I have run Gmail Backup twice, and it claims to have backed everything up. The first time it took a long time and I could see it processing every message in the window. The second time, It skipped over most messages and said something along the lines of "message already backed up" in the window, and then processed the newest messages.
But when I open the directory my emails are allegedly saved, all i see is one 7kb file named "gmail-backup.MO" Hidden files are already set to visible, so that's not it. I just don't seem to actually have my emails on my machine, despite what Gmail Backup claims. Unless I'm missing something here, I can't find my actual backed up messages anywhere.
I have not changed the default backup directory. It is still ".../Program Files/GmailBackup/Messages/da/LC_MESSAGES/" There's just nothing there except one tiny .MO file.
