As previously advised to use the command prompt to compact the back end,below is the actual patch where my BE is:
C:\Users\chris\Desktop\Data base 2016\IFRS\TestingC:\accdb
(1) What do I need to do to start compacting it?
(2) Will it not ask for the password to open it since it is password protected, temporally the compact close is still on in the back , this means that if I open it and close it, it will start compacting .
Kindly use the above path to demonstrate how it is done !
