'dirsize' is a simple perl script that displays the size of a given directory recursively... Now, I *KNOW* there must be some other way to do that but hey, it was faster writing down about 40 lines of perl...

diskover is a file system crawler and disk space usage software that uses Elasticsearch to index your file metadata. diskover crawls and indexes your files on a local computer or remote storage server over network mounts. diskover helps manage your storage by identifying old and unused files and give better insights into data change "hotfiles", file duplication "dupes" and wasted space. It is designed to help deal with managing large amounts of data growth and provide detailed storage analytics. See GitHub for requirements and instructions on installing.

A tool to verify and/or recover as much data as possible from failed disks. When a sector can not be read it will be filled with zeroes and diskrescue continues. The resulting disk/file can be checked with fsck and analyzed with dumpfs and fsdb.

This software is a distributed replicated blob server (inspired by the google file system paper http://www.cs.rochester.edu/sosp2003/papers/p125-ghemawat.pdf ). It stores your blobs ( <=> files) on a given number of your servers.

dl is a perl script which offers a quick solution to the difficulty of recovering deleted files in UNIX. Files given to dl are compressed, moved to a private directory, and deleted only when they haven't been recovered for a configurable amount of time.

These are scripts, that can be used to mount, umount and mkfs on files over the loop-device using dm-crypt for encryption.

This tool allows you to change the block size in ext2/ext3 filesystems keeping the data stored in them. Without a tool such as this, you need to reformat your filesystem to modify the block size.

e2undel is an interactive console tool that recovers the data of deleted files on an ext2 file system under Linux. It does not require any additional tools and should be useable without knowledge about ext2 interna.

e3compr (ext3 compression) provides transaprent, fast, low-level compression using ext3. Linux kernel 2.6 patch based on e2compr.

Operating system project from scratch to design and implement all components from boot strapping,hardware interrupts , memory manger ,file system , etc .

eMount is a free system administrator tool for Linux that can mount, encrypt and manage disk image files and physical disk drives. It relies on cryptsetup, which implements the LUKS disk encryption specification.

Experiments, etc. tools, frameworks for version control, business rules, persistence, code generation, etc. not an active project these days.

eXplode is a storage system checker. It contains a generic model checker for real code instead of abstract models. Using this model checker, eXplode can systematically check a storage system against many possible crashes to find crash-recovery errors.

easyBackuper is a program that allows users to easily backup files. Program supports windows and linux operating systems.

EFM is a simple console (VT100) file manager for embedded systems.

A virtual file system layer (VFS) that is portable and runs purely in user space. It provides an NFS v2 front end and a BSD-like VFS backend. Dynamic file system modules may be loaded to provide proxies, features or interfaces.

This modification of the ext2 kernel module allows to create files (cover files) whose block arrangement gets manipulated to represent a binary code, which can be extracted later. The information hiding approach used in this project was introduced by Khan et. al in 'Designing a cluster-based covert channel to evade disk investigation and forensics' (1st approach). Algorithm: When a cover file is written, an even blocknr. (for the 1st datablock) is choosen to represent a 0 or an odd blocknr. to represent an 1. For the remaining blocks of the cover file till the end of the code is reached, an adjacent blocknr. represents the same bit as the previous one and a non-adjacent blocknr. (a block will be skipped) a negated previous bit. It's necessary to use a partition with enough adjacent free blocks (code length + holes for fragmentation) within a blockgroup, for this algorithm to work correctly. WARNING: This is experimental software and could cause crashes or data loss!

ext2demo is user space utility for reading (also writing in the future) ext2 filesystem. I am writing it primary to learning the ext2/ext3 filesystem internals, but i hope it can be useful for others as well.

ext2hide allows users and administrators to utilize the reserved space of the ext2/3 superblocks to store hidden data on their filesystems, rendering it inaccessible to any normal viewing, yet still residing in permanent storage on disk.

The main goal of the ext3Viewer project is to give the user the possibility to explore the ext3 filesystem at a low-level. ext3viewer lets you study all the ext3 structures, and prints them in a more user-friendly form.

Ext3FS/Ext2FS File Recovery or Semantic File Carving tool.Recovers GIF/JPEG/MS-Word/PNG/HTML/JAVA/MP3 doc files<48KB if default block size=4kb.(if default size=8kb then recovers 96kb file)Identifying and recovering files based on analysis of file for

This is a patch to the ext3 file-system that implements asynchronous secure deletion.

exthide is a tool to hides files in ext2/ext3 File system.User can hide files under linux so that no one can see or access these files.User can unhide these file whenever he wants."This is a dangerous program".Use at your own risk :-)

Fam++ is a C++ wrapper for fam from sgi. fam can be found at http://oss.sgi.com/projects/fam/ fam uses imon to inform it when inodes change, the net effect being that applications can register interest in a file and be informed when that file change

Small tool written in Perl for synchronizing file archives based on MD5 sum comparison (e.g. it detects when a file has just been renamed or moved to a new location inside of the archive). Best suited for offline synchronization, e.g. for mp3 archives.
