I am unclear whether you mean your folder on the Members store @ DMS ( \\files\members) or if you mean the “mapped” folder that appears on the clients when configured to so do.
For the former, here is some more info

As stated prior, you’ll be creating this yourself, it is TEMPORARY, 0777 perms mean anyone can manipulate it (including delete, which occasionally accidentally happens), and is accessible on the mapped M: drive (or UNC as shown).
For the latter, here is some further elucidation. If this is what you’re asking about, it will be whereever in the file system you designated when configured.
Without a Mac client at-hand to double-check, I can’t be certain, but to my recollection, you can do this to/from any file/directory (you have permissions for) on either system. If drag-n-drop doesn’t work, try copy/paste. They’re nominally the same, but sometimes one seems to work while the other does not.
