error FTAM 5036

[Dubost_2]

I use the FTAM server ftam_resp to copy file across machines with the FTAM protocol.
When I try to copy a file named toto, everything goes fine. But when I try to copy a file named F1 I have the error :
FT5036 - Contents type inconsistent.
Document type simplification not supported (log_instance:9239, FTAM error_id 5036 = "Contents type inconsistent")]

Does anyone know what is this error ?
Why does it occur depending on the filename ?

Hi,

FTAM has strict file naming conventions based on content. Here's a list of FTAM document types:
