Despois de ter aberto un arquivo pódense realizar diversas operaciónssobre os ficheiros dentro del. Ao seleccionar un ficheiro e usando o menú Acción, pódese escoller o que fazer:

Once an archive has been opened in Ark, it can be extracted. To quick extract files from an archive, you can select Extract... from the Action menu. This opens a submenu with previously accessed folders, and you can select to quick extract into any of them. Clicking on the check mark at the right side of the Extract button in the toolbar performes the same action.

To open the Extract dialog click the Extract button in the toolbar or use the shortcut Ctrl+E. This dialog allows you to select where you will extract files to. The default location is the folder the archive is in.

You can specify to extract the files into a subfolder. The default name of this subfolder is the first part of the archive name, but you can edit it to your needs. If you want to preserve paths when extracting, select this option. You may also choose to open the destination folder in Konqueror or Dolphin once the extraction is complete.

If a file in the archive list is highlighted, you can also select which files to extract:

Para crear un arquivo novo no Ark, escolla Novo no menú Ficheiro.

You can then type the name of the archive, with the appropriate extension (tar.gz, zip, bz2 etc.) or select a supported format in the Filter combo box and check the Automatically select filename extension option. To add files to the archive, choose Add File... from the Action menu. If you want to add an entire folder to an archive, choose Add Folder... from the Action menu.

Unha forma alternativa de engadir ficheiros ao arquivo consiste en arrastrar un ficheiro do Konqueror, do Dolphin ou do escritorio para a xanela principal do Ark para que se engada así ao arquivo actual.
