Connecting to HiDrive with WebDAV (Windows 10)

The WebDAV protocol allows you to set up a network drive on Windows to access HiDrive. This article explains how to set it up and describes typical use cases.

Activation in HiDrive

To enable WebDAV in your HiDrive account:

  • Open the HiDrive web app in your browser.
  • Select Settings > Access rights and protocols in the menu bar.
  • Click on the pencil icon.
  • Activate WebDAV.
  • Complete your entries with Save.

Windows Setup

  • Open the Windows Explorer.
  • Click on This PC and go to the Computer tab.
  • Select Map network drive under the Map network drive drop-down menu. A new window opens.
  • In the Drive field, select the drive letter under which you want to mount your HiDrive.
  • Enter the address https://webdav.hidrive.ionos.com/ in the Folder field.
  • Make sure the Reconnect on sign-in box is enabled.
  • Confirm your entries with Finish.
  • Enter your HiDrive user name and your HiDrive password.
  • Complete your entries with OK. Windows Explorer opens with the newly created network drive.

Using the "net use" Command for the WebDAV Connection

You can use the net use command to create a WebDAV connection from the Windows command prompt. The following instructions are for Windows 10.

  • Click the magnifying glass icon in the menu bar at the bottom of the Windows screen.
  • Type cmd in the input box and press Enter to launch the Windows Command Prompt.
  • Enter the following command in the Windows command prompt:
    net use %driveletter%: https://webdav.hidrive.ionos.com/user:%username% %password% /persistent:yesReplace %driveletter%, %username% and %password% with your own details.
  • Confirm your entries by pressing the Enter key.

With /persistent:yes you ensure that the connection will be restored when the computer is rebooted. If you do not want a new connection, use /persistent:no instead. In this case, the connection will end as soon as you shut down the computer.

Fixing a Slow Connection

Certain Windows network settings can cause delays in accessing mounted HiDrive drives. The following instructions apply to Windows 10.

  • Click the magnifying glass (search) icon in the menu bar at the bottom of the Windows screen.
  • Type Internet Options and select the corresponding entry. A new window will open.
  • Select Tab: Connections > LAN Settings.
  • Uncheck Automatically detect settings.
  • Click OK.

Increasing the Maximum File Size for Downloads

The WebDAV protocol limits file sizes for uploading and downloading individual files. Under Windows, a maximum of 47 MB individual files can be downloaded via WebDAV by default. For larger files, you will receive an error message (Error 0x800700DF). This limit can be raised to 4 GB in the Windows Registry:

  • Click the magnifying glass (search) icon in the menu bar at the bottom of the Windows screen.
  • Type regedit.
  • Navigate to the following entry in the registry:
    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/WebClient/Parameters

  • Right-click FileSizeLimitInBytes.

  • Choose Modify.

  • Change the base to decimal and enter 4294967295 as the value. This corresponds to the protocol-dependent maximum size of 4 GB.

  • Click OK.

0-Byte Files

Files larger than 4 GB cannot be transferred via WebDAV. However, the file size check takes place only after the transfer process has started. If a file exceeds the size limit, the upload is aborted and only a 0 byte file is stored in HiDrive. Make sure to delete these files through the HiDrive web app.
