A technique for creating dynamically attachable and detachable binary files is provided. The invention provides an efficient mechanism to manage the existing code bases with respect to the additional code needed for a particular feature as a single code base. It also provides a mechanism for designers to plan for such features even before the code is conceptualized. The system parses the code having a dynamic feature manager (DFM) tag to produce a base code wherein the DFM tag encloses a feature. The multiple code sets based on the DFM tags are created. A feature change table storing the information about a changed feature compared to the feature from the code sets is generated and stored in the system. The code sets are then compiled to generate binaries. The difference between each of the binaries, using the feature change tables is determined and stored which is used for creating differential binary file(s).
