<p>The decoder has the following limitations, as written by Igor Pavlov in the LZMA SDK:</p>
|

-It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.<br />

|

-It does not support PPMd and BZip2 methods.<br />

<li>It reads only "FileName", "Size", "LastWriteTime" and "CRC" information for each file in archive.</li>
|

-It converts original UTF-16 Unicode file names to UTF-8 Unicode file names.<br />

You can create .7z archive with 7z.exe, 7za.exe or 7zr.exe:<br /><br />
|
</ul>
|
||||||
7z.exe a archive.7z *.htm -r -mx -m0fb=255<br /><br />

<p>To expand on his comments about RAM consumption: When extracting a file, at least enough memory will always be allocated to hold the entire file, regardless of the block size. For example, extracting a 1 GB file using <tt>Extract7ZipArchive</tt> requires at least 1 GB of RAM. Consider using a different solution for extracting large files, such as embedding 7-Zip itself, which does not use as much RAM, into your installation.</p>
|
||||||
If you have big number of files in archive, and you need fast extracting, you can use partly-solid archives:<br /><br />
|
<p>Additionally he wrote:</p>
|
||||||
7za.exe a archive.7z *.htm -ms=512K -r -mx -m0fb=255 -m0d=512K<br /><br />
|
<ul>
|
||||||
In that example 7-Zip will use 512KB solid blocks. So it needs to decompress only 512KB for extracting one file from such archive.</p></remarks>
