Doesn't handle Android's inactive app archive so I came back and found it hasn't been backing up for a month. No notifications, no warnings, app looks normal and showing green "success" except if you look closely at the last "successful" sync it's a month ago. Strange V1 and V2 split with different screens depending on when you created the folder pair. Slow transfer, concerned with other reviews that it's not checking sync has suceeded and developer won't reply to explain.

Very useful, with about 11 folder pairs. I have encountered a problem with certain files, specifically photos. I am about 86 years old and the 1970 limit on android file transfers is only 56 years ago. That means that pictures of me taken before age 30 can't be backed up with foldersync. The only option I see is to manually copy the files. Fortunately these old files are pretty static and will not require frequent backups.

seemingly no retry logic. possibly unnecessarily reanalysis means syncing Camera dir (rather than frozen album dirs) requires hours (days?!) or reanalysis. rsync would be much faster. even after breaking up folders into small chunks (absolutely ridiculous), fails constantly with maybe 5% progress each time. seemingly no helpful options to ensure reliability. file conflicts indicate corruption during transfer (which is possible to check for) but can't yet confirm. good luck
