SUMMARY Ark can't open files created by KDE Krita (*.kra format - renamed *.zip) STEPS TO REPRODUCE 1. Create a file in Krita, save as native *.kra format 2. Try to open with Ark OBSERVED RESULT ""Loading the archive /home/mappu04/test.kra failed with the following error: No suitable plugin found. Ark does not seem to support this file type."" EXPECTED RESULT Ark should have shown the files inside the .kra archive. Same result as `bsdtar fl test.kra`: Krita zip files contain mimetype maindoc.xml documentinfo.xml preview.png test/layers/layer1 test/layers/layer1.defaultpixel test/layers/layer1.icc etc etc etc... SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian Buster (testing) KDE Plasma Version: 5.14.5 KDE Frameworks Version: 18.08.3 Qt Version: 5.11.3 ADDITIONAL INFORMATION I have all default plugins enabled. Clearly libarchive is able to list the files inside this *.kra archive as evidenced by the bsdtar command output. I disabled the Info-Zip plugin inside Ark, and left the Libarchive plugin enabled, but still got this error message in Ark. Renaming the file to foo.kra.zip actually didn't help neither, so this isn't just a file extension issue...
Considering the fact that unzip can unpack these files, I kinda agree. Ark should be capable of doing this as well.
Are Krita files really just renamed zip archives? If yes, then the krita mimetype in shared-mime-info should have the following like (which will make it compatible with ark): <sub-class-of type="application/zip"/> Moving to krita for now. I can fix it in shared-mime-info if the Krita developers can answer my question above.
Yes, it's a zip file, just like openraster and opendocument files. However, if I rename a .kra file to .zip, akr can open it just fine. Note that in the current master branch of Krita, there's an option to enable zip64 support; ark won't be able to open that because it depends on karchive, which doesn't support that.
In any case, that change in shared-mime-info should be done. We don't have a product for that, do we?
