Might be a dumb question . . . but is the Backup “target directory” the directory I am backing up to, or from? In Setttings\General\Backup, it shows the target directory as “C:\Users\name\AppData\Roaming\eM Client”, but it seems to me this should be the source directory (where my email data is stored), and the target directory should be a different location. Is this correct?
No, that target directory you have sent me here is place where is stored eM Client’s database.
Backup target directory is set by default in Document, but you can find and change it here: Tools - Settings - General - Backup.
