that may work. all of the files i don't need to link to, all have at least
one space in the file name. the ones i link to, are all continuous to the
file extension. a couple may have an underscore in the name, but no spaces.

well, ok. If you can not group your files in a reserved folder, you may
add a specific mark in their names.

Example name becomes _SYNTH_name.cls or name_MARKER.xls
or anything of your choice.

Then there's a difference with other books.

for example when reading the names, just check that
left( filename , 6) = "_SYNTH_"
