Problem description

WebDAV Direct Download utility is provided to download data of a user on legal hold. Because of default values for WebDAV in Windows 7 and later,  you may face issues during downloading through WebDAV.


The WebClient registry value FileSizeLimitInBytes decides the maximum size of the file which can be downloaded through WebDAV. 


Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved.


Customize the following registry entry to resolve this issue:

  1. Click Start, type regedit in the Start Search box, and then press ENTER.
  2. Open the registry editor (using regedit on the Windows Start menu)
  3. Locate and click the following registry subkey:

  4. Select DWORD FileSizeLimitInBytes.
  5. Go to Edit > Modify.
  6. In the Value data box, enter 4294967295 and then click OK.
    This sets the maximum you can download from the WebDAV to 4 GB at one time, where 4 GB is the maximum value supported by Windows OS.
  7. Exit Registry Editor and restart the Web Client Service.
