the following information about the archive:

Name

- The name of the archive.

Location

- The position of the archive in the file system.

Modified on

- The date and time at which the archive was last modified.

Archive size

- The size of the archive contents when compressed.

Content size

- The size of the archive contents when uncompressed. This information is also available in the statusbar.

Compression ratio

- The compression ratio is a value used to describe the reduction in size of the data. For example a compression ratio of 5 means that the compressed archive is 1/5th the size of the original data.

Number of files

- The number of files in the archive.

### To View the Contents of an Archive

Archive Manager displays the archive contents in the main window as a file list with the following columns:

Name

- The name of a file or folder in the archive.

Size

- The size of the file when the file is extracted from the archive. For a folder, the Size field is blank. For information on how to display the size of the compressed file, see engrampa-extra-info.

Type

- The type of the file. For a folder, the value in the Type field is `Folder`.

Date modified

- The date on which the file was last modified. For a folder, the Date modified field is blank.

Location

- The path to the file within the archive. This column is visible only when the window is in file view, when in folder view the location of the files is displayed in the Location text box of the folderbar. For more information about view types see engrampa-view-type-folder.

If another program has modified the archive since Archive Manager opened the archive, choose View Reload to reload the archive contents from disk.

For information on how to customize the way that Archive Manager displays the archive contents, see engrampa-archive-custom.

For more advanced tasks, use an application installed on your system. For more information, see engrampa-view-archive-file.

### To View a File in an Archive

To view a file in an archive follow the steps described in engrampa-modify-archive-file. If you save the opened file, click Cancel when Archive Manager asks confirmation to update the file in the archive.

### To Test the Integrity of an Archive

Sometimes an archive can be damaged for some reason, to check whether an archive is damaged, choose Archive Test Integrity:

- If the archive contains no errors, Archive Manager opens the Test Result dialog to list each file in the archive, and indicates that each file has status `OK`.

- If the archive contains some error, Archive Manager opens the Test Result dialog displaying the part of the archive contains the error.

A damaged archive can be impossible to extract, this can bring to a loss of data. For this reason you should test the archive integrity before deleting the original files.

If the archive contains encrypted files, Archive Manager asks the password of the archive before performing the test.

Not all the archive types support the integrity testing, the following is the list of archive types that can be tested for integrity: 7-Zip, RAR, ZIP, ACE, ARJ and Zoo.

#### Suggeriment

To test the integrity of an archive that doesn't support the integrity testing, extract all the files from the archive and check that the operation is completed successfully.

## Customizing the Archive Display

You can customize the way that Archive Manager displays the archive contents, as follows:

- Switch between folder view and file view. For more information, see engrampa-view-type.

- Specify the order in which to display files in the list. For more information, see engrampa-view-sort.

- Display additional details about the contents of the archive. For more information, see engrampa-extra-info.

Archive Manager updates the display immediately, when you make any of the above customizations.

### To Set the View Type

If the archive contains folders, you can show the archive contents in either folder view or file view.

#### Folder View

Archive Manager displays the archive contents in folder view by default. To explicitly select folder view, choose View View as a Folder.

In folder view, Archive Manager shows folders in the same way as a file manager shows folders. That is, Archive Manager indicates folders in the display area with a folder icon and the folder name. To view the contents of a folder, double-click on the folder name.

The folderbar, which Archive Manager displays only in folder view, contains the components described in the following table.

Component | Descripció
Shows icon to navigate backwards in location history list. | Click on this button to navigate backwards in the location history list.
Shows icon to navigate forwards in location history list. | Click on this button to navigate forwards in the location history list.
Shows icon to navigate up one level in folder tree. | Click on this button to navigate up one level in the folder tree.
Shows icon to open the top-level folder in the archive. | Click on this button to open the top-level folder in the archive.
Ubicació | This field shows the full pathname, within the archive, of the current folder. To change to a different level in the folder tree, type the new location in the Location text box then press Return. Archive Manager displays the contents of the new location.

#### File View

To select file view, choose View View All Files.

In file view, Archive Manager displays all files in the archive, including files from subfolders, in a single list.

### To Sort the File List

You can sort the file list by name, size, type, modification date, or location.

To specify a sort order, click on the heading of the corresponding column.

To reverse the sort order, click on the column heading again.

For example, to sort the file list by modification date, click on the Date modified heading. Archive Manager rearranges the file list to display the files by modification date, starting with the earliest. To display the latest files first, click on the Date modified heading again.

Archive Manager always performs a secondary sort based on the file name. In the above example, Archive Manager sorts by name any files that have the same modification date.

### To Display Additional Details

To open the Last Output dialog, choose View Last Output:

- If you tested the archive in the current Archive Manager session, the Last Output dialog displays the results of the last test.

- If you did not test the archive in the current Archive Manager session, the Last Output dialog displays a list of all files in the archive, but does not indicate any status for the files. Instead, the Last Output dialog provides the compressed size of each file and the percentage of compression, and the date and time at which the file was last modified.

## Utilitzar el gestor de fitxers per treballar amb un arxiu

You can use the file manager to add files to an archive, or to extract files from an archive.

