- <h3>Installing Pocket UnZip</h3>
- <p>Place <strong>PUNZIP.EXE</strong> and <strong>PUNZIP.HTP </strong>(optional
- help file) into your <strong>Windows</strong> directory on your
- H/PC.</p>
- <p>From your H/PC's <strong>Start Menu</strong>, choose <strong>Run...</strong>,
- enter "<strong>punzip</strong>", and tap <strong>OK</strong>.</p>
- <p>The first time you run Pocket UnZip, it will register itself
- as the application for handling Zip files. From then on, you can
- just double-tap on Zip files in Explorer or from your Desktop to
- open them in Pocket UnZip.</p>
- <hr>
- <h3>Opening a Zip File</h3>
- <p>There are several ways to open a Zip file.</p>
- <ul>
- <li>Double-tap on a Zip file in Windows CE Explorer or from
- your Windows CE desktop. </li>
- <li>From within Pocket UnZip, choose the <strong>Open...</strong>
- command from the <strong>File</strong> menu. You may also
- tap the <strong>Open</strong> toolbar button or press <strong>Ctrl+O</strong>.
- </li>
- <li>Pocket UnZip keeps track of the four most recently opened
- Zip files. You may quickly open one of these recent files
- by selecting the Zip file directly from Pocket UnZip's <strong>File</strong>
- menu.</li>
- </ul>
- <hr>
- <h3>Zip File Listing</h3>
- <p>Pocket UnZip's main view displays a list of files,
- directories, and volume labels that are stored within the
- currently loaded Zip file. This list can be displayed in two
- modes, normal and expanded. The normal mode is sufficient for
- most users. It contains the following information for every item
- in the Zip file:</p>
- <ul>
- <li><strong>Name</strong>: Name and path of the compressed
- file, directory, or volume label.</li>
- <li><strong>Size</strong>: Size, in bytes, that the item
- requires when uncompressed.</li>
- <li><strong>Type</strong>: Type of item.</li>
- <li><strong>Modified</strong>: Date and time that the item
- was last modified.</li>
- </ul>
- <p>Expanded mode contains all the above information, plus the
- following additional information:</p>
- <ul>
- <li><strong>Attributes</strong>: Attributes of the item.
- <ul>
- <li><font face="Courier New"><strong>V</strong></font>:
- Volume label</li>
- <li><font face="Courier New"><strong>D</strong></font>:
- Directory</li>
- <li><font face="Courier New"><strong>R</strong></font>:
- Read-only file</li>
- <li><font face="Courier New"><strong>A</strong></font>:
- Archive file</li>
- <li><font face="Courier New"><strong>H</strong></font>:
- Hidden file</li>
- <li><font face="Courier New"><strong>S</strong></font>:
- System file</li>
- <li><font face="Courier New"><strong>E</strong></font>:
- Encrypted (this file will require a password)</li>
- <li><font face="Courier New"><strong>C</strong></font>:
- Comment (this item has a comment)</li>
- </ul>
- </li>
- <li><strong>Compressed</strong>: Compressed size, in bytes,
- of the item.</li>
- <li><strong>Ratio</strong>: Compression ratio of the item.</li>
- <li><strong>Method</strong>: Compression method used to
- compress the item.</li>
- <li><strong>CRC</strong>: 32 bit Cyclic Redundancy Check
- signature of the item.</li>
- <li><strong>Comment</strong>: Optional comment string that
- was associated with the item when compressed.</li>
- </ul>
- <p>You may toggle between the normal view and the expanded view
- by selecting the <strong>Extended View</strong> option from the <strong>View</strong>
- menu, or by tapping the associated toolbar button.</p>
- <hr>
- <h3>Properties Dialog</h3>
- <p>The properties dialog is useful for viewing detailed
- information for one or more files. It is invoked by selecting one
- or more files in the file list and then choosing <strong>Properties</strong>
- from the <strong>File</strong> menu. For convenience, you can
- also tap the toolbar button or press <strong>Alt+Enter</strong>.</p>
- <p>If one file is selected, the properties dialog will show you
- detailed information about that one file and its comment.</p>
- <p>If multiple files are selected, the dialog will show you
- combined results for all the files selected. Cumulative results
- will be given for the file count, byte counts, and compression
- ratio. Merged results will be given for the compression method,
- date, CRC, attributes, and comment. For the date, all values that
- are common between the selected files (such as year), will be
- shown with their common value. All values that differ between the
- selected files will be shown as question marks. For attributes, a
- black check means that all selected files have that particular
- attribute, a gray check mark means that some of the selected
- files have that attribute, and no check mark means that none of
- the selected files have that attribute.</p>
- <p>By using the properties dialog with multiple files, you can
- determine things like... What is the total number of files or
- bytes in the Zip file? What is the total compression ratio for
