ABSTRACT:
Provided are methods, apparatus and computer program products for change management within a data processing system and in particular for simulating the effect of removal of a file from the system. An anti-file is created within a file system layer that is overlaid onto a set of computer program files. The anti-file hides a corresponding first file such that overlaying the anti-file layer on the set of program files simulates the effect of removing the first file from the set of program files.
