A little heads up – M3 UI Adapter 10.3.0.0 moves much of the mne\ directories into either a Postgres or MS SQL database.
Looks like the JScripts move in to the database too.
See the ISOAG_10.2.1_W.pdf (Smart Office Admin guide page 119, and M3COREAG_13.3.0_W.pdf (M3 Core admin guide around page 112)
