* Extract (CABINET.3)

*
* RETURNS
* Success: S_OK.

*
* NOTES
* The following members of the dest struct control the operation
* of Extract:
* FileSize [O] The size of all files extracted up to CurrentFile.
* Error [O] The error in case the extract operation fails.
* FileList [I] A linked list of filenames. Extract only extracts
* files from the cabinet that are in this list.
* FileCount [O] Contains the number of files in FileList on
* completion.
* Operation [I] See Operation.
* Destination [I] The destination directory.
* CurrentFile [O] The last file extracted.
* FilterList [I] A linked list of files that should not be extracted.
*
* Operation
* If Operation contains EXTRACT_FILLFILELIST, then FileList will be
* filled with all the files in the cabinet. If Operation contains
* EXTRACT_EXTRACTFILES, then only the files in the FileList will
* be extracted from the cabinet. EXTRACT_FILLFILELIST can be called
* by itself, but EXTRACT_EXTRACTFILES must have a valid FileList
* in order to succeed. If Operation contains both EXTRACT_FILLFILELIST
* and EXTRACT_EXTRACTFILES, then all the files in the cabinet
* will be extracted.
