- *** What is WinZip Self-Extractor?
-
- WinZip Self-Extractor is a utility program that creates native
- Windows self-extracting ZIP files. These self-extracting ZIP
- files are ideal for electronic file distribution because they:
- (1) can contain multiple compressed files, ensuring that important
- files do not become separated from the rest of the package;
- (2) allow the receiver to use a familiar Windows interface to
- decompress files, without owning or knowing how to use a separate
- unzip utility; and (3) optionally run a "setup" or "installation"
- program, which may be included by the developer when the files are
- decompressed.
-
- WinZip Self-Extractor is an optional add-on to WinZip, an award
- winning utility to manipulate ZIP files.
-
- This portion of the documentation describes ZIP files and self-
- extracting ZIP files, discusses the benefits of self-extracting
- ZIP files, and summarizes WinZip Self-Extractor features.
-
- *** What is a ZIP file?
-
- The ZIP file format is an industry standard for compressing and
- grouping files. One ZIP file can contain multiple files. Files
- contained in a ZIP are usually compressed.
-
- Typical uses for ZIP files include:
-
- - Most files available in "file areas" on bulletin boards and
- electronic services like CompuServe and the Internet are
- distributed as ZIP files. Two benefits of using ZIP files for
- electronic file distribution are that only one file transfer
- operation ("download") is required to obtain all related files,
- and file transfer time is minimized because the files in a ZIP
- are compressed.
-
- - It is often useful to send a group of related files to an
- associate. Rather than distributing individual files it is
- often easier to distribute the files as a ZIP file to benefit
- from the file grouping and compression.
-
- ZIP files are created using a ZIP utility like WinZip(R) or the
- PKZIP(R) utility from PKWARE(R).
-
- *** What is a Self-Extracting ZIP File?
-
- A self-extracting ZIP file is an executable program file (.EXE
- file) that includes a ZIP file and software to extract or "unzip"
- the contents of the ZIP file. Users can run (execute) a
- self-extracting ZIP file just as they run any other program.
-
- When a self-extracting ZIP file created by WinZip Self-Extractor
- is run, a dialog box is displayed. This dialog box makes it easy
- for the user to change the "unzip to" folder and change other
- options before extracting or "unzipping" the files in the
- self-extracting ZIP file. Self-extracting ZIP files created by
- WinZip Self-Extractor are
-
- - 100% compatible with the PKZIP 2.04g file format, so they can be
- unzipped by standard unzip utilities like WinZip and PKUNZIP.
-
- - Only about 12k larger than a regular (not self-extracting) ZIP
- file.
-
- *** What are the advantages to Self-Extracting ZIP Files?
-
- Users can extract or "unzip" files from a self-extracting ZIP file
- without running a separate unzip utility or knowing how to use an
- unzip utility. Thus self-extracting ZIP files are particularly
- suited for distribution of software to beginning users who are not
- familiar with the concept of ZIP files.
-
- Self-extracting ZIP files created by WinZip Self-Extractor are
- native Windows programs so they are easy to use even for users
- with no MS-DOS experience.
-
- *** How Does it Work?
-
- There are two parts to WinZip Self-Extractor:
-
- 1) The WinZip Self-Extractor program creates self-extracting ZIP
- files.
-
- 2) When WinZip Self-Extractor creates a self-extracting ZIP file
- it includes part of itself in the self-extracting ZIP file.
-
- The part of WinZip Self-Extractor included in the self-extracting
- ZIP file is what makes it possible to unzip the files by simply
- running the self-extracting ZIP file.
-
- The person who creates the self-extracting ZIP file runs WinZip
- Self-Extractor once, specifying the name of the ZIP file and
- options, including the default "unzip to" folder and a program
- to be run automatically when the unzip operation completes.
- WinZip Self-Extractor stores this information in the self-
- extracting ZIP file so it is available when the self-extracting
- ZIP file is run. See the online help section titled "Creating
- Self-Extracting ZIP Files" for details on the procedure, and the
- file license.txt for information on licensing.
-
- *** Summary Of Features
-
- - Easy distribution of one or more compressed files.
-
- - Low overhead (as little as 12kb, depending on selected options)
-
- - Options to create 16-bit or 32-bit Windows self-extractors, or
- MS-DOS+Windows self-extractors (one EXE works on either MS-DOS
- or Windows).
-
- - An optional command is run when the unzip operation completes,
- making it easy to run a SETUP program included in a
- self-extracting ZIP file.
-
- - A Wizard to simplify the process of building self-extracting
- files.
-
- - Any folder information in the ZIP is automatically restored.
-
- - 100% compatible with the PKZIP 2.04g standard.
