I got this line working except that I need to copy the files to a folder (sitting in the container folder) whose name always ends with “Fonts” but always starts with something different.
copy (every file in folder originals_folder whose file type is FlTp_T1Fnt) to folder … of container of folder originals_folder
Does your containing folder only have one folder in it whose name contains 'Fonts"? If so try something like:
tell application "Finder"
set myFolder to first folder of (container of folder originals_folder) whose name contains "Fonts"
copy (every file in folder originals_folder whose file type is FlTp_T1Fnt) to folder myFolder
end tell
