Properties Methods Events Configuration Settings
The Gzip component implements a gzip compressor and decompressor, compliant to RFC 1952 and compatible with the UNIX gzip and gunzip utilities.
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.
The gzip file format 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 gzip 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 from the gzip file headers. Finally, invoke the Extract or Compress method.
.tar.gz files may be created or extracted in one step by using the Tar component. See the documentation for Tar for more details.
Example (Creating a Gzip File)
ZipControl.ArchiveFile = "c:\test.gz" ZipControl.FileDecompressedName = "c:\test.txt" ZipControl.Compress()
ZipControl.ArchiveFile = "c:\test.gz" ZipControl.FileDecompressedName = "c:\test.txt" ZipControl.Extract()
