put URL destroys my file

[Tiemo Hollmann TB]

Hello,

Working with LC 4.5.4 I have a dmg file uploaded on my webserver. When
downloading it on a mac with a browser via ftp, the dmg keeps in good order.
But when doing

put URL pUrl into URL ("binfile:" & tFile) 

the format of the file seems to be destroyed and my mac thinks of it as
being a text file. The same procedure with a exe file on windows machine
works fine.

What do I oversee? Thanks for any hint

Tiemo
