S3QL is a file system that stores all its data online. It supports Amazon S3, Google Storage, and OpenStack and effectively provides you with a hard disk of dynamic, infinite capacity that can be accessed from any computer with Internet access. S3QL provides a standard, full featured Unix file system that is conceptually indistinguishable from any local file system. Additional features include compression, encryption, data de-duplication, immutable trees, and snapshotting, which make it especially suitable for online backup and archiving. The design favors simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection, error handling, and extensive automated test cases are provided.
fstransform is a tool to change a file-system from one format to another. For example, it can change from jfs, xfs, or reiser to ext2, ext3, or ext4. It works in-place and without the need for backup. It currently has been tested on Linux only. It uses a sparse file to create the new file-system image, moves all the files of the existing file-system into it, then remaps the sparse file to the original partition.
Weed-FS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files, and to serve the files fast! Instead of supporting full POSIX file system semantics, it implements only a key-file mapping. Instead of managing all file metadata in a central master, it manages file volumes in the central master and lets volume servers manage files and the metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers' memories, allowing faster file access with just one disk read operation. It is modelled on Facebook's Haystack design paper. Only 40 bytes of disk storage are required for each file's metadata, and disk reads are O(1).
QuickFind is a cross-platform Java application for searching files in your computer. Its sole purpose is to save user time by searching the desired file almost instantly. It is designed to support all of the major computer platforms. The user can schedule caching or manually cache at any time on selected directories. Once the caching is done, all you have to do is input the name of the file you want to find.
TOCC is a Tool for Obsessive Compulsive Classifiers. It implements a file system that uses tags instead of folders, allowing you to classify files however you want. For example, you could tag photos by location, people, and technique (e.g. black & white, HDR). Finding files is as simple as running a query like "give me all files tagged photo and my-love".
Collectfs is an easy-to-use FUSE userspace filesystem that provides add-on trash collection for any Linux directory hierarchy. Any file that is overwritten by removal (unlinking), moving, linking, symlinking, or open-truncation is relocated to a trash directory (mount-point/.trash/). Removed files are date-time stamped so that edit history is maintained. (A version number is appended if the same file is collected more than once in the same second).
stegfs is a Fuse based file system which provides absolute security. Using encryption to secure files, and the art of steganography to hide them, stegfs aims to ensure that the existence of such files isn't guaranteed. Implemented as a Fuse based file system and using the mhash and mcrypt libraries to provide the cryptographic hash and symmetric block cipher functions, stegfs is at the cutting edge of secure file system technology.
PHP MegaUpload.com Class is a PHP class that can send HTTP requests to the MegaUpload.com site Web server to perform several operations to manipulate files, folders, and accounts. Currently it can upload files, get the listing of files and folders, create folders, copy files and folders, edit file and folder details, delete files, send email, change account password, email address, Paypal account email address, retrieve or change account details, and more.
