text: what is the difference between adobe acrobat and reader? i know this question has been asked before, but i would liek some detail.  i have a computer i bought second hand, with adobe acrobat 8 installed on it.  i also have adobe reader 7.0.5 on it, or maybe 7.0.8, not sure.  anyway, i would liek to free up some space, and i dont even know if i really need both or even either of these, especially if i use another pdf viewer, like foxit, which is much much smaller.... you don't say whether your "8" is the entire program or just the reader, but in any case it is a newer version than your old one; so delete the old one, you do not need both.  if it is the complete version, this lets you make pdf files, as well as read the files and i would keep it!!
