Exclude multiple file types in a single exclusion entry?

We have a lengthy list of files to exclude, so I would like to paste them into a single entry under the exclusions.  It seems to take them but I can't tell if it is actually working.  Should they be separated by comma or semicolon?  Is there a max number in a single entry?

Here is an example. 
*.3ds,*.ac$,*.apj,*.bak,*.ctb,*.cui,*.cuix,*.dcl,*.dst,*.dwf,*.dwg,*.dwl,*.dwl2,*.dwt,*.fbx,*.ipt,*.lin,*.ma,*.mat,*.max,*.mb,*.mns,*.mnu,*.pat,*.pgp,*.rfa,*.rft,*.rte,*.rvt,*.shp,*.shx,*.stb,*.sv$,*.sq*,*.wdp,*.ldb,*.mdb,*.mui,*.aux,*.chm

Thanks!
