FILE-BASED COMPRESSION ON A FAT VOLUME

摘要

Individual files within a FAT volume may be compressed while other files remain uncompressed. A FAT Compression Filter (FCF) intercepts calls to the file system, performs the compression and decompression tasks relating to the files on the FAT volume. The use of individual file compression with the FAT file system helps to ensure that the flash memory has a long life and does not quickly fail while still providing the benefits of individual file compression. The FAT Compression Filter allows individual files within a volume to be excluded from being compressed.
