Bug ID: 506685
Summary: Ark fails to extract files from ZIP archives that are
packed with the "Deflate64" method. "Compression
method not supported"
Classification: Applications
Product: ark
Version First 25.04.3
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
SUMMARY
When opening a .zip archive in Ark, extracting a file that has the compression
method "Deflate64" will fail with the error message: "Compression method is not
supported". Files from the same .zip archive that have different methods such
as "Store" will extract without problems.
This problem only affects Ark. Using the "unzip" command will extract all files
from the same archive without problems.
STEPS TO REPRODUCE
1. Have a .zip archive with files that have mixed compression methods. For
example "Deflate64" and "Store".
2. Try to extract the file packed with "Deflate64". It will fail.
3. Try to extract the file packed with "Store". It will work.
OBSERVED RESULT
Files with "Deflate64" always fail to extract in Ark. They dont fail with the
terminal "unzip" command.
EXPECTED RESULT
Files should extract regardless of the compression method.
