Split File Shell Extension

Company / developer:
  BERGER Laurent

Split Files Shell Extension is a free, helpful Windows 95/98 and Windows NT utility designed for anyone who frequently works with oversized files. It works with the Windows 95 Explorer right-click menu to offer a quick and easy way to split large files into smaller pieces, directly onto floppies or to any other drive system (local or remote) on your computer (this includes CD-RW and tapes drives).

Visual SourceSafe

Company / developer:
  Microsoft Corporation

Visual SourceSafe

Microsoft Visual SourceSafe (VSS) is a source control software package oriented towards small software development projects. Like most source control systems, SourceSafe creates a virtual library of computer files. Users can read any of the files in the library at any time, but in order to change them, they must first "check out" the file. They are then allowed to modify the file and finally check it back in. The changes are made available to the other users only after the file has been checked in. Thus, a file cannot be edited by multiple users simultaneously. While most commonly used for source code, SourceSafe can actually handle any type of file in its database, but prior versions have been shown to be unstable when confronted with large amounts of non-textual data (images, binary executables, etc).

Dragon UnPACKer

Company / developer:
  Alexandre Devilliers

Dragon UnPACKer is a game archive (Quake PAK, etc..) unpacking tool. It is plugin based making easier to add new archive file formats.

Dragon UnPACKer has a convert ability and raw search function for known material (audio, video and pictures).

Dragon UnPACKer gives you the possibility to see into the big files in games like Quake, Unreal ...etc and extract files to anywhere you want easily.

Dragon UnPACKer can also convert some formats to more common formats.

Unix

Unix

Unix operating systems are widely used in both servers and workstations. The Unix environment and the client-server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.

Both Unix and the C programming language were developed by AT&T and distributed to government and academic institutions, causing both to be ported to a wider variety of machine families than any other operating system. As a result, Unix became synonymous with "open systems".

Unix was designed to be portable, multi-tasking and multi-user in a time-sharing configuration. Unix systems are characterized by various concepts: the use of plain text for storing data; a hierarchical file system; treating devices and certain types of inter-process communication (IPC) as files; and the use of a large number of software tools, small programs that can be strung together through a command line interpreter using pipes, as opposed to using a single monolithic program that includes all of the same functionality. These concepts are known as the Unix philosophy.

Under Unix, the "operating system" consists of many of these utilities along with the master control program, the kernel. The kernel provides services to start and stop programs, handle the file system and other common "low level" tasks that most programs share, and, perhaps most importantly, schedules access to hardware to avoid conflicts if two programs try to access the same resource or device simultaneously. To mediate such access, the kernel was given special rights on the system, leading to the division between user-space and kernel-space.

The microkernel concept was introduced in an effort to reverse the trend towards larger kernels and return to a system in which most tasks were completed by smaller utilities. In an era when a "normal" computer consisted of a hard disk for storage and a data terminal for input and output (I/O), the Unix file model worked quite well as most I/O was "linear". However, modern systems include networking and other new devices. As graphical user interfaces developed, the file model proved inadequate to the task of handling asynchronous events such as those generated by a mouse, and in the 1980s non-blocking I/O and the set of inter-process communication mechanisms was augmented (sockets, shared memory, message queues, semaphores), and functionalities such as network protocols were moved out of the kernel.

The Unarchiver

Company / developer:
  Dag Ågren/WAHa.06x36

The Unarchiver

The Unarchiver is a much more capable replacement for "BOMArchiveHelper.app", the built-in archive unpacker program in Mac OS X. The Unarchiver is designed to handle many more formats than BOMArchiveHelper, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip, LhA, StuffIt and many other more or less obscure formats
