I had a crash on my Windows 7 Home Premium and after that was resolved, all my folders under "Local Folders" in my Thunderbird ver. 24.5.0 disappeared! I have 6 accounts but they were not affected and all my emails are there. However I had many folders under Local Folders with very important business messages, but they are not there anymore. I found one of the main folders in my profile, under "Mail" but it contains only a very few sub-folders. How can I recover these folders and where are they now?
