Deleted files can be retrieved using data recovery software until they are overwritten, To ensure that they are permanently destroyed, you may full-format your disk or use a file shredding utility. Both will overwrite them with zeros or some "garbage" data.

How do you restore pictures you've deleted from a memory card on Windows Vista?

Files deleted from memory cards can often be recovered given the new files were not over written on the old files. If you accidentally deleted pictures from you memory card make sure you don't use the card for further storage so your files don't get overwritten. There are many free software available "zero assumption digital image recovery" is my favorite. Scanning your card with it will give you a list of recoverable files and you can choose which files you want to recover. I have recovered photos and videos deleted 2years ago from my phone's memory card with this method.

Any file being used cannot be deleted. Start the computer in safe mode and make sure there are no programs running. Use task manager to determine this. Stop all running processes. You then may be able to delete the virus. I would suggest you go to www.panda.com and get a free virus scan and removal.

How do you recover files from folder luck in Windows XP?

XP as such can not recover files from any folder if these files are deleted from the dustbin. There are however software available that can scan the index on the harddrive for deleted files and then recover these if they have not been overwritten. This software can in many cases also partially recover partially overwritten files. WinUndelete and Recovermyfiles are two choises. search via google. I am sure there exist many programs for this purpose, and some might even be free to use. Best of luck and regards.
