Requirement
For a proof of concept, users need to be able to upload files that are more than 500 MB. This is part of a plan to use SharePoint to replace redirected folders.
Problem:
Webdav has an inbuilt size limit of 50 MB. This limit is on the client side and nothing to do with SharePoint configuration.
Solution:
The limit can be changed by editing the registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WebClient\
Parameters\FileSizeLimitInBytes
Change the DWORD Decimal Value to file size specified in bytes, e.g. 2000000000 for 2GB.
Reboot.
*Note: There is a file size limit on a 32-Bit DWORD.
Testing:
Performed several tests before and after changing the DWORD value.
Before the change, copying a file to SharePoint would result in a time out even though the file size was within the limit defined in SharePoint configuration. After changing the DWORD value, I was able to upload multiple files ranging from 64 MB – 1.1 GB without any time outs.
