Step 1
Click the Windows "Start" button and select "Computer" to launch Windows Explorer.
Step 2
Locate the RAR files in Windows Explorer and make certain all the RAR parts are contained in the same folder.
Step 3
Double-click the first RAR part to launch WinRAR. The first part typically ends with ".part01.rar." However, if the parts follow the old naming pattern, such as ".r00," ".r01" and so on, double-click the file ending in ".rar." If double-clicking the first RAR part does not launch WinRAR, right-click the file, select "Open With" and select "WinRAR Archiver."
Step 4
Click the "Extract To" button to extract all files from the RAR archives. Alternatively, select individual files to only extract highlighted files.
Step 5
Click "OK" to recombine and extract files. By default, WinRAR extracts files to a subfolder of the folder containing the RAR file. However, you can enter any extraction location in the Destination Path field. Once extracted, you can safely close WinRAR and delete the RAR parts.
