Under enterprise PDM (the full PDM but as workgroup is only a lite version it should work too), you just have to synchronize the whole vault on a PC.
That's what I do on my computer: 130GB of data synchronized each time I reconnect to the safe.
As you have all the files on your PC at the moment, you can make a copy of the root directory of your vault (I do them using freefilesync: a nice little freeware tool).
If you don't want to do a permanent sync (I don't recommend it because it's very long at the first connection of the day), you can do a "get latest version" on the root of your safe.
If you want to do like me, it's at the level of the EPDM user (or group) settings where you have to put the root directory of the vault in the directory options to synchronize (usually we only put library directories with this kind of option).
It's the workgroup, not the standard pdm (the standard pdm I know how to do it, I created a special account with full replication at the connection to use offline, the full sync is too long).
In the workgroup on the server under data I only have special files. And when you extract a file it copies all the components of the assembly to a flat temporary directory. Maybe I have to look in the extraction options if I can change the settings.
Indeed, there is no direct solution. Exporting Workgroup PDM directly would put all files flat in a Windows folder.
With the discontinuation of this solution, Dassault Systèmes has developed an export tool to PDM (Std or Pro), which allows you to rebuild your own tree structure. One solution is to export your PDM Workgroup vault to PDM, and then output the data from PDM to Windows.
Knowing that PDM Standard is included as early as Solidworks Professional.
Thanks for the info. If it's possible I'm interested, exporting from a standard pdm to window I know how to do it, so would you know where to find this utility?
