Hi Tacit/Anders,
Kudos on nice app.
Here's some feedback, you can do with has you wish.
1)
Sometimes the 'syncing' text does not go away after sync finishes, when I have been out of app (I think it was a 4-hour sync (a sync with no changes)).
2)
I use SFTP to linux, with legacy library. syncing a folder with 1 file of 1.5GB takes 10min to complete for additional syncs which does nothing. 'lsof' execution on the server showed rsync access to file on nas during the initial transfer from android to server of the file, but shows nothing on the subsequent syncs, and I didn't notice any router bandwidth usage either. Android uses 50-80% CPU the whole 10mins (HTC One m8). Initial sync of 44GB took 900mins (which is fine), subsequent (no-change) sync took 211mins. I'm not sure whether this is expected behaviour because foldersync does not keep state/md5 files, or if it is unexpected behaviour. There was nothing I could find on the faq regarding this.
Best Alex
