Moving files to folders - Bug or Limitation

Hi Folks,

I have a group of files such as:
- "Screenshot 2026-04-16 at 12.33.36.png"
- "Screenshot 2026-04-17 at 16.38.55.png"

I'd like to move them to a folder using the date shown within the file name (not the file created/modified timestamps).

I can setup a method using Replace and Add to generate new file names of:
- "2026-04-16/Screenshot 2026-04-16 at 12.33.36.png"
- "2026-04-17/Screenshot 2026-04-17 at 16.38.55.png"

However, I get an error ":/ is not supported in filenames".

Is this a product limitation or a bug? I'm using MacOS so is the tool incorrectly interpreting \ as a / or does it just not allow the output to split names into folder/names etc?

This is just a simple example, but should hopefully illustrate my issue. I actually want to do this for folder names rather than file names, and have much more complex requirements where I'm reordering parts of folder names and creating a structured folder hierarchy. I don't want to use a script to do this as I might as well have just written a Python app by that point, I'm trying to keep it simple and GUI driven. I can do this in Transnomino but that app only works on files rather than folders, so it's slow with lots of files and the file list gets rather unnecessarily cluttered making it difficult to verify the output path is correct.

Thanks.
