How to Find Out Which Windows Process is Using a File

Ever come across the following messages and wondered how to find out what is using the file?

• Cannot delete file: Access is denied
• There has been a sharing violation.
• The source or destination file may be in use.
• The file is in use by another program or user.
• Make sure the disk is not full or write-protected and that the file is not currently in use.

I found a neat utility that allows you to find out

Process Explorer v14.01 shows you information about which handles and DLLs processes have opened or loaded.
