Hi, I'm running TB 78.7.1 on Windows 10 and have my local folders saved to a USB drive. My USB was assigned as the F: drive and I'd configured TB to use this drive for the local folders. After many successful uses of the USB on the F: drive, the next time I started TB I noticed that my PC had assigned the USB to the G: drive. Within TB, I changed the local folder from F: to G: and restarted TB as prompted. After restarting, TB had deleted all the folders on my USB! The USB now has files such as: [Gmail].sdb [Gmail].msf filterlog.html inbox.msf msgFilterRules.dat Templates.msf Trash Trash.msf Unsent Messages Unset Messages.msf I found a file recovery tool and was able to restore some of the deleted files. This was a painstaking process. After restoring the files and folders on the USB I was able to get TB to recognize my local folders again using the F: drive. Today, I plugged in my USB and once again the PC assigned it to the G: drive while TB was configured with F:. Instead of changing the TB configuration, I decided to use 'Computer Management' and changed the USB drive from G: to F:. I kicked off TB but it still deleted my local folders and left files similar to the ones listed above. Why is TB behaving this way? I need to use the USB for my local folders since this is a shared PC. Is there a way to stop TB from deleting my local folders on my USB or is this a bug? Thanks in advance for any help!
