krusader can't enter hidden archive

[Martin Vysny]

Hi all, thanks for your wonderful work on Ubuntu :)

The documentation at https://docs.kde.org/trunk5/en/extragear-utils/krusader/archives.html states that Krusader should support so-called hidden archives - zip files with extension different than .zip.

I have an apk file (Android application file), which is a zip file but with the .apk extension. Pressing right-arrow on the file does nothing - Krusader won't enter the file, even though it is a zip file.

Workaround is to rename the file to myapp.apk.zip; that will enable right arrow to work in Krusader and Krusader is now able to enter the archive and show its contents.

Krusader has probably a whitelist of extensions of such hidden archives, since it is able to enter, say, .jar files.
