Finding the specific compression offsets needed to write custom file parsers or scripts. Quick Tips for Users:
Let’s walk through a real-world example: extracting hidden images from a mobile game’s assets.dat file.
Instead of typing offzip -a -1 bigfile.dat extracted/ 0x1A4 , a UI provides buttons, file dialogs, and sliders.
Scans any file (e.g., .dat , .bin , .pak ) to find and dump zlib/gzip/deflate data. It's a "brute-force" scanner that identifies where compressed blocks start and end.
function runOffzip(inputFile, outputDir, startOffset) let cmd = `offzip -a "$inputFile" "$outputDir" $startOffset`; exec(cmd, (error, stdout) => parseOffzipOutput(stdout); // Extract offsets and sizes );
