a few days ago i was editing a 300MB wav file using a program called wavepad . I needed to shut down the app to free up some ram. it asked me if i wanted to save changes, i said yes and it started to proceed very very slowly.

I decided that i didn't want to wait that long and it would be better to lose the small edits i had made and revert to the original. so i clicked cancel and wavepad imediately closed down - i am thinking it may have crashed or it may be a bug.

later i realized that the 300MB file was now only 65MB and it seems it has overwritten the original file with the same filename and i have lost most of the file.

I am trying to recover the file without much success - i would be most grateful for any help.

Hello, you can user data recovery software to recover lost wav file, I suggest you use data recovery wizard:  http://www.easeus.com/datarecoverywizard/index.htm

maybe, just maybe you could try to Grep the previous file from you cache file.

i have used it to recapture smaller files with success.
