Back to: Cabarc User's Guide Currently, only three commands are supported; N (create new cabinet), L (list contents of an existing cabinet), and X (extract files from a cabinet).
These commands are described in the following pages.
Back to: Cabarc User's Guide Cabarc supports wildcards in the filename list, as shown in the example below: Creating Cabinets By default, all files are added to a single folder (compression history) in the cabinet.
It is possible to tell cabarc to begin a new folder, by inserting the plus (+) symbol as a file to be added, as shown below: The above command creates the cabinet "mycab.cab" with one folder containing "test.c" and "main.c", and a second folder containing "test.exe" and all files matching "*.obj".
Back to: Cabarc User's Guide Creating Cabinets By default, directory names are not preserved in the cabinet; only the filename component is stored.
List Cabinet Contents Extracting Cabinets The cabinet format provides a way to efficiently package multiple files.
The key features of the cabinet format are that multiple files may be stored in a single cabinet ("CAB file"); and that data compression is performed across file boundaries, significantly improving the compression ratio.
Depending upon the number of files to be compressed, and the expected access patterns (sequential or random access; whether most of the files will be requested at once or only a small portion), cabinets can be constructed in different ways.One key concept of the cabinet file is the is a collection of one or more files that are compressed together as a single entity.By compressing files in this way, the compression ratio is improved.The downside is that random access time suffers, since in order for any particular file in a folder to be decoded, all preceding files in the same folder must also be decoded.Back to top Cabarc is a utility that creates, extracts, and lists the contents of cabinet files (CABs), using a command line interface similar to that of popular archiving tools.Cabarc supports wildcards and recursive directory searches.
