MAPFool let you pre-process your map file before bringing it into Hammer 4.0 to perform several upgrade tasks, to make the amount of rework you have to do in Hammer a lot less. View the textures used in a map file, along with their frequency of usage.
The basic process is simple: Start MAPFool, open a map file, run some upgrades on it, then save the modified map file. Finally, fire up Hammer 4.0 and import the modified map file. You will now have a lot less rework ahead of you.
Note that your map must be in the MAP format (i.e., a structured text file with the .map extension) - MAPFool will not read the Hammer .rtf format. If you only have the .rtf files, you'll need to load them in an older version of Hammer and export them as .map files before you can use them with MAPFool.

MAPFool Features:
