"Folder" in TouchDesigner always refers to a Windows or macOS operating system directory/folder system that contain files and other folders.

In contrast, a TouchDesigner "Path" is the hierarchy of Components internal to TouchDesigner. A Path is a location of a node, which may be a component containing other nodes.

Folders and filesystem paths are found in the operators that read files, such as the Folder DAT, Movie File In TOP, File In CHOP, File In DAT, Audio File In CHOP.

Filesystem files on the internet can be referred in TouchDesigner parameters by their URL:, which downloads the file and reads from the temporary local file.
