Managing archives:
1] Create a new archive :
To Create a new archive with Archive Manager by following these steps:
Select Archive Manager ▸ New Archive.
Name your new archive file and choose the location where it will be saved, then click Create to continue.
By clicking Other Options you can set a password or split your new archive into smaller, individual files by selecting the relevant option and specifying the volume for each part in MB.
Add the desired files and folders to your archive by pressing + in the toolbar button.
Check the box next to the files and folders that you want to add.
Once you finish adding files, the archive is ready.


2] Open an archive:
You can open an existing archive with Archive Manager by clicking Archive Manager ▸ Open…
You can also drag and drop an archive into an open Archive Manager window.

3] Edit an archive :
With Archive Manager you can edit an existing archive by adding new files, removing unwanted ones or by renaming them. You can work with folders in the same way as with files.
A] Add files
Add files to an existing archive by following the instructions for creating an archive.
B] Remove files
Right-click on the file and choose Delete, or press Delete.
C] Rename files
Right-click on the file and choose Rename…. Enter the new file name into the dialog which has opened and confirm the new name.

4] View an archive There are two ways to view an archive:
A] View all files Click View ▸ View All Files. Archive Manager will list all files inside the archive. You will see their names, sizes, types, dates of the last modification and locations. You may use the column headings mentioned above (name, size…) to sort the files in your archive. Do this by clicking on them; you can toggle to sort in reverse order.
B] View as a folder This view displays the classic directory structure. To use this, click View ▸ View as a Folder.
While viewing your archive in this way, you can press F9, or click View ▸ Folders option, to see a tree view of the folders in the side pane. It allows you to navigate easily between folders.

5] Extract an archive
Extract files from an archive using Archive Manager by following these steps:
1] Open an archive.
2] Click Extract.
3] Choose where you want the archive to be extracted to in the file chooser. This will be the destination folder. See advanced options for extracting archives for more extraction options.
4] Click Extract.
5] If an archive is protected by a password, Archive Manager will request it. Type in the password and click OK.
6] The application will show you the progress bar in a new dialog. If the extraction completes successfully, you will be asked whether you want to: a]Quit to close Archive Manager.
b] Show the files to view the destination folder with Files. c] Close the dialog.

Advanced options for archive extracting
Archive Manager offers different options for extracting an archive. You can see these options in the Extract dialog. At the bottom of this dialog, you can decide if you want to extract:
1] All files
All the files and folders in the archive will be extracted.
2] Selected files
Archive Manager extracts only the selected files. You need to select the files that you wish to extract before you click Extract. Do this by clicking on the file name. Use Ctrl and Shift keys, to select more than one file.
3] Files
You can type in the names of the files that you want to extract. Separate individual files using a semicolon (;).
The file name needs to be followed by a file extension. You can use the asterisk (*) as a wild card. For example, to select all .txt files, type *.txt. You can specify in the file chooser dialog whether you want to:
1] Keep directory structure
Tick this option if you want to keep the directory structure as it is in your archive.
2] Do not overwrite newer files
This option will not overwrite existing files with the same name, which have a more recent modification date than those which are in the archive.

Password protection
You can encrypt an archive with a password so that only you and those with whom you choose to share the password are able to access it.
Note that the password can still be guessed, so for highest security, use a good password.
Archive Manager allows you to encrypt an archive with a password only in specific circumstances.
Set a password to encrypt data in a new archive by following these steps:
1] Start creating a new archive.
2] At the bottom of the file chooser dialog you can choose a File Format and enter a password into the Password field in Other Options.
3] You may not be able to type a password, because not all archive types support encryption, so choose an archive type that can be password protected before setting a password.
4] Continue with creating a new archive.
Protect an existing archive by setting a password:
1] Open an archive.
2] Click Edit ▸ Password…
3] Type a password into the Password field.
4] If you want to encrypt the list of files tick Encrypt the file list too.
5] Click OK to continue.
Archive Manager will encrypt only new files which will be added to the archive!.



Test integrity:
Archive Manager allows you to check whether the compressed data in an archive contains any errors. Do this by clicking Archive ▸ Test Integrity.
The dialog with the Test Result will pop up, listing the files tested, with the test summary at the bottom.
The integrity test verifies that your data is not corrupt.

Troubleshooting
Problem opening an archive :
If you cannot open an existing archive with Archive Manager, check the format of your file. Some types of archive may require additional plugins; the installation process for these varies between different distributions.

Problem setting a password:
Archive Manager does not add password protection for an existing archive. While working with such an archive, you can only set a password for newly added files.
