How to trick NTFS file locks when nothing else works:

I recently had a big problem with a huge amount of files that were locked in a read-only state.
No software on the internet solved my problem.
It was impossible to remove the read-only attribute on them.

Finally I came up with an idea:

Take a USB-disk, format it with FAT32 and copy the files.
Then use the attrib-command to remove attributes.

Code:

attrib -r -s -a -h /S /D <path>



Copy the files back to their original place.

Hope it can save someone elses valuable time.
I just spent 8 hours of troubleshooting.

The lock was only stopping me modifying the files, not the location of the files.
So moving or copying them to the FAT32-partition was no problem.
With the Domain Admin account I was able to delete the original files and copy the ones on the FAT32-partition back.
