An A02 file acts as the third part of a broken-up archive and cannot open directly since it lacks the primary header, triggering errors like "unrecognized format"; instead, place all volumes together and open the starter—either the .ARJ if it exists or the .A00 otherwise—so tools like 7-Zip or WinRAR can automatically read A01, A02, and the rest, with extraction errors typically caused by missing, incomplete, or corrupted parts; confirming sequential filenames and matching base names ensures you’re opening the correct starting volume.
To verify what your A02 belongs to, alphabetically reorder the directory, then look for
identical prefixes—e.g., `backup.a00`, `backup.a01`, `backup.a02`—and check if a `.arj` file appears, which serves as the correct entry point; if there’s no `.arj` and the set starts at `.a00`, that’s the file to open via 7-Zip or WinRAR, and gaps in numbering or mismatched filenames signal missing or damaged segments that need re-copying or re-downloading before extraction succeeds.
Saying an A02 is "part 3" means it’s the next chunk after A01 in a multi-volume archive produced when large compressed files are split—most often into `.A00`, `.A01`, `.A02`—so A02 doesn’t hold standalone meaning but continues the same compressed stream, with the archive header stored in the first volume or a main `.ARJ`, making A02 unreadable on its own; when identical prefixes like `something.a00`, `something.a01`, and `something.a02` appear, the right method is to open the first piece so your extractor can automatically use the later parts.
An A02 file typically won’t open by itself because it’s a non-header segment in a split archive, and the critical metadata—archive header, index, compression specs, and integrity data—lives in the initial file like `.A00` or `.

ARJ`, so when you open A02 directly, the tool finds no header at the start and throws errors like "file corrupt", even though the set may be fine; placing all volumes in one folder and opening the first one is what allows the extractor to pull A02 and the rest in sequence.
When an archive tool "uses" an A02 file, it’s simply reading A02 as a continuation block rather than a separate volume, because extraction begins with the starter—usually the main `.ARJ` or `.A00`—where the header and index are stored, and once the extractor reaches the end of that segment, it automatically moves to `.A01`, then `.A02`, reading them as one continuous stream; if A02 is missing, renamed, or damaged, the process stops with errors like "unexpected end of archive".
