Make a new folder on your C drive.
Name it Recovery
Go to this site:
http://www.foto-erhardt.de/modules.php?name=Downloads
Download the free file: Digital Image Recovery in your Recovery folder.
The file will be Digital Image Recovery.zip
Once in your folder you need to "unzip" or "extract" this .zip file.
When you unzip or extract this .zip file select your Recovery folder for the
destination.
You will now have the file: 32fsu21.exe in this folder.
Double click on it to install the software.
Once installed you can change the language from German to English when the
software start.
Follow the directions on your screen after you start this software, very
easy to use and very good.
Maybe you never used a zip/unzip software. If so post again and I will find
a free one for you or just use google to find one.
Several available.
Whatever you do (there are also other softwares to do this that others will
suggest) use your computer as little as possible under you recover so that
you do not overwrite on these photo files.
