I have a large file that has some sparse regions. I created a TAR file containing that large file by running tar Scf some.tar somefile. Then I tried opening the file with Ark, which reports that the file is corrupt, and only allowing me to open it in read-only mode, and even in that read-only mode, the large file is not shown.
Running tar tf some.tar lists the large file properly and terminates successfully. Extracting the file with tar xf some.tar also works and reproduces a large sparse file (I’m using the Ext4 file system).
Is this a known issue in Ark, or should I report a bug?
