Hi

I've probably a useful hint:

Signal app files: on a public, but mounted network share (in this case X:)
Signal user data: on an UNC path (using windows folder redirection feature and server-sided user profiles) which is accessible with "%appdata%\Signal" or "\\domain.local\dfs_shares\userdata\[username]\appdata\Signal"

Finding this in debug log:
INFO 2021-06-22T10:02:33.810Z Warning: denying request to non-absolute path 'domain.local\dfs_shares\userdata\[username]\Anwendungsdaten\Signal\attachments.noindex\bb\bb50a1d174bc0e95369daf37159a4a862bf011acceb55b8e93be18cc9f0587f0'

Is there a cli switch to save the userdata to a custom (local) folder?
