Knowledge about the process of retrieve deleted files in windows allows for recovery of important documents, pictures, and other types of information which have been accidentally deleted. First of all, one should try to open the Recycle Bin and recover their data if it is still available there. Otherwise, one might want to check for a previous version of the files, either from File History or other similar services, and OneDrive as well in case the files have been uploaded to the cloud. Windows File Recovery tool, as well as other similar recovery programs, can also be useful in finding traces of the lost files. One should not install such software on the same drive where the data was lost.
