Data security and WebDAV/Owncloud

On this website we provide several opportunities to get access to the WebDAV/OwnCloud platform for a secure data exchange within this project. WebDAV stands for "Web-based Distribution, Authoring, and Versioning" and is often used as an alternative to FTP (File Transfer Protocol). (At edacentrum the WebDAV service is provided as OwnCloud.) WebDAV/OwnCloud is like a remote hard drive and it can be used very similar to a hard drive in a computer. All transfers to the WebDAV/OwnCloud are secured by SSL encryption and a personnel login, which is your email address and a password. You may reset your password yourself at any time at with your email address.

There are basically three ways to access edacentrum's WebDAV/OwnCloud. We recommend the following methods in this order.

  1. ownCloud-Client download at
    Recommended, if you are allowed to install software with admin rights on your computer or smartphone.
  2. Web-Browser (read-write access for any browser - file upload!!! by Drag-and-Drop):
  3. Network-Drive (read-write access for Windows Vista, 7, 8, 8.1 and higher)
    We recommend to use drive letter “W:” if this is not used so far. You may use any other drive letter that is not already in use. You can do this without having administrative access to your computer. There are 2 alternative ways to connect to WebDAV using a drive letter which are described below in sections a)-b). Which one you use does not matter and depends on your or your computer's preferences.

    a) Execute the commands from the batch file manually
    Please execute the following code lines one by one in a Windwos command line interface (cmd or PowerShell). Press ENTER after each line. Please replace <LOGIN> by your e-mail-address.

    NET USE W: /DELETE 2>nul

    Now you can access the WebDAV at file://W:\<project name>. If this does not work, please try alternative c)

    b) Windows Explorer GUI
    • Open Windows Explorer
    • Right-Click on Computer
    • Choose "connect Webfolder" from the context Menue
    • Choose Letter for the drive
    • Insert directory:
    • IMPORTANT: ... choose "Use Other Access Data" (otherwise your windows login is used which has no meaning for our WebDAV)
    • finish
    • Then it takes some seconds ...
    • ... then an error message appears, which has to be ignored (Diagnosis or Close)
    • ... afterwards presse "Finish" again
    • ... then a login dialog appears which has to be filled in with user=e-mailadress and password
    • ... go on
    • ... if applicable insert the password a second time

edacentrum uses ownCloud as WebDAV implemention. You will find documentation at

There are also solutions for Linux and other operating systems at

Answers to further questions concerning the WebDAV you get here (German only) or by your project manager.
