How to recover btc after windows reinstall

[NotATether]

It's Windows so your bitcoin wallet should be in the AppData/Roaming/Bitcoin/wallets folder.

When I reinstalled Windows (8.1) one time, it saved my home folder along with the rest of the old Windows system inside the C:/Windows.old.<number> folder, but it deleted that folder after about 30 days. I don't think every reinstall will do this, so if you have that folder on your system, check there first (and make sure "Hidden Files and Folders" setting is on in File Explorer so that you don't miss it).

Thank you for you quick response. Also my hdd disk image is around 300 Go and when i launch a search using whexeditor it crashes after a few hours do you have any  better software or other way to do this job ?

I don't use whexeditor so I can't suggest a possible solution but pywallet's --recov tool may work.
