If you don't want to use the EFT installation folder for temporary files or you want better visibility into your AS2 transfers, you can add the registry setting below to specify a location for files with AS2 POST requests for both the sending and receiving sides.
32-bit OS:
HKEY_LOCAL_MACHINE\Software\GlobalSCAPE Inc.\EFT Server 4.0\Config "AS2TempFolderPath" = path
64-bit OS:
HKEY_LOCAL_MACHINE\Software\Wow6432Node\GlobalSCAPE Inc.\EFT Server 4.0\Config "AS2TempFolderPath" = path
(If the path does not already exist, it will be created.)
