The ZCompress class implements an LZC compressor and decompressor. It is compatible with the UNIX compress utility.
The LZC file format is used only to archive a single file. Accordingly, the operation of the class is simpler than that of the other classs.
To compress with the class, 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()
