Okay, I spoke a bit too soon. I think I've just found a solution. After taking the above steps, then based on this StackOverflow post, I was able to use the program ShExView to disable all Resilo Sync and BT Sync related shell extensions. After a restart, I was able to delete the files and the shell extensions seem to have successfully being blocked from starting up and writing more logs. I would seriously suggest a sticky thread on this topic that summarises the solutions, so people like me don't need to spend hours on their day off trawling through 5 different forum threads and websites to figure this out. And of course, this solution only works for those who have uninstalled the App, so you may want to also present a solution for users who are still using it... FYI I'm sorry to say that this bug was the reason that I stopped using the app on this and other non-windows devices.

I still have this appalling bug with BitTorrent Sync / Resilo Sync writing un-deleteable GB-size ShellExtIO.log files to my HD, with constant kbps disk usage, even months after uninstall. There are several threads on this topic: forum.resilio.com/topic/42362-bittorrent-sync-logging-every-single-filename-i-see forum.resilio.com/topic/42279-what-is-shellextiolog-cant-delete-it forum.resilio.com/topic/42564-shellextiolog-growing-out-of-control I have two ShellExtIO.log logs being written, in C:\Users\<my user>\AppData\Roaming\BitTorrent Sync C:\Users\<my user>\AppData\Roaming\Resilo Sync I've tried the following recommended steps found in those threads: I furthermore unregistered two more DLLs within the AppData\Roaming folders. These steps did not fix the problem. This allowed me to delete at least one of the logfiles (in Resilo Sync folder). The other one I still couldn't delete. As soon as I deleted it, it came back and started growing in size anyway. Please advise any further steps possible here. This is a serious, malware-level bug that must be harming thousands of users.
