We have a user who isn't able to transfer files from his C: drive to a SharePoint 2010 document library (through a Windows Explorer mapped network drive). He gets the following error message:
There is not enough space on [http:...]. You need an additional [...] GB to copy these files.
When he checks the mapped drive Properties through the Windows Explorer interface, he gets the same used/free space/capacity numbers as when he checks his C: drive properties - in this case it says he has 206 MB free space left. We don't have a quota on the SharePoint site, I was able to paste 500+ MB of files into the document library.
Why is there that error message in Windows Explorer? Why does the Properties of the mapped network drive show the same numbers as the C: drive?
