Abstract
The present invention provides an incremental upgrade method and system for a file. The method comprises: reading ZIP data information of an APK file, the ZIP data information being a ZIP data header and/or a ZIP directory table; acquiring an APK eigenvalue of the APK file according to the read ZIP data information; and performing incremental upgrade on an APK base file corresponding to the APK eigenvalue according to the APK eigenvalue. By means of the present invention, the efficiency of incremental upgrade can be improved while the calculation amount for acquiring an APK eigenvalue is reduced.
