This function centralizes the logic for finding ComfyUI installations across different installation methods (standard, Electron app, portable, etc.) and provides a consistent way for other functions to locate model storage directories. The function checks multiple possible installation paths in order of preference and returns the first existing path. If no installation is found, it returns the most likely path where ComfyUI would be installed. .PARAMETER Subfolder The subfolder under the models directory (e.g., "checkpoints", "vae", "loras"). Defaults to "checkpoints" for standard diffusion models. .PARAMETER ReturnAll witch to return all possible model paths instead of just the first existing one. Useful for functions that need to search across all possible locations. .EXAMPLE $modelPath = Get-ComfyUIModelPath Returns the path to the checkpoints directory for the current ComfyUI installation. .EXAMPLE $vaePath = Get-ComfyUIModelPath -Subfolder "vae" Returns the path to the VAE models directory. .EXAMPLE $allPaths = Get-ComfyUIModelPath -ReturnAll Returns all possible model paths for comprehensive searching. #> function Get-ComfyUIModelPath { [CmdletBinding()] param( ####################################################################### [Parameter( Mandatory = $false, Position = 0, HelpMessage = "Subfolder under models directory (e.g., checkpoints, vae, loras)" )] [string] $Subfolder = "checkpoints", ####################################################################### [Parameter( Mandatory = $false, HelpMessage = "Return all possible paths instead of just the first existing one" )] [switch] $ReturnAll ####################################################################### ) begin { #
