Why am I receiving an error "The File is too large for the destination file system" when trying to upload a PHP file?
Windows Vista/7 x64
64 bit versions of Windows Vista implement a core WebDAV driver that has been shown to be incompatible with our servers. This results in failures attempting to upload files. It will be necessary to obtain a third party WebDAV client in order to allow your system to connect correctly to our servers. The following links provide information on products you may consider.
