annoying warning during synthesis.

Hi

I have just encountered another related issue. in my .qsf file some of my asignments looks like:

--- Quote Start ---

set_global_assignment -name SEARCH_PATH sub_dir/sub_sub_dir

--- Quote End ---

But some looks like:

--- Quote Start ---

set_global_assignment -name SEARCH_PATH "sub_dir/sub_sub_dir"

--- Quote End ---

When I try to remove the quotation marks, as soon as I switch back (I perform the change in a text editor) to the Quartus window I get a pop up error message saying something like:

"The qsf file was changed and contains errors, reverting to saved version"

Can anyone please explain to me what I'm missing here?

Found it - there was a space in the library name

This is a problem because I want to copy and paste from a project to a higher level project (after adding the first project path of course)

Thanks
