Hi Zdenek,
Can you please describe the problem you are having? The folder you mentioned is not a "Panorama" type folder so you do not see a "Raw Data" tab where you can upload files. You will also not be able to see this folder in Skyline when you try to upload your documents to Panorama since Skyline only recognizes "Panorama" type folders. See this page for information on creating a folder: https://panoramaweb.org/doc_create_folder.url
Once you have the correct folder type you should be able to upload your raw data files as described on this page: https://panoramaweb.org/doc_upload_raw_data.url
I hope this helps. If not, please give us some more details so that we can better assist you.
Thanks,
Vagisha
