Invoking the "Create Patch..." command when a folder comparison window is active will create a single patch file containing the patches for all pairs of different files, including added and deleted files, in that folder and all of its subfolders. For details on patch creation for single pair of files, see "Creating a Patch for a Single File Pair".
Use caution when executing this command as invoking it for large folders containing many pairs of different files may take a while.
