            Bug ID: 507427
           Summary: "No space available on device" message when extracting
                    multi volume rar archive
    Classification: Applications
           Product: dolphin
      Version First 25.04.3
       Reported In:
          Platform: EndeavourOS
                OS: Linux
            Status: REPORTED
          Severity: normal

          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

SUMMARY
"Right click -> Extract" on a multi volume rar archive shows an error message
claiming that there's "No space available on device" even though enough space
is available.
STEPS TO REPRODUCE
1. Take some large input file. Let's say 20 GiB.

2. Compress it such that the number of parts multiplied by the size of the
input file exceeds your free space on the device. The command should look like
this: `rar a out.rar input.bin -m0 -v50m`. The `50m` is the size per part.
Adjust as needed for your free disk space. The `-m0` just disables compression.

3. Rename input file so there's no name conflict.

3. Right click -> Extract -> Extract here

OBSERVED RESULT
Error messages claiming "No space available on device".

EXPECTED RESULT
Archive extracts successfully.

ADDITIONAL INFORMATION
Couldn't reproduce with a 7z multi volume archive. Looks specific to the rar
format.
