<H1>-t (set Type of archive) switch</H1>
<P>Specifies the type of archive.</P>
<H4>Syntax</H4>
<PRE class="syntax">
-t{archive_type}[:s{Size}][:r][:e][:a]
</PRE>
<DL>
<DT>{archive_type}</DT>
<DD> Specifies the type of archive. It can be: *, #, 7z, xz, split, zip, gzip, bzip2, tar, ....
</DD>
<DT>*:r</DT>
<DD> Default mode. 7-Zip opens archive and subfile, if it's supported by format.
</DD>
<DT>*</DT>
<DD> Opens only one top level archive.
</DD>
<DT>*:s{Size}[b | k | m | g]</DT>
<DD>Sets upper limit for start of archive position.
Default scan size is 8 MBytes "*:s8m".
Example: "*:s0" means that it will open only file that has no any stub before archive.
</DD>
<DT>#</DT>
<DD> Opens file in Parser mode, and ignores full archives.
</DD>
<DT>#:a</DT>
<DD> Same as *, but it opens files with unknown extensions that contain archives in Parser Mode.
</DD>
<DT>#:e</DT>
<DD> Opens file in Parser mode and checks all byte positions as start of archive.
</DD>
</DL>
<P>If -t{archive_type} switch is not specified, 7-Zip uses extension of archive filename to
detect the type of archive. If you create new archive, -t{archive_type} switch is not
specified and there is no extension of archive, 7-Zip will create .7z archive.</P>
<P>If -t{archive_type} switch is not specified and archive name contains incorrect extension,
the program will show the warning.</P>
<P>It's possible to use the combined type (for example, mbr.vhd) for "Extract" and "List"
commands for some archives.</P>
<P>When you extract archive of some types that contains another
archive without compression (for example, MBR in VHD), 7-Zip can open both
levels in one step. If you want to open/extract just top
level archive, use <SPAN class="filename">-t*</SPAN> switch.</P>
<P>Note: xz, gzip and bzip2 formats support only one file per archive.
If you want to compress more than one file to these formats,
create a tar archive at first, and then compress it with your selected format.</P>
<H4>Example</H4>
<PRE class="example">
7z a -tzip archive.zip *.txt
</PRE>
<P>adds all <SPAN class="filename">*.txt</SPAN> files from current directory
to zip archive <SPAN class="filename">archive.zip</SPAN>.</P>
<PRE class="example">
7z t -t7z.split archive.7z.001
</PRE>
<P>tests all files in <SPAN class="filename">archive.7z.001</SPAN>. It also checks
that archive is multivolume .7z archive.</P>
<PRE class="example">
7z x -t# sfxarchive.exe
</PRE>
<P>extracts <SPAN class="filename">sfxarchive.exe </SPAN> in parser mode.</P>
<PRE class="example">
7z x -tiso archive.iso
</PRE>
<P>extracts files from <SPAN class="filename">archive.iso</SPAN> open as ISO archive.
<PRE class="example">
7z x -tudf archive.iso
</PRE>
<P>extracts files from <SPAN class="filename">archive.iso</SPAN> open as UDF archive.
