PKZIP (also capitalized as PKZip) is a program, originally written for the DOS operating system , that gathers multiple files into a single compressed file that can be stored in less space and transmitted more quickly from one place to another.
PKZIP=PK Stands For Pakistan And ZIP Stands For Zone Improvement Plan.
PKZIP, which was later renamed PKWare, was invented by Philip K. Katz. PKZIP was a utility which compressed and decompressed data sent through telephone lines to other computers, saving quite a bit of time and money at the time.

WinZIP = Windows ZIP. It is derived from the program name 'PKZIP/UNZIP', created by the author Phil Katz from United States. [PKZIP is a program for creating zip files which ran under DOS].WinRAR = Windows Roshal ARchive. It is derived from the Russian engineer Eugene Roshal who created this RAR compression technology.
PkZIP is available for download directly from the developer on the PKWare website. It is also available for download through Softonic, Tucows, CNET and PC-Shareware.
To examine the file slack for each of the 9 files extracted from a PKZIP archive, you would first determine the size of each file and then compare it to the allocated space on the filesystem. You can use a hex editor or forensic analysis tool to open each file and check the slack space by analyzing the data beyond the actual file size up to the end of the allocated cluster. This slack space may contain residual data from previous files, which can be valuable for forensic investigation. Lastly, ensure to document your findings for each file's slack space analysis.
They are 'file compression' utilities. Basically, when windows saves a file, it's saved in fixed 'blocks' of data. ZIP programs 'strip out' the unused spaces in these blocks - reducing the amount of space the file occupies on the hard-drive. The files are 'unzipped' when they're in use, then compressed again back for storage.
An electronic file can be compressed so that it takes up less disk space for easier sharing by using one of several file compression softwares. WinZip, WinRAR, 7-Zip, PKZip, StuffIt are some of the most common softwares. The procedure for compressing a file depends on the software used but generally it is menu driven from the software and is done just by the click of the computer's mouse.
You cannot convert a .ZIP file to a .AUC file. A .ZIP file is an archive, and .AUC is audio. However, if there is an .AUC file located inside the .ZIP file, then you can extract it using software or even Windows internal .ZIP handling. First try double-clicking the .ZIP file to see if it opens. If it does, then deal with the files the same as you would files in a regular Windows folder. If not, then download PKZip, 7Zip, Rar!, or other archiver that handles .ZIP files. After installing an archiver, the likely action is to right-click the file you want to unzip and select unzip.
