Upload fixPaths.ps1

Updates ComfyUI workflows searching and replacing for model files where the path is no w different, or a new model name is out. It runs recursively on all the files in the folder you specify, and before updating them, it will delete them to the recycle bin in case you need to recover them. Best to make a backup first.
