By default, all older versions
in a file archive are stored uncompressed in their original
format on the archive server. To save space, you can enable compression on all file versions older than the most
recent version. The most recent version is always stored
uncompressed for optimal performance during transfers between
client and server.
To enable archive server
compression on the server, we recommend using the SOLIDWORKS PDM policy. Alternatively, add the registry key that activates the compression
manually for each vault.
