My multi-purpose workbook has morphed into a monster and has slowed to less than a crawl.

Three sheets are used 90% of the time for user input and data manipulation.

The rest are mainly edited and needed right before printing.

I would like to break up the rest of this mammoth into categories such as:

1. Invoicing
2. Driver Records
3. Customer Info
4. Statisics
5. Ect...

Is it possible to link my information to these other workbooks without having to open them up?

Right now all info is linked sheet to sheet within the same workbook...

Would it be worth the trouble?

With Appreciation,
