[opencms-dev] How to upload multiple files and set content/file type?

[florimodo]

Hi, I have created xml files outside of OpenCMS and want to upload them
using the workplace tool. Unfortunately I can only set the file type of
the uploaded file if I upload a single file but not for zipped files. Is
there any possibility to upload multiple files and set their file type
in a batch mode using the workplace?
Thanks in advance!
