This is the basic feature without which ownCloud isn't particularly useful. Luckily, it's also the feature that works best and has had the most testing. Here's a screenshot of the web interface, which is the first method most people will use to add files. Notice the upload and new folder buttons.
Once you have some files there you'll probably want to able to get to them without having to go through the web interface, maybe on multiple platforms.
|Access from dolphin|
|Access from Finder on OS X|
|Make the desktop point to owncloud|
Again, everything I've shown here is done and works as advertised. There might be a few bugs left to be squashed but that's what bugs.kde.org is for. If you find them, please report them. Also, please start using ownCloud. There are some amazing features in the pipeline but we need more users and developers to make sure they all get completed. I'll leave you with a final screenshot of a feature that still needs a lot of work.P.S. If you're going to try ownCloud, please install from git. Master is very stable and easy to install. The owncloud wiki has lots of info on how to get it. Also, the number of people in #owncloud on freenode is growing quickly and it's a great place to get some help.
