<div class="textblock"><p><a class="anchor" id="faq-non-QIODevice"></a>Q. Is there any way to use <a class="el" href="classQuaZipFile.html" title="A file inside ZIP archive. ">QuaZipFile</a> in Qt where you are supposed to use normal (non-zipped) file, but not through QIODevice API?</p>
<p>A. Usually not. For example, if you are passing file name to some database driver (like SQLite), Qt usually just passes this name down to the 3rd-party library, which is usually does not know anything about QIODevice and therefore there is no way to pass <a class="el" href="classQuaZipFile.html" title="A file inside ZIP archive. ">QuaZipFile</a> as a normal file. However, if we are talking about some place where you pass file name, and then internally use QFile to open it, then it is a good idea to make an overloaded method, which accepts a QIODevice pointer. Then you would be able to pass <a class="el" href="classQuaZipFile.html" title="A file inside ZIP archive. ">QuaZipFile</a> as well as many other nice things such as QBuffer or QProcess. Of course, that's only possible if you have control over the sources of the particular class.</p>
<p><a class="anchor" id="faq-zip64"></a>Q. Can QuaZIP handle files larger than 4GB? What about zip64 standard?</p>
<p>A. Starting with version 0.6, QuaZIP uses Minizip 1.1 with zip64 support which should handle large files perfectly. The zip64 support in Minizip looks like it's not 100% conforming to the standard, but 3rd party tools seem to have no problem with the resulting archives.</p>
<p><a class="anchor" id="faq-seekable"></a>Q. Can QuaZIP write archives to a sequential QIODevice like QTcpSocket?</p>
<p>A. Yes, it's possible since QuaZIP v0.7. It's only possible in mdCreate mode, no mdAppend support.</p>
<p><a class="anchor" id="faq-Minizip-update"></a>Q. Can I use another version of Minizip in QuaZIP, not the bundled one?</p>
<p>A. No, unfortunately not. To support reading/writing ZIP archives from/to QIODevice objects, some modifications were needed to Minizip. Now that there is a Minizip fork on GitHub, it is theoretically possible to backport these modifications into Minizip in a backward-compatible manner to ensure seamless integration with QuaZIP, but it hasn't been done yet, and there are no short-term plans, only a long-term goal. </p>
