at System.IO.__Error.WinIOError(Int32errorCode, String maybeFullPath) at System.IO.File.Delete(String path)

at secure.course.ContentList.ListCourses.imgBtnExport_Click(Object sender, ImageClickEventArgs e) in secure\course\ContentList\ListCourses.aspx.cs:line 1639

above is the stack trace for the error which i am getting while Deleting a Zip 开发者_JAVA技巧file.

The process cannot access the file 'content\temp\Courses\MSOf­ficeExcel2007MSOE2007.Zip' because it is being used by another process

Well, it sounds like MSOfficeExcel2007MSOE2007.zip file is in use and cannot be accessed. If you are accessing it in your code, you'll want to close it before you try to delete it. If you aren't accessing it in your code, make sure you don't have another program with it open (IE - you checked the contents of the .zip file in WinZip and didn't close it)

Make sure you have Full control permission on that folder.
