Creating Archives and Adding Files

To create a new archive in Ark, choose New (Ctrl+N) from the Archive menu.

Create an archive

You can then type the name of the archive, with the appropriate extension (tar.gz, zip, 7z, etc.) or select a supported format in the Filter combo box and check the Automatically add filename extension option.

To add files or folders to the new archive, choose Add File... or Add Folder..., respectively, from the Archive menu.

An alternative way to add files to an archive is to drag one or more files from e.g. Dolphin into the main Ark window, and it will be added to the current archive. Note that files added in this way will always be added to the root directory of the archive.

Additional options are presented in collapsible groups at the bottom of the dialog.


A higher value generates smaller archives, but results in longer compression and decompression times. The default compression level proposed by Ark is usually a good compromise between size and (de)compression speed. For most formats the minimum compression level is equivalent to just storing the files, i.e. applying no compression.

Password Protection

If you create a zip, rar, 7zip and jar archive you can protect it with a password.

Create a password protected archive

Choose whether to require the password before showing the list of files. This is called header encryption and is available only with the rar and 7zip formats. Header encryption is enabled by default (when available), in order to offer the maximum protection for novice users.

Multi-volume Archive

With the zip, rar and 7z formats you can create multi-volume archives, also known as multi-part or split archives.

A multi-volume archive is one big compressed archive split into several files. This feature is useful if the maximum file size is limited, e.g. by the capacity of a storage medium or the maximal size of an email with attachments.

To create a multi-volume archive, check the Create multi-volume archive checkbox and set a maximum Volume size in the dialog. Then add all files to the archive and Ark will automatically generate the required number of archive volumes. Depending on the selected format the files have an extension with consecutively numbering scheme e.g. xxx.7z.001, xxx.7z.002 or, or xxx.part1.rar, xxx.part2.rar etc..

To extract a multi-volume archive, put all archive files into one folder and open the file with the lowest extension number in Ark and all other parts of the split archive will be opened automatically.
