Estimating File Compressibility Using File Extensions
… systems were designed with the assumption that files with the same filename extension will compress roughly to the mean compression ratio (the ratio of compressed size to original size) of some set of files with the same extension. This implies that the compression ratio distribution follows a …

Efficient file distribution in a flexible,wide-area file system
WheelFS is a wide-area distributed file system designed to help applications cope with the challenges of sharing data over the wide-area network. A wide range of applications can use WheelFS as a storage layer because applications can control various trade-offs in WheelFS, such as consistency …

Improving block sharing in the Write Anywhere File Layout file system
It is often useful in modern file systems for several files to share one or more data blocks. Block sharing is used to improve storage utilization by storing only one copy of a block shared by multiple files or volumes. This thesis proposes an approach, called Space Maker, which uses garbage …

Generating Log File Analyzers
… Programs often store some of their outputs in files known as log files. The task of evaluating test results can be automated by using a log file analyzer. The main goal of this thesis is to design an approach to generate log file analyzers based on a set of state machine specifications. Our …

The Jade File System.
File systems have long been the most important and most widely used form of shared permanent storage. File systems in traditional time-sharing systems such as Unix support a coherent sharing model for multiple users. Distributed file systems implement this sharing model in local area networks. …

Pragmatics of File Migration
File migration is the movement of files from secondary storage devices, such as magnetic disks, to tertiary or mass storage devices, such as automated tape libraries. It provides a service analogous to demand paging in virtual memory systems.

Fixing file descriptor leaks
… implement and test a tool for eliminating file descriptor (FD) leaks in programs at run-time. Our tool monitors FD allocation and use. When the allocation of a new FD would fail because a process's entire pool of FDs is already in use, our tool "recycles" (forcibly closes) an FD. The FD to …

Comparison of file sanitization techniques in USB based on average file entropy values
… deleted is invisible but not gone. This is where file sanitization plays it role. File sanitization is the process of deleting the memory of the content and over write it with a different characters. In this research, the methods chosen to sanitize file are Write Zero, Write Zero Randomly and …

File Tracking For Mobile Devices
Since 2010, the smart device has become an integral part of people’s daily lives. The popularity of smart devices has increased dramatically. However, as the number of devices owned by an individual user increases, so does the risk of data leakage and loss. This problem has started to draw …

Decentralized infrastructure for file storage
… a peer-to-peer network to store users' files? The purpose of this research is to combine ideas from existing peer-to-peer file sharing systems, blockchain technology and Proofs-of-Storage to create an incentivized decentralized storage network, where every participant can earn a reward …

SloanSpace- DSpace file transfer component
… both developed at MIT. In particular, a file transfer component was created that enables SloanSpace users to search and retrieve DSpace documents while in SloanSpace, and submit SloanSpace documents into DSpace. DSpace's web services provided the means for interaction between the systems. …

File system unification using LatticeFS
… system designed to merge multiple source file systems into a single working file system. atticeFS can be used to merge multiple software package directories, work with multiple file systems as if they are one, and share a single storage medium among multiple machines. On a high level, …

MICROLAN file transfer program for microprocessors
… system. To provide a readily available, low-cost file transfer system, the authors developed an assembly language program named MICROLAN, which is written to work with three of the main microcomputer operating systems (CP/M-80, CP/M-86, and IIS. DOS) and to take advantage of RS232 technology. …

Raptorq-Based Multihop File Broadcast Protocol
… error correction. This protocol can deliver a file reliably to a large number of nodes in a wireless multihop network even if the links have high loss rates. We use mixed integer programming with power balance constraints to construct broadcast trees that are suitable for implementing the …

File Sharing e problematiche giuridiche nell'U.E.
In informatica e telecomunicazioni il file sharing è la condivisione di file all'interno di una rete di calcolatori comuni e come fenomeno di massa, è strettamente legato alla diffusione di Internet e della banda larga. Il file sharing è cresciuto in popolarità e si è diffuso rapidamente …
