This small web app can be used to find files in any Saints Row PC game.
It lists all of the files that are stored in an unmodified set of packfiles for Saints Row 2, Saints Row: The Third, Saints Row IV and Saints Row: Gat Out Of Hell.
For each file it shows the ASM file that would need to be updated if you edit that file, and exactly what package files it is in - taking the guesswork out of updating ASM files.
Please report any bugs or improvements on the Saints Row Mods forum.
2015-01-22: updated for the first Gat Out Of Hell patch.
2015-06-19: added a popup that appears when you click on a package name - showing you the contents of the package.
