The ZCompress component implements an LZC compressor and decompressor. It is compatible with the UNIX compress utility.
NOTE: What follows is a very short description of the component interfaces.
For more information, please consult the help files that come with the respective package.
Remarks
The LZC file format is used only to archive a single file. Accordingly, the operation of the
component is simpler than that of the other components.
To compress with the component, set ArchiveFile to the name of the LZC compressed file to be
created, and FileDecompressedName to the name of the file to be compressed. Finally, invoke
Compress. To extract the file, first set ArchiveFile. FileDecompressedName may then be
set; if not, it will automatically be set based on the ArchiveFile name. Finally, invoke the
Extract method.
Example (Creating an LZC File)
ZipControl.ArchiveFile = "c:\test.Z"
ZipControl.FileDecompressedName = "c:\test.txt"
ZipControl.Compress()
Example (Extracting from an LZC File)
ZipControl.ArchiveFile = "c:\test.Z"
ZipControl.FileDecompressedName = "c:\test.txt"
ZipControl.Extract()
