Yes, 1. Stop write anything to your finepix fujifilm, otherwise you will re-write the files and permanently loose your important data.
2. Use some data recovery software like this one. My friends recommend it to me, it works pretty well. And then scan your hard drive with the program, set a destination folder (folder where recovered files will be saved) somewhere on your computer. When the scan was finished, it will return a file list, you can choose the files you want to recover.