### To Add Files to an Archive by Using the File Manager

You can use the file manager to add files to an archive, in the following ways:

- Drag the files into a Archive Manager window from a file manager window.

- Use the file manager popup menu to add the files to the archive.

To use the file manager popup menu to add files to an archive, perform the following steps:

1. Right-click on the files or folders in a file manager window.

2. Choose Create Archive from the file manager popup menu to display the Archive Manager Create Archive dialog.

3. Enter the archive name, without the file extension, in the Archive text box.

4. Choose the archive type from the drop-down list.

5. Choose the location where to save the archive file, from the Location drop-down list. If the location is not present in the list choose Other... to select it with the Location dialog.

6. Select the required create options clicking on Other Options. For more information about the create options, see engrampa-create-options.

7. Click Create to add the selected files to the root folder of the specified archive.

   To select any of the advanced add options, you must invoke Archive Manager as described in engrampa-to-start.

### To Extract Files From an Archive by Using the File Manager

You can use the file manager to extract files from an archive, in the following ways:

- Drag the files from a Archive Manager window into a file manager window.

- Use the file manager popup menu to extract the files from the archive.

To use the file manager popup menu to extract files from an archive, perform the following steps:

1. Right-click on the archive in a file manager window.

2. Choose Extract Here to extract all of the archive contents into the directory where the archive is located.

If the archive is encrypted, Archive Manager will ask to enter the password before extracting the files.

## Opcions de creació

When creating a new archive, or when converting an existing archive to another format, click on Other Options to specify the following advanced options:

Contrasenya

- Type the password that will be used to encrypt the archive. If no password is specified the archive will not be encrypted.

  Not all archive types support encryption. For more information about file encryption, see engrampa-encrypt-files.

Encrypt the file list too

- If this option is selected, the password will be requested even to view the list of files contained in the archive, otherwise it will be requested only to extract the files from the archive. This option is available only if a password is specified.

Split in volumes

- Select this option to split the archive in more files of the specified dimension.

  Only 7-Zip and RAR archives support this feature.

## Opcions d'afegiment

The Add Files and Add a Folder dialogs provide the following option:

Add only if newer

- Select this option to add the specified file to the archive only if the archive does not contain the specified file, or if the archive contains an older version of the specified file. Archive Manager uses the modification date to determine which file is the most recent. If the version of the file in the archive is the most recent, Archive Manager does not add the specified file to the archive.

  If you do not select this option, Archive Manager adds the file to the archive and overwrites the previous archive contents.

  ### Suggeriment

  If you use Archive Manager to create backups, the Add only if newer option is very useful. For example, the archive `backup.tar.gz` contains a week-old backup of your home folder. To update the archive to contain a current backup of your home folder, perform the following steps:

  1. Open the `backup.tar.gz` archive in Archive Manager.

  2. Choose Edit Add to display the Add a Folder dialog.

  3. Select your home folder.

  4. Select the Add only if newer option.

  5. Click Add.

  Archive Manager automatically adds to the archive all files that you created during the last week, and updates all files that you modified during the last week. However, Archive Manager does not remove from the archive the files that you deleted during the last week. The archive update operation is much faster than doing a full backup of your home folder.

### Add to Folder Options

The following options are available in the Add a Folder dialog and allow to automatically select and add all files that satisfy certain criteria:

Include files

- Type a filename pattern in this text box to include files with names that match the specified pattern. See engrampa-pattern for more information about filename patterns.

Exclude files

- Type a filename pattern in this text box to exclude files with names that match the specified pattern. See engrampa-pattern for more information about filename patterns.

Exclude folders

- Type a filename pattern in this text box to exclude folders with names that match the specified pattern. See engrampa-pattern for more information about filename patterns.

Include subfolders

- Select this option to add all files that match the specified pattern, from the current folder and from subfolders.

  The filename, not the subfolder name, must match the specified pattern.

  If you do not select this option, Archive Manager adds the matching files from the current folder only.

Exclude folders that are symbolic links

Actions

- Seleccioneu les opcions d'extracció següents:

  Re-create folders

- Select this option to reconstruct the folder structure when extracting the specified files.

  For example, you specify `/tmp` in the Filename text box and choose to extract all files. The archive contains a subfolder called `doc`.

  - If you select the Re-create folders option, Archive Manager extracts the contents of the subfolder to `/tmp/doc`.

  - If you do not select the Re-create folders option, Archive Manager does not create any subfolders. Instead, Archive Manager extracts all files from the archive, including files from subfolders, to `/tmp`.

Overwrite existing files

- Select this option to overwrite any files in the destination folder that have the same name as the specified files.

  If you do not select this option, Archive Manager does not extract the specified file if an existing file with the same name already exists in the destination folder.

Do not extract older files

- This option is only effective while the Overwrite existing files option is selected.

  Select the Do not extract older files option to extract the specified file only if the destination folder does not contain the specified file, or if the destination folder contains an older version of the specified file. Archive Manager uses the modification date to determine which file is the most recent. If the version of the file in the archive is older, Archive Manager does not extract the specified file to the destination folder.

  If you do not select the Do not extract older files option while the Overwrite existing files option is selected, Archive Manager extracts the specified file from the archive and overwrites the previous contents of the destination folder.
