I found a strange hidden system file inside an ordinary folder that's located in my D drive (D:\DownoadZ)
I showed the hidden files and also the system files, and I noticed there was a strange file (0 KB) I haven't seen before (I used to check my system for some reason).
However, this file is called "CA63EB6H." so it has no extension. Where I know there is no important system files supposed to be in that folder, I tried to delete it. But I always get a message says "cannot delete file: cannot read from the source file or disk".
Moreover, that file has no owner and can't be read so, I couldn't take the ownership (it has no security tab). And i can't be renamed or even deleted on the save mode. Also, I've tried to use move at boot to delete it but got nothing.
Somebody may say it's not a big deal! yeah it's not a big deal while the file is harmless.
But if anyone has a "guaranteed" idea please share it.
