Hello, I installed BtSync, set up directory synchronization for my /DATA directories on both my notebook and the desktop PC and immediately stopped BTSync after that to define the directories to be excluded in the .SyncIgnore file. The way I did it is to simply list the subdirectories I didn't want to sync, so it now looks like: .DS_Store.DS_Store?._*.Spotlight-V100.Trashesehthumbs.dbdesktop.iniThumbs.dbAndroidStudioProjectsAStudio-GradlesbakBluetoothDropboxeBooksEigene BilderEvernoteGoogle Desktop Datamoz-profilesMy PSP FilesPicasa EditsPicasaLibAfter updating these files on both computers, I started BTSync again. However, it started to sync files contained in the PicasaLib directory! (it also created a backup copy of these files in the .SyncArchive directory). Can it be that it 'remembered' the previous setting and didn't re-read the .SyncIgnore file again after the restart and refresh the list of files to be copied? If so, how can I force it to do so? What was even worse however, and I also don't have any explanation for: it did overwrite a newer version of a file on the desktop computer (a Truecrypt image file) - how can that happen?! Isn't the software supposed to copy only newer files? Luckily really, the backup copy was created, so at least my work of 2 weeks hadn't been lost. BTSync looks like exactly the tools I'm looking for, but I really have to trust it. thanks, r.
