Extracting part.rar files without previous volumes - TechRepublic

: All segments (part01, part02, part03, etc.) must be in the same folder for software like WinRAR or 7-Zip to successfully reassemble the original 5GB file.

: You typically cannot open part03.rar alone. Extraction must usually begin with the first part (e.g., 5GB.part01.rar ), which contains the archive's central directory or index.
