It is perfectly human to make errors and data loss is something which never happens with a prior warning - you will never know when it might hit you.
There is no need of blaming yourself, your kids or your friend for mistakenly deleting a vital file on your machine.
This will change nothing but create contempt.
However, all is not lost as you can still recover the file.
When a file is deleted from the system, using the normal delete command, it is never moved to the recycle bin as we all think.
The only thing that happens is the change of registry directory entry with the file icon appearing on the recycle bin.
If you check your disk space, you will realize that nothing has changed; the file still uses the same space.
Moreover, after deleting the file further by emptying the recycle bin, it still remains.
The system frees the disk space but still keeps a copy of the file.
However, it is overwritten if case the operating system needs more space.
This is the principle that the file recover software applies to get the file back to you.
However, you have to be fast else the operating system overwrites the file.
The work of the recover files software is to search the operating system for deleted files and rebuild them using the directory on the operating system.
The software also searches for lost partitions and recovers the data from them by accessing the drive, analyzing it for deleted files, locate them and display them in a method that you can use to resave them on your preferred safe drive.
There a few precautions that you should take after mistakenly deleting a file.
Never open or close files or applications; doing this creates temporary files which might overwrite the deleted files or corrupt them.
Moreover, when installing more software, do not run it on the drive that contained the file.
Recover files software is easy to use and the installation process is easy.
After the installation, double clicking on the shortcut to run the software.
Select the drive that contains the deleted files and click next.
The scan will be executed and a list of recovery files will be listed with reference to their route folders.
The final step is to select your files of interest and save them on a safe drive of your choice.
