Bug: Can't use "Send to printer" for non-existing directories

[Lichtjaeger]

If I use "Send to printer" in PrusaSlicer to upload a file to my SL1S, I am also offered to write to a folder path. When I try to write to a non-existing path, I will get an error message.

So currently, I can only write to the root and the samples directory because I don't know how to create new directories.

I assume the printer should create non-existent folders first and then write the file into them instead of just throwing errors.