- all selected files. Are all the selected files from the same
- year? Same month? How many files have comments?</p>
- <hr>
- <h3>File Comments</h3>
- <p>Zip files provide two levels of commenting. At compression
- time, users can add per-file comments, as well as one main
- comment for the entire Zip file. The per-file comments are
- usually used to give a short description of each file. The main
- comment is usually used for credits, copyright information,
- installation instructions, version numbers, etc. Pocket UnZip
- can display both types of comments. </p>
- <p>Per-file comments can be viewed in Comments column of the main
- file list while in expanded mode (see the <strong>Zip File Listing</strong>
- section) and also in the properties dialog (see the <strong>Properties
- Dialog</strong> section).</p>
- <p>The main Zip file comment can be viewed by selecting <strong>Zip
- File Comment</strong> from the <strong>View</strong> menu or by
- pressing the associated toolbar button. This option will be
- disabled if the Zip file does not contain a main comment.</p>
- <hr>
- <h3>Extracting Files</h3>
- <p>Once you have opened a Zip file into Pocket UnZip, you should
- see a list of the Zip file's contents. Select one or more files
- from the file list and then choose <strong>Extract Selected Files</strong>
- (<strong>Ctrl+E</strong>) or <strong>Extract All Files</strong> (<strong>Ctrl+A</strong>,
- <strong>Ctrl+E</strong>) from the <strong>Action</strong> menu. You may
- also use the noted shortcut keys or the associated toolbar
- buttons.</p>
- <p>An extract options dialog will appear showing you some
- statistics about the files you are about to extract and prompting
- you for some information. There are three options available to
- you.</p>
- <p>The <strong>Restore file paths</strong> option allows you to
- control whether the directory structure of the files you have
- selected to extract will be preserved. When this option is
- checked, any directory paths associated with the compressed files
- will be created, and the file will be extracted to the newly
- created directory. If this option is not checked, all files will
- be extracted to a single directory, regardless of any path
- information associated with the compressed files.</p>
- <p>The <strong>Overwrite Options</strong> allow you to tell
- Pocket UnZip what to do if a file already exists on your file
- system with the same name of a file that is about to be
- extracted. The choices are:</p>
- <ul>
- <li><strong>Prompt to overwrite</strong>: Causes a dialog to
- appear for every situation that involves possibly
- overwriting a file. This allows you to decide what files
- get overwritten on a file-by-file basis. </li>
- <li><strong>Overwrite if newer</strong>: Causes Pocket UnZip
- to automatically overwrite any files that have a date and
- time that is earlier then the date and time of the file
- being extracted. This option can be useful for updating
- files. </li>
- <li><strong>Always overwrite</strong>: Causes Pocket UnZip to
- always automatically overwrite any files without
- prompting or warning. Use with caution. </li>
- <li><strong>Never overwrite</strong>: Causes Pocket UnZip to
- automatically skip all files that already exist on the
- file system.</li>
- </ul>
- <p>The <strong>Extract To</strong> field specifies the root
- directory that should be used to extract files to. If you checked
- the <strong>Restore file paths</strong> option, then any
- directories associated with the files being extracted will be
- created under the directory specified in this field. The
- directory you enter must already exist. To create directories and
- browse for directories, use the <strong>Browse...</strong>
- button.</p>
- <p>Once you have chosen the options you wish to use, press the <strong>Extract</strong>
- button. A progress dialog will appear and the extraction will
- begin. At any time during the extraction, you may tap the <strong>Abort</strong>
- button to abort the extraction operation.</p>
- <p><strong>Note: Aborting the
- extraction operation while processing a file will likely cause a
- partial file to get extracted and saved.</strong></p>
- <p>During the extraction, you may get interrupted for one of
- three reasons. First, if an error occurs, you will be notified
- with a message box. Second, if you have chosen the <strong>Prompt
- to overwrite</strong> option and you are trying to extract a file
- that already exists, you will be prompted on how to handle the
- situation. Third, if a file being extracted is encrypted, then
- you will be prompted for that file's password (see the <strong>Encrypted
- Files</strong> section).</p>
- <p>Once the extraction is complete, the <strong>Abort</strong>
- button will change to a <strong>Close</strong> button and any
- errors or warnings will be displayed. Tap the <strong>Close</strong>
