DON'T do a System Restore. That won't help, and may hurt your chances.
The solution isn't within Zoom Browser. You'll need a file recovery program. There are numerous free ones around, but my preferred tool for this kind of thing is (commercial) Photo Rescue Expert from DataRescue]DataRescue
. It costs a reasonable amount, but you can download the trial and run it against your card or disc to see what it says it can recover; if you're happy with that you can then pay to unlock the full functionality. Since your problem's strictly with deleted files and folders, not with a card or disk failure, it may be overkill and a free "undelete" utility may be sufficient.
First step - don't do anything with your computer or the memory card until you''ve downloaded (yes, that means using a different computer to do this) a recovery program or two to try. Install it on some kind of removable media, like a USB flash drive.
Second - while you're at that other computer, run the recovery program on your card(s). Anything it finds, you want to save on another drive, not back on your card. This minimizes your chances of stomping on part of one of the photos you want if you recover an older one first, by accident.
Third - now you're ready to run it on your main computer, against the hard disk where Zoom Browser moved the files. Same procedure - don't write recovered files back to the hard drive; write them to something else.
Good luck.
