Access

https://oc.informatik.uni-wuerzburg.de

If you do not have an account, look here.

Desktop Synchronization

Clients are available for several operating systems including Linux, Windows, Mac, Android, Apple-iOS. All clients can be downloaded from https://owncloud.org/ and please make sure you using the most recent versions.

Storage Space

Collaborators and students obtain 5GB usage space which can be extended when necessary. For more storage space, please write to admin@informatik.uni-wuerzburg.de

Sharing

You can share files, documents and folders with all users of the system. External sharing with non-users is also possible.

  • To make sharing with multiple users easier, we have implemented group-based sharing. This can be managed through the user portal where custom groups can be created as needed. Be aware that all members of this group need to have an account at the central services of the department of computer science.

WebDAV

Your files are accessible via WebDAV under the url https://oc.informatik.uni-wuerzburg.de/remote.php/webdav/

For more information see https://doc.owncloud.org/server/9.0/user_manual/files/access_webdav.html

Calendars

Importing

You can import calendars in ICAL/ICS format (you can export this file type from Google calendar, for example). Upload the ics file into Owncloud (as a regular file). When you click on it in the Owncloud file viewer you get asked into which calendar it should be imported.

Synchronize with Android

Android cannot synchronize with CalDAV/CardDAV servers without additional apps. I use DAVdroid (Android 4+ only), which works really good for me. It synchronizes your owncloud calendar with the local database on your mobile phone. So your appointments are shown in the regular calendar app.

DAVdroid can be purchased in Google Play for a small fee: https://play.google.com/store/apps/details?id=at.bitfire.davdroid&hl=de As DAVdroid is open source, it is also available on F-Droid for free: https://f-droid.org/repository/browse/?fdfilter=davdroid&fdid=at.bitfire.davdroid
The best way to get it from there is to install the F-Droid app (can automatically check for updates). Alternatively, you can also download DAVdroid as an Android package (*.apk) there. Anyhow you must configure Android to accept apps from "Unknown sources".

Enter the "Primäre CalDAV-Adresse" as path into DAVdroid, which you can find clicking on the gearwheel in the lower left in the calendar in the owncloud web interface.

You can change the color of the calendars on your local device (which are imported from owncloud on first sync) using this app: https://f-droid.org/repository/browse/?fdfilter=calendar&fdid=ch.ihdg.calendarcolor

Contacts

For synchronizing your contacts with other Applications, you need the CardDAV-Link of your ownCloud-Profile. Login to ownCloud, go to Contacts and click the "gear" icon at the bottom-left corner. Next to your address book, there is a button called CardDav link.

Thunderbird

In order to synchronize your contacts with Thunderbird, you have to download the SOGo Connector Addon. Download the newest .xpi-File and install it in Thunderbird via Tools | Addons. Click the "gear" icon at the top-right corner to the left of the search box and then Install Add-on From File.... After restarting, go to Tools | Address Book and click on File | New | Remoted Address Book. Paste your CardDAV-Link at URL. If you want to automatically add outgoing e-mail addresses to your ownCloud contacts, go to Tools | Composition | Addressing and change the address book accordingly.

Synchronize with Android

You can use DAVdroid for your contacts, too. See #Synchronize_with_Android. You need to configure two accounts in DAVdroid when you want to synchronize calendar and contacts.

Firefox Bookmarks

Note: This is not a recommendation, just an example. Feel free to use any app you wish and don't blame us if something goes wrong with Xmarks.

You can sync your firefox bookmarks using the app Xmarks (http://www.xmarks.com/) to our owncloud.

Open the Xmarks setup, then click on the Advanced tab. At the bottom of the window, tick the Use own server checkbox. In the Setup Own Server window, you need to enter the URL of a WebDAV file, e.g. https://oc.informatik.uni-wuerzburg.de/remote.php/webdav/bookmarks.txt
