Abstract

We propose several pre-allocation size adjusting methods that can prevent the file fragmentation of files at arbitrary sizes depending on the growing file size. The proposed methods use small-size pre-allocation when the size of a growing file is relatively small and a large-size pre-allocation when the size of a growing file is large. We confirmed that the proposed methods effectively prevent not only internal disk fragmentation of small files (10s KBs), but also file fragmentation of large files (GBs).
