Will this work??
but as I know, microsoft Word cannot open PDF files 'cause i've tried it.
Quark? you mean Quark Express? I may try it out but i don't think Quark will free of charge...
so, is there any low-cost little app or something free to accomplish the merge? thanks everyone.
I've tried to open several files(including pdf, jpeg...etc) with Preview at the same time, but it cannot export all the stuff into one single file, no matter what file type. In fact, in Preview, i just cannot Select All pages.
