Textures, general batch resize. (And possible format change)

toxsickcity

Hi. I have a small library of content. When I explore the library in windows explorer the textures folder is near 35GB. For my portable laptop that's a big chunk of the SSD! Keeping files on a external drive is not ideal! I would love to know some answers or comments about my questions below. I am looking for easiest ways to accomplish this. 1. regarding file formats I can see BMP and TIFF are largest file size. Can I change them to JPG? Or would DAZ3D report them missing and objects show up without textures? 2. If I use a photo manager to find and resize any image larger then 4096x4096.. and bring them down to 4096x4096. (I might even bring them down to 2048x2048) Would changing the resolution cause Daz3D to display the texture incorrectly? Do the models have information on texture resolution which would need the texture to be a certain resolution? Do you guys have any other ideas? P.S I already run NTFS compression!
