There is not enough space on the disk on ASP.NET application

Question

I have the following setup on the Windows IIS machine with .NET 4.0 installed. 2 drives, C and D. The inetpub folder which contains my websites are on the D drive. My only web site saves the attachments to the D drive. My C drive has got no space on it (for arguments sake 0kb). Why would I get the following error when attempting to 'upload' attachments via the website to the D drive when the C drive is the one that's without space? Does .NET for example first copy it in a temp folder on C drive? Here's the error: ``` [IOException: There is not enough space on the disk. ] System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) +9718418 System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count) +9555882 System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count) +146 System.Web.TempFile.AddBytes(Byte[] data, Int32 offset, Int32 length) +32 System.Web.HttpRawUploadedContent.AddBytes(Byte[] data, Int32 offset, Int32 length) +8788874 System.Web.HttpRequest…

Accepted Answer

The temp folders used by your IIS is on C drive. That is the one causing this issue.

IIS is trying to write the files into the temporary files which is usually located under `C:\Windows\Microsoft.net\Framework\<version>\Temporary ASP.NET Files`
