We often have a problem with uploading large files after new Foxweb installation.
Foxweb outputs an error: CANNOT CREATE POST DATAFILE
This occures because administrators install Foxweb under their own account and Foxweb often is running under another account (for security reasons).
But when Foxweb was installed it created registry key:
HKLM\SOFTWARE\Aegis Group\FoxWeb\CurrentVersion\TempDir
pointing to personal temporary directory of administrator who had installed FoxWeb.
Change value of this key to some more accessible folder and enjoy uploadig large files...
