Thank you for your reply! My suspicious was aroused by two particular things: firstly, that in the 'name' column, instead of the name of the folder I had chosen ('Audiobooks') the folder had a name I did not recognise ('AvFZ5MI1Tw6oxMEd25G8rQ'); and secondly, under the 'path' column, the path shown was to a different folder on a different disk. Thanks for confirming, so the 'troubleshooting' forum was the right place to post this, then! The error did occur again, affecting not just the one folder but several this time. Screenshots sent to syncapp@bittorrent.com as suggested. I hope you can fix the problem! Thanks.

On my laptop, several sync folders are on an external drive. I leave sync running all the time. I just noticed that, while the drive wasn't available, sync has grabbed (apparently randomly) a path to a different folder, on a different external drive. Now the original drive is back, it's saying 'folder not available' because it wants to sync with this folder it's randomly picked. Several other folders on the same drive aren't affected. It's a Macbook Air running Sync 1.4.106 on OS X 10.10.1. I previously ran Sync up to 1.3 with a similar set up and never had this problem; I installed 1.4 from scratch (i.e. re-adding all the folders) and it's been fine for a 5 days. I'm going to remove the rogue folder and re-add the proper one. The history doesn't indicate any damage done, and I hope this doesn't happen again - but any idea what the cause is, or how I can minimise the risk?

I've had a bit more time to play with this. One of the machines is a Macbook Air (OS X 10.8.4) and BTSync 1.1.70 behaves differently on different networks. When it's on the same network as the other machine (Mac Mini is OSX 10.7.5) everything syncs fine. It has also been able to sync fine from another remote network. When on the network where I had the initial problem (a corporate network), it won't sync any files. I have noticed that it only syncs folders when the iOS app is open (and the phone is on the same network as the laptop). As noted above, anything synced to the phone then syncs to the laptop; and since the phone automatically syncs the folder structure I think this is why I saw folders syncing but not files. So in my case I think I have a firewall problem with the laptop on one particular network. Odd thing is: it doesn't affect the iOS app...

I have the same problem. BTsync 1.1.70 running on OS X (one machine 10.8.4, the other 10.7.5) across the internet. Folder sync. Files don't. When I open the app on the phone (iOS 6), it can see the files in both machines. Files added on the phone are added on both machines. I haven't had a chance to try with Macs on the same LAN yet, but will try that later.
