I use a camera on my motorbike as a safety measure but also use it for filming when at work.

So. Because I'm an absolute idiot when I went out earlier I deleted all the video files off the card to make sure I had enough space for video of the ride.... The video files I need for work from an event I ran yesterday.

Any suggestions on open source recovery software?

Preferably Linux but I can borrow a windows laptop if required.

Thanks for any advice!
