If you have all parts of a split archive (e.g., part01.rar, part02.rar, ..., part06.rar), you can extract the entire archive by opening the first part with your extraction software. Most RAR extraction tools can automatically detect and use all parts to reassemble the original files.
To use the files within a RAR archive, you'll need to extract them. This can be done using software like WinRAR (for Windows), The Unarchiver (for macOS), or 7-Zip (for Windows).
Make sure every piece from .part01.rar up to the highest number (e.g., .part06.rar ) is in the same folder .
