I had the same issue. I recognized this with Microsoft Office documents, but it may apply to others as well. When creating a .docx file on computer A it gets synced to my other comps B & C, as it should. When I work on that doc, it will at some time point be back resynced from my comps B and C to A, although the latest version is on A, and the others have never been touched. I got only a small notification that "file.docx has been downloaded", which I dismissed as "the file mods have been synced to my other comps". So I continued to work on it. Using autosaving and saving shortcuts to save, I never recognized that the document I am working on is not any more in its original location but in $share/.SyncTrash. I kept modifiing this file and saving for approximately a week. Today, after restarting by using the doc in the finder, all changes were missing. It took me 5 hours to find that they are in SyncTrash and my current version has been replaced with an old one. Auto backups did not cover the files, as they were not anymore in the correct folder. Thus, there is an issue in identifying opened files, which should be protected, and file modification date, since they will get the date of the transfer and are thus always newer after transfer! OSX 10.8.4 on all computers. BTsync 1.1.27. Hope this helps to solve the issue. Reported as a bug in the bug-report feature of the app. I closed the app on all my devices, because this is a NOGO-Issue. But apparently it keeps syncing and syncing! I am not able to identify the correct process to kill via top or ps aux, so I would be grateful for the process name. I will not use BT anymore until this issue is properly closed. Cheers, Alex
