File closed by user but still locked by user

This problem happens after migrating file server to Windows Server 2012 R2. I do not know what exactly cause this thing. As responsible IT guy, this problem need to be solve cause the file that are locked used by other user which need updating.

So let go on how I solved this annoying little problem. Actually to solve this mystery is quite simple i should say. Just Open Control Panel - Administrative Tools - Computer Management.

Expand the Shared Folders.

Select Open Files. After that choose which file that you need to close and right click. Close Open File. tadaaaaa...

Before this i use command prompt..haha..when user see we use command prompt they will be like whoaaa..hahaha..

GOOD LUCK.
