I suspect there is a problem with the way zero length files are handled in file extract to restore from backup.
I have been attempting to restore files. I get this message “Error message: Could not extract file from archive.” I repeated the backup process to generate a different file and it failed at the same point in the restore.
When I look at the file that cannot be extracted, it is a zero length file. When I remove the file from the .zip file and attempt it again, the restore continues until it hits a different zero length file. If I just unzip the files into appropriate directory, from a command line, they extract as expected.
Would you take a look at this on your end ?
