• Create an archive in order to group and compress your files.
• Add files into an archive in order to save them.
• Add directories into an archive in order to save the files found in these directories.
• Split an archive for a distribution over several volumes (diskettes, CDs...).
• Merge an archive that is split into several sub-archives.
• Create a self-extracting archive.

1. Launch WDZIP: under the "Tools" pane, in the "Utilities" group, click on "WDZip".. The WDZip window is displayed:
   
2. Click the "New" button or select "File .. New archive...". A file picker is displayed.
3. Type the name of archive to create and click "Save". By default, the extension of created archive will be ".WDZ". To create an archive in ZIP, CAB or 7z format, the extension must be specified in the file name.

1. Open (if necessary) the archive into which the files must be added (click the "Open" button or select "File .. Open an archive").
2. Click the "Add" button or select "Action .. Add a file".
3. Select the files to add.
   Reminder: To select multiple files, hold down the Ctrl key while selecting files.
4. Choose the backup mode of tree structure for the files to archive. The backup modes of tree structure are as follows:
   • Conserve the hierarchy: the file(s) will be archived with their relative hierarchy (<Directories...> + <File>).
   • Include system and hidden files: archives system and hidden files.
   • Store the absolute path: the file(s) will be archived with their complete directory structure (<Disk> + <Directories...> + <File>)
   • Password protection: the file(s) will require the specified password for any manipulation (replacement, extraction, etc.).
5. Specify (if necessary) the requested compression level (0 for no compression, 9 for a maximum compression).
6. Validate.

• To add files into an archive, you also have the ability to perform a Drag and Drop from the explorer to WDZip. In this case, the added files are automatically archived with their tree structure.
• The percentage of file compression (size of compressed files compared to their initial size) is indicated beside the name of files.
• The files can only be added into a single-part archive. To perform this operation on a multi-part archive, simply group the sub-archives together to obtain a single-part archive.

1. Open (if necessary) the archive into which the files must be added (click the "Open" button or select "File .. Open an archive").
2. Click the "Add" button or select "Action .. Add a file".
3. Select the directory to add and click the "Open" button.
4. Choose the backup mode of the tree structure for the files found in the directory to archive. The backup modes of tree structure are as follows:
   • <Directories...> + <File> will be archived with their relative directory structure.
   • Include system and hidden files: archives system and hidden files in the directory.
   • Store the absolute path: the file(s) present in the directory will be archived with their complete hierarchy (<Disk> + <Directories...> + <File>)
   • Password protection: the file(s) in the directory will require the specified password for any manipulation (replacement, extraction, etc.).
5. Select the directories to add.
   Reminder: To select multiple folders, hold down the Ctrl key when selecting folders.
6. Validate.

• To add directories into an archive, you also have the ability to perform a Drag and Drop from the explorer to WDZip. In this case, the directories and their sub-folders are saved with their relative tree structure.
• The directories can only be added into a single-part archive. To perform this operation on a multi-part archive, simply group the sub-archives together to obtain a single-part archive.

• Merge the different parts,
• Extract the files.

1. Open (if necessary) the archive to split (click the "Open" button or select "File .. Open an archive").
2. Click the "Split" button or select "Action .. Split the archive".
3. The window for configuring the splitting of the archive is displayed.
4. Set the size of the sub-archives (the suggested size ranges from 360 KB to 64 MB).
   Note: If you select "Other", enter the archive size in kilobytes or megabytes, depending on the option chosen..
   Please note: The size of sub-archives cannot be less than 360KB.
5. If the original "WDZ" or "ZIP" file must be deleted after splitting the archive, check "Delete the source archive after the split operation".
6. Validate.

1. Open (if necessary) the first file of the multi-part archive (click the "Open" button or select "File .. Open an archive"). The extension of this archive is ".WDZ" or ".ZIP".
2. Select "Action .. Merge the archives".
3. The merged archive is now a single-part archive.

Create a self-extracting archive

• The archive exists.
• The archive is accessible in read/write.
• The archive is a single-part archive.

1. Open (if necessary) the archive that must be converted into self-extracting archive (click the "Open" button or select "File .. Open an archive").
2. Click the "Executable" button or select "Action .. Create a self-extracting archive".
3. Specify the directory where the files must be decompressed when the executable is run.
4. Specify whether a dialog box must be displayed during the extraction. This dialog box allows the user to choose the extraction path for example.
5. Validate. The self-extracting archive is created.
