To upload a file using the admin, go to files, click on Upload File on the top right corner of the page.

You will be prompted to fill in the path, select the files and choose if you want to allow public access to the files.

Folders can be created while uploading your files, to create them, just add forward slashes in it.
If you want to create a folder called images and a folder called icons inside, just type images/icons.

Select the files that you want to upload.

Choose if you want to allow public access, you can do that later if needed.

Public Access means that if you share your file's URL with someone, they will be able to view your file. If it's private, only you logged at TagoIO will have access to it.

Click Upload and your files will be uploaded to TagoIO
