Extract Method
Extracts the compressed file from the archive.
procedure Extract();
Remarks
Invoking Extract decompresses the archive specified by ArchiveFile. The compressed file will be extracted, and written to disk.
If FileDecompressedName is set to a nonempty string the file will be written there. Otherwise the component will automatically set FileDecompressedName to an appropriate value:
If FileDecompressedName is empty and ArchiveFile ends in '.Z', this filename, less the '.Z' extension will be used. Otherwise the extension '.uncompressed' will be appended to the file name.
