How much exists? There's nothing in the help file and /? only returns the -fs switch and the URL syntax.

Please, open your register (Start--> Run--> cmd) Please, enter: c:\program files\fdm\FILENAME.exe / to view the command line options.

CMD.exe is default Windows NT command interpreter, it opens text console window. To open registry you should run regedit.exe.

There is NO such path and file in standard FDM install, and there is missing option after slash.
It should be in 32-bit Windows:
or in 64-bit Windows:

In the answer you can see a message box containing short explanation:

---------------------------
Command line usage
---------------------------
fdm.exe [-fs] [-url=]url1 [-url=]url2 ...

-fs - force silent mode.
If url contains spaces it should be in quotes.

Example:
fdm.exe -fs "http://site.com/read me.txt"
---------------------------
OK
---------------------------

But the original poster already knows it and asks about more command line options. Do you know any undocumented command line option?

BTW. This FDM help is wrong. URL should NOT contain spaces, accented or special characters. They should be percent-encoded, see http://en.wikipedia.org/wiki/Percent-encoding

FDM requires a decent command-line support for most of the options available in the add download dialog.

For command line you should better use wget. FDM is not intended to run as a command line downloader.

Here are the silent install switches:I found this using Universal Silent Switch Finder (USSF) Enjoy, J.

There were NO question about install (fdminst.exe) options anywhere in this topic. Stop sending your misleading hints, please.
