revCopyFile and revCopyFolder to the "desktop"

In the last line of this ..it does not look like you are naming a folder as
a destination.

The "folderToCopyTo" probably means 'folder' to copy to, not filename.

from the docs
The folderToCopyTo specifies the name and location of the FOLDER where the
copied file should be placed. If you specify a name but not a location,
Revolution assumes the destination folder is in the defaultFolder.

location = full path name /Users/jault/Documents/agreement.jpg
name = start with the default folder, thus nested.
/MyFolder/subFolder/ = defautFolder/ MyFolder/subFolder/

-----------------  further reading, esp error checking code
One tip for this:  most likely one of your folder variables did not look
like a folder or it has not been created yet, therefore setting the
defaultFolder was not possible, and it was not changed.

First
always put the path name into its own variable
and then put the filename into another.
Sometimes you will want the path or file or both.
Error checking is the main reason.

Then get in the habit of
 put specialFolderPath("DeskTop") into destPathh
if the last char of destPathh is not "/" then put "/" after destPathh

put destPathh & "MyFolder/"into sourcePathh
if there is not a folder sourcePathh then
answer "Oops!  There is no folder .." & sourcePathh
breakpoint
exit to top
end if

if there is not a folder destPathh then
answer "Oops!  There is no folder .." & destPathh
breakpoint
create folder destPathh
end if


put "MyFile.rev" into FN

put the defaultFolder into temp
breakpoint --be sure that it is where you think it should be

if there is not a file sourcePathh&FN then
answer "Oops!  There is no file .." & sourcePathh&FN
end if

revCopyFile (sourcePathh&FN), destPathh

if there is not a file destPathh&FN then
answer "Oops!  Did not copy.create file .." & destPathh&FN
end if
--------------------
another quick test method is to put this in the MULTI line message box

answer folder "pick a fat one"
put it & "/"

--> a full folder path will be returned

answer file "pick a crummy one"
put it

--> a full file path will be returned

------------------------------------
The way I do it does not use RevCopyFile or Folder
Same result, different form.

--for text files
put url ("file:"&pathh&FN) into url ("file:"&pathh2&FN2)
put fld 1 into url ("file:"&pathh&FN)
put fld 2 after url ("file:"&pathh&FN)
put fld 3 before url ("file:"&pathh&FN)

--for images
put url ("binfile:"&pathh&FN) into url ("binfile:"&pathh2&FN2)
-----------------------------------------------------------
Hope this helps with your designs
