An A02 file is typically the part-three chunk of a split archive and cannot be opened on its own because it doesn’t contain the archive header, producing messages like “cannot read file”; the correct approach is to gather all matching parts and open the starting file—either the .ARJ or the .A00—so extraction tools like 7-Zip or WinRAR can rebuild the data by referencing A01, A02, and so forth; common failures point to missing volumes, truncated downloads, or corruption, and confirming that all filenames share the same prefix and sequential numbering ensures a clean extraction.
To figure out which set an A02 file belongs to, sort the file list by name so related pieces align, check for identical prefixes—`backup.a00`, `backup.a01`, `backup.a02`—and see whether a main file like `backup.arj` is present, which should be opened first; if no `.arj` exists and the sequence starts at `.a00`, that’s your starting volume, and you can confirm by opening it with 7-Zip or WinRAR, while any missing middle numbers or mismatched names mean extraction will fail until the missing or damaged parts are recovered.
Saying an A02 is “part 3” means it’s the third numbered segment 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 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 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 “CRC error”.
