Thanks for the reply. I am not sure how the situations you described are possible. To my knowledge, I am not actively using any other programs that "sync." I never enable cloud or automatic backup options as I prefer to routinely manually backup important files, exactly because I have had bad experiences with programs that automatically do things like that. I created the folder strictly to try out BTSync and used it for nothing else since then. It instantly re-appears as soon as I close and refresh, even if I am unplugged from the internet. I never used BTSync on any other accounts or devices, I simply installed it on my PC and tried running it on my PC. Furthermore, when I originally uninstalled BTSync, I did it as you described, including checking that checkbox to remove everything. When that did not stop the folder from re-appearing, I restarted. After restarting and the folder still kept re-appearing, I checked for any location remaining BTSync files/folders could be at and deleted any remaining folders (including the one you mentioned). I then went into the Registry Editor and searched for all remaining registry entries that references "BTSync" or the folder that I am trying to delete, and erased those as well. The folder is still re-appearing.
