I accidentally deleted some photos from a memory card. I recovered them using software called "Recover My Files". This software recovered the files but now I can't open them in CS3. I took these with an old Canon Rebel DSLR and they should not need converting, they opened fine before I deleted them. Any advice much appreciated. I really need these photos. Thanks.
It probabably means that the recovery software was not able to restore them to a readable form. Try opening in other programs (like Irfanview) and if you can open them do a "save as" and then maybe PS can open them.
Thanks, I ended up doing another recovery with PhotoRec freeware, it worked and I got all of the photos back. A bit tedious to use but free. I must have downloaded five or six recovery softwares but a lot of them can't retrieve raw files very well.
