LispWorks requires about 30MB for 32-bit and 50MB for 64-bit to install without documentation and optional modules. Installing the documentation adds about 110MB and the optional modules about 15MB. A full installation of the 64-bit Enterprise Edition with all documentation and optional modules requires about 175MB.
The Professional/Enterprise documentation includes printable PDF format manuals. You may delete any of these that you do not need. They are available at
in any case, and the same manuals are also available there in PostScript format.
