How to Combine Parts of RAR Files

1. Download and install a compressed file management program, such as WinRAR or HJSplit for Windows or ChunkJoiner for Mac.

2. Place each RAR file in the same directory.

3. Open WinRAR or other compressed file manager.

4. In the main program window, browse to locate the directory where all the RAR files are stored. Double-click on the directory to open it.

5. Right-click on the first RAR file in the list and click 'Extract' to begin extracting the data stored in the RAR files. WinRAR and any other compression management software will automatically join the RAR file parts as long as they are all in the same folder.
