DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, Sun audio for samples, etc.). Conversely, when it reads files for inclusion in pwads, it does the necessary conversions (for example, from PPM to Doom picture format). In addition, DeuTex has functions such as merging wads, etc. If you're doing any wad hacking beyond level editing, DeuTex is a must.

WADptr is a utility for reducing the size of Doom WAD files. The "compressed" WADs will still work the same as the originals. The program works by exploiting the WAD file format to combine repeated / redundant material.

dxflib is a C++ library mainly for parsing and writing DXF files.
