Abstract
A system and method is disclosed for reducing a physical size of a data file that includes a plurality of blocks in sequence with each block having a defined size with a starting position and an end position. According to one aspect, the method includes obtaining information relating to an occupied physical region of the data file, where the occupied physical region contains unused space and/or unused data, and determining positions of first and second boundaries of the occupied physical region of the data file relative to the plurality of blocks in the data file. Furthermore, the method includes equalizing the occupied physical region by adjusting the first and second boundaries of the occupied physical region of the data file and removing data between the start and end of the removal region to reduce the physical size of the data file.
