Need help moving Outlook folder

[JNR]

I'm using Outlook 2002.

My primary email account uses IMAP and I added it to
Outlook using <Tools> <Email Accounts ...> <Add a new
email account>.

I noticed that Outlook created a file for this account in
the directory:

C:\Documents and Settings\User\Local Settings\Application
Data\Outlook

This file obviously contains the email that has been
downloaded from my email account, since the file size
grows and shrinks as mail is added or deleted.

However, I would like to move this file from its default
location to another hard drive. The reason is that the
other hard drive is encrypted, and I want all my personal
data (including email) to be stored to the encrypted
drive.

I cannot figure out a way to move the file. If I go to
<File> <Data File Management ...> in the menu, I see the
email account and the file associated with it, in the
directory mentioned above. However, clicking on
<Settings> in the dialog box does not give me an option
to change the drive/directory for this file.

Is there some way to choose a custom location for the
file?

Thanks.
