Ever wondered how big a Designer project would be, disk wise, if you had
only Packages in it?

So I made an D4.01 project, all that is in it is one Identity Vault
(need it, set to IDM4 to get the Package Catalog option), and imported
all my packages. (I have some extras, like Lothars driver, and some
custom ones I have built, but maybe 20 extra packages total. There are
well over 100 packages by Novell, so this should not greatly affect it).

Guess how much disk space it took?

Winders 7 reports:
68.8 MB, 95.6 on disk (Due to bajillions of tiny files not filling a
full sector/block in the filesystem).

9,339 files, 1,102 folders!