- button to return to Pocket UnZip's main screen.</p>
- <hr>
- <h3>Testing Files</h3>
- <p>Testing files is essentially the same as extracting files,
- except for that the actual extracted data is never written to
- your file system. Testing files is useful when you wish to verify
- the integrity of a Zip file without actually extracting the files
- within it.</p>
- <p>Once you have opened a Zip file into Pocket UnZip, you should
- see a list of the Zip file's contents. Select one or more files
- from the file list and then choose <strong>Test Selected Files</strong>
- (<strong>Ctrl+T</strong>) or <strong>Test All Files</strong> (<strong>Ctrl+A</strong>,
- <strong>Ctrl+T</strong>) from the <strong>Action</strong> menu. You may
- also use the noted shortcut keys or the associated toolbar
- buttons.</p>
- <p>A progress dialog will appear and the testing will begin. At
- any time during the testing, you may tap the <strong>Abort</strong>
- button to abort the testing operation.</p>
- <p>During the testing, you may get interrupted for one of two
- reasons. First, if an error occurs, you will be notified with a
- message box. Second, if a file being tested is encrypted, then
- you will be prompted for that file's password (see the <strong>Encrypted
- Files</strong> section).</p>
- <p>Once the testing is complete, the <strong>Abort</strong>
- button will change to a <strong>Close</strong> button and any
- errors or warnings will be displayed. Tap the <strong>Close</strong>
- button to return to Pocket UnZip's main screen.</p>
- <hr>
- <h3>Viewing Files</h3>
- <p>Pocket UnZip provides the ability to view, or even execute,
- files directly from a Zip file. This feature is a major
- convenience over having to extract and then manually open each
- file you wish to view. Internally, this is what Pocket UnZip is
- doing for you, but it takes care of all the work of extracting
- the file to a temporary directory, launching the associated
- viewer for that file type, and cleaning up when done.</p>
- <p>To view a file, simply select a single file from Pocket
- UnZip's main file list and press <strong>Enter</strong>. You may also
- choose <strong>View Selected File</strong> from the <strong>Action</strong>
- menu, press the associated toolbar button, or just double-tap on
- the file you wish to view.</p>
- <p>The file will be extracted to a directory called<strong>
- Temporary Pocket UnZip Files</strong> in the root of your file
- system. If the file you wish to view is encrypted, you will be
- prompted for a password. If the file has an associated viewer
- application installed (such as Pocket Word for .PWD files), then
- that viewer will automatically be launched with the newly
- extracted file as its command line. If there is no associated
- viewer application, then you will be prompted for the application
- you wish to use to view the file.</p>
- <p>Pocket UnZip also provides minimal support for allowing you to
- use the view file action to run executable programs directly from
- the Zip file. If the file you choose to view is an executable
- (file extension is EXE), then the file will be executed after it
- is extracted. Pocket UnZip will only extract the file you select
- and none of its dependent files (like DLLs). If the executable
- you extract depends on other files in the Zip file, it will most
- likely fail to execute.</p>
- <p>When Pocket UnZip exits, it will delete the <strong>Temporary
- Pocket UnZip Files</strong> directory and all the files in it. If
- you are running more than one instance of Pocket UnZip, then only
- the last instance of Pocket UnZip that you exit will perform this
- delete. Most applications, such as Pocket Word, lock files when
- viewing them. Any files being viewed by such an application when
- you exit Pocket UnZip will not be deleted.</p>
- <hr>
- <h3>Encrypted Files</h3>
- <p>If an encrypted file is encountered during an extract, test,
- or view operation, you will be prompted for a password. You can
- choose to skip the file, skip all encrypted files, or enter a
- password. You will be given three attempts at entering the
- correct password before the file will be skipped automatically.
- Once you have entered the correct password for a given file, that
- password will be remembered and automatically used for all other
- encrypted files that are encountered during that single extract,
- test, or view operation. If another encrypted file is found that
- uses a different password than the remembered password, then you
- will be prompted again for a new password.</p>
- <p>This technique provides support for multi-password Zip files,
- while still providing users with single password Zip files the
- convenience of only having to enter their password once during
- the operation for all encrypted files. For security reasons,
- passwords are not remembered after the operation completes.</p>
