choose the option to create an archive of any format below:
tar.gz
tar
tar.bz2
tar.lzma
tar.xz
tar.Z
tar.lz4
tar.lz

3. 

OBSERVED RESULT

Can also reproduce by creating a .arj archive.

This seems to be independent of the choosen format and it also happens if you create an archive via. Ark itself - not only via context menu.

The problem with progress bars is how you calculate them. In this case ark uses the file count, but this is cumbersome with big files or a mixed set with small and big files. File size might be a better option, but could be misleading if lots of small files slow down the process.

- At least for a single file operation the filesize would be helpful
- A data transfer rate would make a good addition
- One good solution might be to show two progress bars: current file and overall progress
