So who on earth would want this turned on? You, if you’re a

programmer or system administrator and you’re worried that the
indexed version of the system files might be out of date. (That
happens, since system files change often, and the index may take
some time to catch up.)

Include system directories. When you’re searching a disk that
hasn’t been indexed, do you want Windows to look inside the

folders that contain Windows itself (as opposed to just the
documents people have created)? If yes, then turn this on.

Include compressed files (ZIP, CAB…). When you’re searching
a disk that hasn’t been indexed, do you want Windows to search
for files inside compressed archives, like .zip and .cab files? If yes,

then turn on this checkbox. (Windows doesn’t ordinarily search
archives, even on an indexed hard drive.)

Always search file names and contents. As the previous pages
make clear, the Windows search mechanism relies on an index—an
invisible database that tracks the location, contents, and metadata

of every file. If you attach a new hard drive, or attempt to search
another computer on the network that hasn’t been indexed, then
Windows ordinarily just searches its files’ names. After all, it has

no index to search for that drive.

If Windows did attempt to index those other drives, you’d
sometimes have to wait awhile, at least the first time, because

index-building isn’t instantaneous. That’s why the factory setting
here is Off.

But if you really want Windows to search the text inside the other

drives’ files, even without an index—which can be painfully slow
—then turn this checkbox on instead.
