Created attachment 103058 [details] Sample zip file from Ark containing gzip format archive instead of zip [Ark 2.19, KDE 4.14.2 on Linux Mint 17.3, Dutch locale] Reproduce: - Start Ark - New -> Save as -> e.g. test.zip -> Save - Add File -> select files -> Open - Close Ark Check from the command line: ~ > file test.zip test.zip: gzip compressed data, from Unix, last modified: Thu Dec 29 13:19:53 2016 (also see attachment) Identical result from Dolphin context menu: - Start Dolphin - Select one or more files - Right-click on files -> Compress -> As ZIP archive Using zip from the command line does result in a correct zip file. The result from Ark is not a normal zip file, and Windows users can't open it. This is a major problem for users who are not familiar with using zip from the command line. Note: this appears to be the same bug as #333835 https://bugs.kde.org/show_bug.cgi?id=333835 from 2014, but it is not (yet?) resolved in Mint 17.3 AFAICT
Sorry, but there is nothing that we can do. Please get in touch with the Mint developers and ask them to fix this bug in their ark package: https://bugs.launchpad.net/ubuntu/+source/ark/+bug/1388532 *** This bug has been marked as a duplicate of bug 340456 ***
OK, I will do that. Thanks for the fast reply!
