Here is what I have from Sage on this, hope it helps.
TITLE :
What files hold public and private tasks in Sage MAS 90 and 200
DETAILS :
What files hold public and private tasks
Entry Type: Informational
Product: Sage MAS 90 ERP, Sage MAS 200 ERP
Application: Library Master
Version Reported: 4.20
Subject:
What files hold public and private tasks that appear on the My tasks tab?
Possible Resolution:
Private task data is stored in the Mnutasks.ini file which is found here:
..\Mas90\Launcher\Mas90Logon\WindowLogon\
Note: For Sage MAS 90, the Launcher directory is on the server. For Sage MAS 200, the Launcher
directory is on the workstation.
When you create a private task a directory is created for each Sage MAS 90 or 200 user and Windows
user combination. If a user logs on at a different computer and uses the same Windows logon and the
same Sage MAS 90 or 200 logon, the associated private tasks appear on the My Tasks tab.
Public task data is saved in Mnutaskp.ini which is found here:
..\Mas90\Mas_System\
