Forum OpenACS Q&A: upload large file to a webdav server with built -in microsoft webdav client

I can upload 3Giga on my webdav server with microsoft built-in webdav client.
But I can't upload more than 3Giga. In fact at the end of operation, the size of uploaded file is less than the expected size.
When I try to upload file greater than 3Giga with another webdav client such as Bitkinex, I have not this problem.

Can you kindly help me to resolve my problem ?
Is it a windows patch to fix this problem ?
