An A02 file is simply part three of a split compressed file and cannot open alone since the main index is stored in volume one, which is why direct attempts show errors like “bad archive”; to extract properly, all volumes must be together, and you open the starter—either the .ARJ file or, when absent, the .A00—letting 7-Zip or WinRAR automatically chain through A01, A02, and the rest, while failures like “next volume missing,” “unexpected end,” or CRC problems indicate missing, incomplete, or corrupted pieces; checking filenames and ensuring no skipped numbers usually reveals what A02 belongs to.
To quickly confirm what an A02 is part of, organize the list by filename so matching pieces line up, look for the same base name across files—`backup.a00`, `backup.a01`, `backup.a02`—and check for a main starter such as `backup.arj`; if it exists, you open the `.

Describing A02 as “part 3” means it belongs to a multi-volume archive produced when a big compressed file is divided into `.A00`, `.A01`, `.A02`, etc. for easier transfer or storage, so A02 itself has no separate meaning and continues the same data, while the header and index live in the first volume or a main `.ARJ`, making A02 alone unusable; seeing matching files like `something.a00`, `something.a01`, and `something.a02` indicates a split set, and opening the first piece lets your extraction tool assemble the full archive.
An A02 file rarely opens directly because it’s a mid-volume fragment in a multi-part archive, and the defining information—archive header, directory listing, compression settings, and checks—resides in the first segment, so programs scanning A02’s start find no signature and raise errors like “unrecognized format”, even though the set may be complete; placing every part together and opening `.A00` or the main `.ARJ` allows the extractor to use A02 automatically while rebuilding the archive.
When an archive program processes A02, it’s simply consuming it as the next part, since extraction logic starts with the first chunk that has the header, and the tool automatically chains through `.A01` and `.A02` as the data stream requires; if A02 isn’t available or is damaged, the extractor stops and reports errors like “unexpected EOF”.
