     Notes
     -----
-    - If `output_folder` is not provided (or is empty), the converted `.ims`
-        file will be written to the same directory as the input file.
     - The output filename is constructed by taking the input filename and
         replacing its extension with `.ims` (for example,
         `/path/to/image.czi` -> `/path/to/image.ims`).
