I will try to finish it as soon as possible... I'm very busy... but i think i could add a "first" version at the end of this week with only basic help file. But, before giving too many hope... it's for Windows XP, with the framework 1.1 installed (if you do the Microsoft update often, it is already installed). In fact, it will do more than this... That's why it needs a help file: - batch convert P4 MAT files to P6 MAT files - manage the runtime preferences - organize/clean the runtimes and their references... - "material mixer": use other textures on an existing MAT file or Figure file by simple drag and drop - Create categories for any figure. - For any file (cr2, pz3, ..) you can save all the references to a folder for exporting. It works with compressed or uncompressed files, but doesne't support the external binaries.
