When a large digital library or a high-resolution EPUB file is too big for a single transfer, it is often "split" into numbered volumes like .7z.001 , .7z.002 , up to .7z.014 .

: Ensure you have every numbered part of the sequence in one directory.

: Right-click the first file ( .7z.001 ) and select "Extract Files." The software will automatically pull data from part .014 to reconstruct the original EPUB.
