Then maybe check registry
HKEY_Classes_Root\fndfile\shell\open item.

I just did. I assume that the "ddeexec" entry is used, as the "command"
entry does not show any parameters.

But, as you now have put my eye on it, do you have any idea what
[OpenFindFile("%1", %I)] does ? "%1" is ofcourse the .FND file, but "%I"
? (a quick google didn't turn up anything).

I don't know what "ddeexec" entry is for and its syntax. In my
experiment it is necessary for fnd file to function. My "ddeexec" entry is:
-------------------------------------------------
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\fndfile\shell\open\ddeexec]
@="[OpenFindFile(\"%1\", %I)]"

[HKEY_CLASSES_ROOT\fndfile\shell\open\ddeexec\appli cation]
@="Folders"

[HKEY_CLASSES_ROOT\fndfile\shell\open\ddeexec\topic]
@="AppProperties"
-------------------------------------------------
Deleting any sub-entry will cause error.
