So if you've exported from Infinite Warfare you'll know the daunting process of separating the normal maps, ao maps, etc. from the tons of images that come with models.
 
So, since I like automating stuff, here's a tool to handle it. 

To use:
 
1. Group images into their own folders in a base folder with no other files/folders, like this. The folder
name will define the prefix of the images, i.e. weapon_fmg will result in weapon_fmg_n, etc.
 
2. Set the image format to write to in settings.ini (default is PNG).
 
3. Enter the directory of the main folder.
 
4. Let her do her job.
 
Notes:
 
* Accepts/Writes: TIFF, TGA, PNG, DDS*, JPEG
* Alpha channels are maintained for _CS.
* Potential for Access Denied Errors with files that already exist, so delete them I guess.
*DDS Cannot be written to.*
 
**While I do take suggestions, this tool was made for my needs and it does what I want it to do, I only released it as there's no point in keeping it to myself. If you want to modify the app, feel free, the Py file is there. Make a pull request if you have a suggestion.**
