Conversion of 7z.001 files to 7z file format

Pretty much like any other modern compressed archives even 7zip archives can be split to pieces in so called multi-volume archives. When needed, these pieces can be merged back to a single archive using any utility that supports 7zip formats, which is also the case of 7z.001 to 7z conversion - if you own all pieces.
