There is not enough space on davwwwroot when pasting

I am trying to paste 5GB into a library through the Explorer View Unfortunately, I get this message:

There is not enough space on davwwwroot. You need an additional 2,06 to copy the files.

I am using SharePoint 2013. I have already tried the following:

• I have checked that I have enough space on both the Sql Server and Front End machine. Limit site storage in Central Administration is not checked Increased requestLimits maxAllowedContentLength to "6147483647"

What else could I do?
