An A02 file is generally just the third volume of a broken-up archive, not a standalone file type, and opening it directly won’t work because the archive’s header is stored in the first segment, leading to errors like "unknown archive"; the right method is to gather every piece, then open the starter file—either the main .ARJ or the .A00—so 7-Zip or WinRAR can pull data from A01, A02, etc., with issues like "next volume missing," truncated files, or CRC errors pointing to absent, incomplete, or corrupted parts; sorting the folder and verifying all numbered pieces match the same base name ensures clean extraction.
To verify what your A02 belongs to, sort files so related ones group together, 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.
Calling A02 "part 3" means it’s the third file in a sequential set, part of `.A00`, `.A01`, `.A02` file groups created for easier transfer or storage, and it’s not an independent format but a continuation of compressed data whose header lives in the first volume or `.ARJ`; when names like `something.a00`, `something.a01`, `something.a02` match, place them together and open the initial file so your extraction software can stitch A01 and A02 back into the original content.

An A02 file usually won’t open on its own because it’s just a middle segment of a multi-part archive, and formats store key information—headers, file lists, compression details, and checksums—in the first volume (like `.A00` or a main `.ARJ`), so opening A02 directly fails since it starts mid-stream without a recognizable signature, causing errors such as "cannot open as archive", even when the set is intact; the correct method is to put all parts together and open the starter so the extractor can read A01, A02, and onward automatically.
When 7-Zip or WinRAR "uses" A02, it’s reading it only as volume data, not opening it directly, because the archive header and file list come from `.ARJ` or `.A00`, and the extractor seamlessly steps from `.A00` to `.A01` to `.A02` during decompression; if the A02 piece is missing or corrupt, common errors include "end of archive reached early".
