File locks hang (Windows 7, distributing the ball). What could be the reason?

Question

Windows

In the network of one organization there is a "server" on windows 7. Files that are often changed and used by different people are shared.
Once in a couple of hours this problem occurs. The file is locked. And it won't unlock until you restart explorer or the server itself. Based on the resource monitor, the file is being blocked by system.
What is it connected with? Is it possible to periodically clean dangling descriptors?

Answer 1

Most likely, the point is in a poorly closed session and in the fact that the usual win 7 is limited in the number of simultaneous connections to the folder. Suppose the user opens the excel file filename.xls on the server, a temporary file ~$filename.xls is also created there. When this file is closed, all changes from the temporary file are overwritten into the original file, which is then automatically deleted. But it also happens that the file was closed and the temporary was not deleted, and when opening filename.xls, a file access error is issued (usually "the file is open by another user and can only be read"). You can manually delete them yourself, if such errors occur, you just need to set the parameter in the folder properties "show system files, hidden files and extensions for known file types". At least I have not seen automatic cleaners,
