Hi Everyone,

i use the perxpective theme endpoint of the api.

I want to ask if it is possible to PUT a new File to an existig Theme, but the file is in a subfolder.  
Like this:

I tried to url encode the filename with %2F.

Is there something wrong how I use it or is it not possible to add files in subfolders?

Thanks
