### 34.3 File Archiving Utilities

— Function File: bunzip2 (bzfile)
— Function File: bunzip2 (bzfile, dir)

> Unpack the bzip2 archive bzfile to the directory dir. If dir is not specified, it defaults to the current directory.

> See also: bzip2, unpack, gunzip, unzip, untar.

— Function File: entries = gzip (files)
— Function File: entries = gzip (files, outdir)

> Compress the list of files and/or directories specified in files. Each file is compressed separately and a new file with a '.gz' extension is created. The original files are not modified. Existing compressed files are silently overwritten. If outdir is defined the compressed files are placed in this directory.

> See also: gunzip, bzip2, zip, tar.

— Function File: gunzip (gzfile, dir)

> Unpack the gzip archive gzfile to the directory dir. If dir is not specified, it defaults to the current directory. If gzfile is a directory, all gzfiles in the directory will be recursively gunzipped.

> See also: gzip, unpack, bunzip2, unzip, untar.

— Function File: entries = tar (tarfile, files)
— Function File: entries = tar (tarfile, files, root)

> Pack files files into the TAR archive tarfile. The list of files must be a string or a cell array of strings.

> The optional argument root changes the relative path of files from the current directory.

> If an output argument is requested the entries in the archive are returned in a cell array.

> See also: untar, bzip2, gzip, zip.

— Function File: untar (tarfile)
— Function File: untar (tarfile, dir)

> Unpack the TAR archive tarfile to the directory dir. If dir is not specified, it defaults to the current directory.

> See also: tar, unpack, bunzip2, gunzip, unzip.

— Function File: entries = zip (zipfile, files)
— Function File: entries = zip (zipfile, files, rootdir)

> Compress the list of files and/or directories specified in files into the archive zipfile in the same directory. If rootdir is defined the files are located relative to rootdir rather than the current directory.

> See also: unzip, bzip2, gzip, tar.

— Function File: unzip (zipfile)
— Function File: unzip (zipfile, dir)

> Unpack the ZIP archive zipfile to the directory dir. If dir is not specified, it defaults to the current directory.

> See also: zip, unpack, bunzip2, gunzip, untar.

— Function File: files = unpack (file)
— Function File: files = unpack (file, dir)
— Function File: files = unpack (file, dir, filetype)

> Unpack the archive file based on its extension to the directory dir. If file is a list of strings, then each file is unpacked individually. If dir is not specified, it defaults to the current directory. If a directory is in the file list, then the filetype must also be specified.

> The optional return value is a list of files unpacked.

> See also: bzip2, gzip, zip, tar.

— Function File: entries = bzip2 (files)
— Function File: entries = bzip2 (files, outdir)

> Compress the list of files specified in files. Each file is compressed separately and a new file with a '.bz2' extension is created. The original files are not modified. Existing compressed files are silently overwritten. If outdir is defined the compressed files are placed in this directory.

> See also: bunzip2, gzip, zip, tar.
