If you see a folder which may contain the file you need, then you can use file list sorting to search for it. Click with the left mouse button on the top of the column which you wish to sort. Clicking again with the mouse will change the direction of sorting.

Filters—are the simpliest way to find files by name, creation or modification date, size or status.

Files can be corrupted such that their names cannot be recovered. However, you may try to find them using file preview.
