You searched in all the folders on your PC, checked the ‘Recycle Bin’, and gone through the ‘Desktop’ as well, but you could not see an important file that you have stored before. Suddenly you wake up, find yourself in bed and realize that it was a nightmare. Many times, people face such troublesome situations in which they've accidentally deleted a precious file, or performed unexpected formatting of a volume due to a virus or malware infection.
The image below signifies the fractions of data loss and some potential reasons.
However, if you follow certain precautionary measures, you can better prepare yourself to face almost any data loss nightmare.
Maintain backup of your data: The best way to restore your data in any case of data loss is through a backup that you've created previously. It is a good practice to maintain a backup of your entire data on a regular basis so that you do not lose your latest documents files, photos, videos, songs, or other data of importance.
Cloud host your data: There are many free utilities and online options like Dropbox which can automatically synchronize all your data to the cloud and assure yourself that you'll never lose your data after a full system failure or crash.
Make sure that you are not deleting anything important: Many times, in order to clean up our cluttered hard drive space, we simply delete some really important files. Therefore, it is recommended to first ensure that you are not going to delete anything important or worth having in the future. For this, cross check whatever you are going to delete or put it somewhere else like on an external hard drive.
Empty the Recycle Bin with care: Cleaning up the ‘Recycle Bin’ also comes under the process of clearing your filled hard drive, but be vigilant while clearing out the bin. Many times users complain that they accidentally deleted a file that they want to restore from the Recycle Bin. Therefore it is suggested to watch what you are going to delete from your Recycle Bin before actually deleting anything from it.
