I recently moved a thunderbird profile a new computer and now some of the folder names have random numbers in them. I assume this is because there were special characters in the names. But they displayed correctly on the old computer. I copied the entire thunderbird directory under C:\Users\username\AppData\Roaming\thunderbird to the new one. Did one of the files get corrupted during transfer? Any way to fix this? Using win 10 and thunderbird 68.2.2 64bit. They have been using their email for a couple of days now, so I can't copy the entire profile again. In an attempt to fix I deleted the following files and that did not help: panacea.dat parent.lock session.json xulstore.json all .msf files Any help would be appreciated. see pic
