An A00 file is generally part of a multi-volume archive rather than a full package, used by systems like ARJ that broke data into A00, A01, A02, etc., alongside a primary .ARJ file holding the index, which is why opening A00 alone usually fails—it’s incomplete; proper extraction requires gathering every volume in the same folder, then opening the main archive so a tool like 7-Zip or WinRAR can process each piece in order, with errors such as "unexpected end of archive" pointing to missing or damaged segments.
If you only have an A00 file and the other pieces are missing, you rarely can extract anything meaningful because A00 isn’t a full archive—just one part of a continuous stream that must be followed immediately by A01, A02, etc., plus usually a main index file; when those are absent, decompressors can’t reconstruct the structure, so you’ll get "cannot open as archive" errors, and the only solution is finding the other matching pieces.
When we say an A00 file is "one part of a split/compressed archive," it means the compressed data was split into sequential volumes so A00 represents only the beginning fragment of one long data stream that continues into A01, A02, and beyond; these aren’t independent archives but interdependent segments that need to be read in sequence, typically created for size restrictions, and once all pieces are placed together, the extractor starts from the proper main file and merges them to rebuild and extract the actual contents.
An A00 file serves only as a segment of a multi-part archive rather than a complete archive, with the actual compressed stream continuing into A01, A02, etc., and the archive’s index or layout often residing in a main file like .ARJ; opening A00 alone leads to errors not because it’s damaged but because it lacks the rest of the stream, and it only becomes usable when all matching parts sit together and the extractor processes them sequentially.
An A00 file doesn’t contain all required data because split-archive formats slice one long compressed stream into sequential parts (A00, A01, A02…), and extraction depends on reading them in order; with only A00 available, decompression hits its end immediately and stops, and because the archive’s index or file list is often stored in a main file like .ARJ, extractors report corruption-type errors only because they lack the remaining pieces needed to reconstruct the whole archive.
A quick way to confirm what your A00 belongs to is to inspect it like a file hint, starting with nearby filenames: a matching `.ARJ` plus `.

A00/.A01…` means an ARJ multi-volume archive, whereas `.Z01/.Z02` with `.ZIP` indicates a split ZIP and `.R00/.R01` with `.RAR` signals an older RAR set, while `.001/.002/.003` often point to a generic splitter; if no main file appears, open the A00 with 7-Zip or check its header via a hex viewer, then group all similar parts and try opening the main or earliest file to see whether the extractor recognizes the archive or reports missing volumes.
