There are instances when files are accidentally deleted or moved to another location, particularly when you share the computer with multiple other users. The good thing is that there are several options you can try in order to locate lost files.
1). Click "Start," and type the file name or a part of the file name in the "Search" box. Files that match the keywords will automatically appear in the search results as you type. Click the file name to open. If you want to search files inside a particular folder, open the folder and type the file name or keywords in the "Search" bar in the upper right corner of the window. For more advanced searching, proceed to the next step.
