For Seniors: Rename a Windows File or Folder
If a file is hard to identify, rename it. Likewise, rename folders if their purpose has changed or is hard to identify. By renaming Windows files and folders when needed, you can often make it easier to find them when you want to use them.
Right-click Start, choose Open Windows Explorer, and then browse to find the file or folder you want to rename.
As you double-click each folder, the folder's contents is displayed. Eventually, you will dig far enough to find the file or folder you want to rename.
Right-click the file and choose Rename.
The file or folder's name is highlighted to show that it's available for editing.
Type a new name, and then click anywhere outside the file or folder.
The file or folder is saved with its new name.
You can’t rename a file to have the same name as another file located in the same folder. To give a file the same name as another, cut it from its current location, paste it into another folder, and then follow the steps here. Or open the file and save it to a new location with the same name, which creates a copy.
Be careful, though: Two files with the same name can cause confusion when you search for files. If at all possible, use unique filenames.
