[Q] how to back up / restore weixin / wechat
message history lost - happened once or twice before - on this round perhaps due to unauthorized access - don't know why anyone would want to hack to my wechat, but...
yes, i know that titanium backup can do this - only, i happen to have a backup of the app's files from the SD card that's much later than the latest titanium backup.
so i've overwritten the message directory on the SD card
with the latest backup, but the app doesn't recognize the stuff between the titanium backup / the later files. how to force it to? how does it manage these files anyway?
(the answer to this might also help in managing the app's thousands of files in order to keep the phone functioning.)
