How to use filesystem extention

I am trying to download a PDF, but get this error

'Directory_Exists' Action is incompatible with the 'FileSystem' extension definition. Please update it.

I saw something about "You can use the path returned by the .NET Path.GetTempFilename to generate a temporary file. "

I cant seem to get this right, what should i need to do

Hi Divan,

Please place your questions or comments regarding a specific Forge component on the components support page. The component team will be notified and are probably the best persons to answer your question.
