Mapics Router History - scan or bonfire?

Hello all!
We have a storage area filled with cabinets filled with paper!  We are 
running out of room!
We have decided to have them scanned, as we are required to hold onto this 
data forever + 5 years by the FAA!   ;)
We are talking about 15,000 folders, 5 to 20 pages per folder.

Since our mfg order numbers are unique (MFA3450, MTZ5060, etc) I thought a 
network directory per MO, then within the directory
have each document related to the MO.  The MAPICS routers are between 1 to 
12 pages, there are also various certification
documents and typically an 11X17 drawing.

I don't see the need to index (read: software/database) or put much 
intelligence behind the names of the files,
ex:  within folder MFG3450, docs would be MFG3450-1.pdf, MFG3450-2.pdf, 
etc.

I plan to create a folder list, publish it in Integrator, include a button 
to open the directory for browsing & viewing.
We did the same for our mfg drawing quite successfully, approx 10,000 dwgs 
available in Integrator!!
We may be retiring that our old Oracle PDM system as a result!

Since this is rarely accessed historical data I wanted to keep it simple.

I was curious as to the thoughts or current experiences any of you have 
with this documentation dilemma.


Thanks in advance for your comments....james
