File Manager fails to extract an archive in Plesk: Unable to extract

Symptoms

• An archive file can't be extracted with Plesk File Manager:

  Unable to extract /httpdocs/example.zip: filemng failed: Archive: /var/www/vhosts/example.com.com/httpdocs/example.zip

• Running an archive test with the system utlities returns a lot of errors:

  # unzip -t /var/www/vhosts/example.com.com/httpdocs/example.zip
  example/image/cache/dream1/button/#U87a2#U5e55#U5feb#U7167 2018-11-20 21.14.52-100x100.png: mismatching "local" filename (www/image/cache/dream1/button/???????????? 2018-11-20 21.14.52-100x100.png),

Cause

The archive file is corrupted, and can't be extracted with neither Plesk nor any other tools.

Resolution

To resolve this, recreate the archive using the same tools that were originally used to create it, and then reupload it to Plesk to extract it normally.
