I just came across your extension today but upon trying it out it is not working for me. I select a file (or multiple), select Folderize and select ok (or check both optional files) and a folder with the correct name is created, the index is created but the files aren't moved into the folder. Additionally, the path in the index file isn't valid either...
Path
'./d:\FolderName\ProjectFolder\src\components\NewlyCreatedFolderizedComponentName';
I am running on a Win10 machine, with the latest version of VSCode
