If you read through the app logs, you can see how much free space there is
in each database. You should have informational messages like the one
below, where you can see I have 25 mb free in my public store.
Moving the databases and transaction logs is easy, although there's no
longer a utility that does it for you. See this KB for the procedure - just
observe ordinary precautions like having a good backup first. I didn't see
where this KB mentions moving the system logs - I recommend moving them at
the same time you do the transaction logs. Also, they mention in step 6
creating the same path on the new drive as exisited on the old - I recommend
that too.
