Files with no checked n version

Hi All,

Thanks in advance for your help.

I by mistake took ownership of all files with no checked in version on a library. Now all the files are checked out to my name. I lost the details whom they were originally checked out to. All the files were checked out to different users. How can I restore their check out to their previous values prior to myself taking ownership.

I need to restore it back to their names whom they were originally checked out.

Please help before being caught to client.

Thanks,
Vignesh Natarajan
