Recover a deleted file or folder

When deleting a file or folder from your computer the best thing that I can recommend is to always think twice. Never delete any files or folders without taking that split second to reflect on the consequences. Do you really need to delete that particular file right this second. Of course many people also delete file accidentally so here are a few tips to try and recover them.

Recovery of a deleted file or folder depends on:

• Wether the file or folder went to the recycle bin

• Wether it is still in the recycle bin or has it been deleted from there also?

• How long ago did the file or folder get deleted?

• Has it been over written by other files?

Obviously the best scenario would be to have just accidentally deleted a file or folder and it is still in the recycle bin.

How to recover a deleted file:

1. Double click on the Recycle Bin on the desktop.

2. Then right click on the correct file and choose to restore it.
