Usually, files can be recovered. There are various
programs with different capabilities. Usually, these programs are expensive. "Undelete 4.0" has some freeware and shareware options. You can find a "more capable" (and more expensive) one at dtidata.com, called "recover it all".
Providing the files have not been overwritten, you can get them back!
I have deleted a folder (not realising). After this i went to the recycle bin to delete all the cookies i had put in there earlier and deleted everything in the recycle bin in one hit. Now i have just realised that this folder is missing. I think i have deleted it out of the recycle bin to. Is there any way of getting it back. I hope so! Please help asap. Many thanks Lucy.
