Cromfs 1.5.10

A compressed read-only filesystem for Linux.
Cromfs is a compressed read-only filesystem for Linux. Cromfs is intended for permanently archiving gigabytes of big files that have a lot of redundancy. It is more aimed at heavy compression than at a light fingerprint.

Main features:

  • Data, inodes, directories and block lists are stored compressed
  • Duplicate inodes, files and even duplicate file portions are detected and stored only once
  • Especially suitable for gigabyte-class archives of thousands of nearly-identical megabyte-class files.
  • Files are stored in solid blocks, meaning that parts of different files are compressed together for effective compression
  • Most of inode types recognized by Linux are supported (see comparisons).
  • The LZMA compression is used. In the general case, LZMA compresses better than gzip and bzip2.
  • As with usual filesystems, the files on a cromfs volume can be accessed in arbitrary order; the waits to open a specific file are small, despite the files being semisolidly archived.
