The xxl file extension is associated with an old compressed archive format produced by File Archive Handler, a utility dating from around 1999.
An XXL archive stores files in compressed form for packaging and storage. It belongs to the File Archive Handler software rather than to a widely used modern archive standard, and the format appears to be legacy.
To open an xxl file, use the original File Archive Handler program. As far as known, it may be the only program that can access this format, and current archive utilities may not support it.
There is no known dedicated converter for the xxl file format. If File Archive Handler can open the archive, extract its contents and repack them in a more common archive format.
