In addition to sorting, you can organize files by renaming them in a more orderly way. For instance, if the files all start with the same characters, they'll be easier to scan when sorted by name, for example: Murry Analysis, Murry Analysis (1), Murry Analysis (2), etc.. Windows gives you an easy way to rename a group of files with the same name followed by a number.
Select the files that you want to rename. Right-click one of the selected files and select Rename from the shortcut menu.
Now type a name for the group of files. Hit Enter, and the files will be renamed.
