<p>A method for managing access to add-on data files (4) having an add-on data file attribute, which is used by a software application (1), is presented, comprising the steps of: monitoring input /output commands of said software application to an application programming interface (API) of code layer (Sl) to determine whether an access to a data file with said add-on data file attribute is requested by said software application (S2); checking whether an access code for said add-on data file (4) is present in an access code list related to said software application if at least one of the monitored input /output commands request access to said add-on data file (S3), if said access code is not present in said access control list, retrieving said access code from an external source outside of said access control list (S4); providing access to said add-on data file (4) (S5) if said access code is present. A corresponding system is presented as well.</p> |
