can not delete, move or open file

I have windows 10. I have word 1026 file that when I try to open it wont open, I just get the "word not responding" message and have to restart the computer to get out of it. I can not delete the file or move it. My back up script gives me an error message that it out the file same file.

I have tired to delete the file in safe mode with same results as above. I downloaded an unlocker program and it says file can't be unlocked. I would like to get rid of this file. I am aware of it everyday when my backup script report says there was an a error with this file ad it could not be copied to my backup drive.

any suggestions would be appreciated
