Structure scan
In addition to signature scanning, the contents of every map zip were classified file by file:
| Type | Count | Purpose |
|---|---|---|
| .ufo | 289+ | Map archives (HPI format) |
| .txt | 150+ | Map info / readmes |
| .jpg/.bmp/.gif | 179+ | Minimap previews |
| .rtf/.html | 10+ | Documentation |
| .exe/.dll/.bat/.vbs | 0 in map zips | — |
Not a single executable file inside the map zips — maps conceptually cannot execute code. The only executables ever hosted were the original Cavedog installers (Win16, from Cavedog’s own FTP server, ~1998), which are no longer publicly distributed.
