Scan Method

Scans the compressed archive.

procedure Scan();

Remarks

This method will scan the bzip archive specified by ArchiveFile. The archive will be read, and the header will be checked.

Unlike in the Zip, Tar, and Jar components, it is never necessary to invoke this method, and it will not be automatically invoked by Extract. Suggested uses for this method would be to check that the file is a bzip file.
