I am running an onsite TFS 2017 Build Server.
As part of my process, I delete all existing files in a target folder (using the Delete Files Utility).
This works almost every time, however, some sort of permission gets messed up on a file and this process is unable to delete it. Manually deleting the file from Explorer fixes things, but I would like to be able to delete files automatically using my build process.
I have checked and the TFS Service Account has has full rights to the file.
Here is the error

It's not always the same file that gets messed up.
