A .C02 file is just a continuation segment in the sequence, and therefore appears as unrecognizable binary when isolated, because the controlling metadata is stored in earlier segments; the right approach is to place all parts in one folder and open the archive from C00 so the extraction software can process C02 automatically.

A .C02 file is meant to follow earlier parts rather than start them, so applications expecting signatures and metadata at the beginning find none, since those live in .C00; this causes "corrupt" or "unknown" messages even though C02 is fine, and such split sets routinely appear in massive archives, multi-volume backups, file-size-restricted transfers, and long-recording exports from CCTV/NVR devices.

In most workflows, the C00/C01/C02 pattern marks sequential pieces where each later file is continuation-only, so C00 is the entry point and C02 only has mid-stream data that depends on earlier volumes; this arises when backups, disk images, or large archives are divided to avoid size restrictions or to improve transport reliability, as well as in device exports like DVR/NVR systems, and you must always open or restore from the first part so the software can assemble the entire stream.

A .C02 file raises concerns when it’s found without matching C00/C01, because the first segments hold the entry metadata and C02 only contains continuation data; gaps like missing C01, mismatched names, renamed downloads, or an oddly sized part often point to an incomplete or corrupted set, and since the program originally sliced one continuous data stream into C00, C01, C02 and beyond, the pieces must be sequential and intact for restoration to succeed.

In that setup, C02 is unreadable alone because it has no header at its start, with C00 containing the necessary format signature, version info, and structural metadata; opening C02 directly produces gibberish, but when the full set is present and the process begins at C00, the software reconstructs the archive and consumes C02 smoothly as part of the sequence.
