gzt: Task Scheduler > Microsoft\Windows\Data Integrity Scan.

I'd assume that would log a run at least but maybe not. Is there a command line exposed in that you can run manually and get some output?

You'd think...

gzt: Btw just noticed Microsoft removed ReFS creation from Pro standard at Fall Creators:

https://support.microsoft.com/en-us/help/4034825/features-that-are-removed-or-deprecated-in-windows-10-fall-creators-up

Creation is available in a new sku "Windows 10 Pro for Workstations" and up.

https://support.microsoft.com/en-us/help/4034825/features-that-are-removed-or-deprecated-in-windows-10-fall-creators-up

I saw something about that. Odd that they want it on servers but not workstations. They can't take it away entirely or disks would become inaccessible. I should probably migrate to NTFS, but unsure if storage spaces is worthwhile. ZFS would be best, but it's not worth running another server for files for me.

What's the file name, aux.jpg? It's nothing about integrity. AUX and CON are reserved names in Windows since MSDOS times and reside in device namespace rather than file namespace. You can delete the the device file by explicitly addressing the device namespace via the prefix \\.\, e.g.:

del \\.\C:\<your folder>\aux.jpg

Give @qwerty123 a cigar, that was the answer! The format of your command wasn't quite perfect (prefix \\?\ rather than \\.\) so I'll mark this as the answer to help others in future, but you had the concept exactly right :)

This command worked

del \\?\D:\path\to\folder\aux.jpg

I've found the Unlocker program works on all files I've encountered, including 'reserved' and 'system' files.
