You can switch between 'Photos' and 'Albums' view. If you select a photo, the image library will be closed at once.

If you select a video, you will have to submit it by tapping 'Choose'.

Next, you have to choose the target folder. It depends on your upload rights, which folders and subfolders are available for you (please ask your admin for your rights)

You can filter the target folder list by keyboard search and/or select it by scrolling the list and tapping the target folder.

The last step is entering a filename. (You don't have to set the suffix like .MOV or .JPG. The suffix of the original file will be used.)

The UPLOAD button will appear. Tap it!

You can view the upload progress in MB and percent. If you want to cancel the upload, please swipe to delete. You can also pause & resume your upload by clicking the pause/resume button on the right side of your download.

If you select the next upload while still uploading, the new one will be queued and starts automatically, as soon the other one is finished.

The upload will also be processed when switching to another app, if you set the Background processing setting according to this article.
