Lost Nano wallet without back up or private password

I transferred funds in Nano wallet in my OS X and started delegated harvesting about month ago. Yesterday I made Debian installation gone wrong and hardware is messed up. I made new OS X installation in external hardware. I used chrome when using The wallet and I have browsing history in use. Now I’m recovering the files from Mac to find user.wlt file. If I find it can I transfer it to external hardware and try it out ? Or does it possible have different name ?

If your browser is Safari, the backed up file name is “Unknown”.
In that case, please attach the extension “. wlt” to the file name “Unknown”.
Wallet will be repaired by you loading “Unknown.wlt” from NanoWallet.

Hi. Thanks for answering. I have been using Chrome as default.
What could the name be in that case ?
Disk Drill found this file: unknown_userUI.efires 251KB.

In Chrome, it will be output as “(Wallet name).wlt” file.
Try serch.

Thanks for advise. Tried few recovery programs but
could not find it, Got to be smarter next time.
