Does anybody have any experience of resolving the following message/problem when trying to transfer a binary file:
554 File Unavailable Transfer Aborted. File Type Incompatible. ?
I've Googled the error msg but can only find reference to the msg "554 requested action not taken: invalid REST parameter ?
Any assistance much appreciated. This is one of those tasks that I thought would take me 5 mins & has taken a day so far!?

Rgds, Mick
