Description Helge Hielscher 2005-03-09 12:30:14 UTC

Version:           2.4.0 (using KDE KDE 3.3.2)
Installed from:    Mandrake RPMs

It is getting more common that applications store there data in compressed files, but do not use an extension that is common for archives and are often not known by ark.
If I open such a file, I get asked what kind of archive it is. 
What I want ark to do is: 
1) check the archive format automatically using the file command or a similar method
2) in the dialog preselect the archive format to what is most likely
3) a checkbox "remember the filetype if this file can be opened sucessfully"

With r847739 kde4 ark looks at file content to figure out mime type. This partly fulfills this wishlist item.

Improve detection of mimetype when opening archive

Previously, the filename extension had higher priority than file content
when determining mimetype. When opening an archive that had a wrong
extension (as in bug 265971), this resulted in Ark failing to open it.
With this commit the mimetype is determined from file content.
Additionally, a warning is shown in console output when mimetype from
extension and content do not match.

For tar.gz, tar.bz2 and tar.xz archives, the mimetype from filename
extension is still used. This is due to these archives being detected as
singlefile gz, bz2 and xz archives when using content, and Ark would
then use the singlefileplugin instead of the libarchive plugin.
