To rename a file, you do not need to open the file in a program.
1.
Right-click the file that you want to rename, and then click Rename.
2.
Type the new name, and then press ENTER. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
You can also rename several files at once. If you give files of the same type the same name, each file will have the same name followed by a different sequential number (such as Renamed File (2), Renamed File (3), and so on). This can be useful for grouping related items. To do this, select all the files you want to rename, and then follow the same steps as you would for renaming an individual file. Each of the files will be saved with the new name, and a different sequential number will be appended automatically to the end of each file name.
A set of instructions that a computer uses to perform a specific task, such as word processing, accounting, or data management. Also called an application.

File
A collection of information that is stored on a computer under a single name. A file can be a text document, a picture, a program, and so on. Files typically have a three-letter file name extension that helps to indicate the type (for example, picture files are often saved in JPEG format and have the file name extension .jpg).
