Data Recovery 101
As deleted files have a rather short life expectancy under Windows, especially on the system drive where the paging file and many temporary files are located, you should normally attempt to recover an accidentally deleted file with TuneUp Undelete right away. The sooner you try, the better the chances that you will be able to recover the file.
Please do not install software for the recovery of deleted files on your computer when you have already deleted the file! When you install the software, you may overwrite the lost file forever. Even if you install the software on a different drive, temporary installation files may be written over the files you are trying to recover.
For this reason, data recovery software such as TuneUp Undelete should already be installed and operational. This way you have all the tools you need should something go wrong.
