3. Select or highlight the file that you want to split.

4. Right click on it, then click on "Add to archive..."


5. In the dialog box that appears, the archive format is set to RAR by default, and the file name is appended with .rar. You can keep these default settings. (You can choose between RAR and ZIP. )

6. In the "Split to volumes, bytes" section, you can pick the categories there to split the file into pre-defined sizes like 700MB or 4481MB . But you can also specify your own file size in MB. In this example, we enter 20MB.


7. When you click on OK button, the compression and the splitting of the selected file will proceed like this screen shot:


8. When the process is completed, all the smaller files will be stored in the same location as the source file, the one that you split into several files. Also, these smaller files are numbered  appended with "part" in the filename. Here is my result with the 601MB file being split into 32 smaller files:
