AUC: Application Unicode Object Cache file - (as of AX 4.0) This file is created on the client side, and is used to improve performance by caching AX objects. When you are in the situation where an AX client keeps using ‘old code’, or where something works on one client and not on the other, removing the AUC file might be the solution. You can find this file in the directory C:\Documents and Settings\[USERNAME]\Local Settings\Application Data for xp, or C:\Users\USERNAME\AppData\Local for vista.
AOC: Axapta Object Cache file - (Until Axapta 3). This is the ‘old’ version of the AUC file but serves the same purpose.
