Cause 3: File system corruption is preventing access to the file
You may not be able to delete the file if the file system is corrupted. To resolve this issue, run the Chkdsk utility on the disk volume to correct any errors.

Bad sectors on the disk, other faulty hardware, or software bugs can corrupt the file system and put files in a problematic state. Typical operations may fail in a variety of ways. When the file system detects corruption, it logs an event to the event log and you typically receive a message that prompts you to run Chkdsk. Depending on the nature of the corruption, Chkdsk may or may not be able to recover file data; however, Chkdsk returns the file system to an internally consistent state.
