WinDD - Data Decompressor for Windows    

Data Decompressor for Windows

Release 1.5

1. Introduction
WinDD is a software designed to run on Windows  PCs, in order to unpack files. At the present time, the supported packer formats are: BZip2, GZip, PowerPacker and Z-Compress.
This program is the graphic interface of the powerful Data Decompressor Engine implemented in VEGA and VEGA ZZ.

2. System requirements
- Pentium class CPU.
- Windows 32 or 64 bit operating system.
- libbz2.dll, zlib32.dll and locale.dll (included).

3. New in this release:

- Drag & drop function to specify the files to unpack.
- Minor bug fix.
- New look.

4. Usage:

WinDD is a true Win32 application powered by the VCL graphic interface:

The main window

In Files text box, you can type the name of files to decompress. If you want process more then one file, you must separate each file   with a semicolon (";"). Another way to insert the file names in the Files field is clicking on the Open button or selecting the File -> Open (Ctrl+O) menu. The standard Windows file requester is shown with the multiple selection function enabled.
To perform the unpacking operation, you must press the Unpack button or select File -> UnPack (Ctrl+U). While this operation, the status bar shows the name of file that is processed and if an error occurs, a message is reported in an alert window.
To close WinDD, you can click the specific button on the right corner of the window or select File -> Quit (Ctrl+Q).
With the Help menu, you can read this documentation (Contents) or the copyright message (About...)

5. Language localization
For the string language localization, was implemented in VEGA the Locale Technology of AmigaOS. This method allows to translate the language strings without recompile the source code. A simply translation of a template text file and a conversion with an included utility is needed.
Each language requires a translation file (called catalog) that has the name of the program that use it, and the .catalog extension (WinDD.catalog). Each file must be placed in a subdirectory with the name of the language (e.g. italiano, franšais, deutsch, etc) of the Catalogs folder, present  in the same directory where the program is located.
All programs having this technology can run without catalog files because the default language (e.g. english) is bult-in.
In order to translate all WinDD messages in your preferred language, you need the following components:

  • FlexCat catalog builder for Win32 (included).

  • Catalogs/ file.
    This is the text file used to generate the built-in language.

  • Catalogs/WinDD.ct file.
    This is the catalog template to edit in order to perform the language translation.

  • A text editor compatible with your operating system.

To create a new catalog file, you can follow these steps:

  • Open the WinDD.ct file with your text editor.

  • Change the first three lines:

    ## version $VER: XX.catalog XX.XX ($TODAY)
    ## language X
    ## codeset 0


    ## version $VER: WinDD.catalog 1.0 (compilation_date)
    ## language your_language
    ## codeset 0

    The compilation_date must be in DD.MM.YYYY format and your_language must be in lower case.

  • In each blank line, translate the string in the next line. Please use ANSI/ISO character set only.

  • Make sure that the special control characters are present in your translation also (e.g. %s, %.4f, \n, etc).

  • Save the WinDD.ct file.

  • Build the WinDD.catalog typing:
    flexxcat WinDD.ct CATALOG WinDD.catalog

  • Move WinDD.catalog in the appropriate directory (e.g. Catalog/YOUR_LANGUAGE/). Please note that the YOUR_LANGUAGE directory must be in lower-case, otherwise the Unix systems can't found the file.

  • The new catalog file is recognized automatically by the software.
