<p>The corresponding menus can be installed with <a href="../urls/index.html#">url services</a>.</p>
<h4 id="features">Features</h4>
<p>The following mentioned subfolders locate in the configuration folder.</p>
<ul>
<li>
<p>The following html5 applications are allowed to read local files referred by &quot;https://local/sdcard/...&quot; where the &quot;/sdcard/..&quot; part is the full path of the file. The below applications <span style="color:red">can auto choose any files as file objects</span>.</p>
<ul>
<li>Locating in a subfolder whose name begins with &quot;app&quot; (such as &quot;appPDF&quot;)</li>
<li>&quot;https://local/...&quot; applications (only possible with the option &quot;<a href="../offlinecache/index.html#">use offline resources</a>&quot; and installed under the folder &quot;sitecache/local/&quot;)</li>
</ul>
</li>
<li>
<p><span style="color:red">All files under the subfolder &quot;app&quot; can be automatically choosed as file objects by any web page</span>.</p>
</li>
<li>
<p><span style="color:red">Local files (including binary files) can be processed by appending &quot;?app=[html5 app url]&quot; to the file urls.</span> Ex. &quot;file:///..../xx.md?app=https://...../app.html&quot; loads &quot;app.html&quot; first, then &quot;app.html&quot; processes the local file.</p>
</li>
</ul>
<p>With the first approach, the html5 application is installed locally and can read any file allowed by the OS; while in the second approach, the html5 application can be either local or remote, and only files under the subfolder &quot;app&quot; can be accessed; The third approach allows easy access of other external resources (ex. local media).</p>
<h4 id="open-local-files-with-html5-apps">Open local files with html5 apps</h4>
<p>Click to configure <a href="../filecap/index.html#">default.filecap</a> to open local files, and to open remote files with the option &quot;custom file handling&quot;:<br>
<a target="_self" href="i:0gdefault.filecap:../../zh/searchurl/txt/filecap.cfg">use pdf.js,djvu.js,epub.js, huge markdown viewer for local files</a></p>
<p>url examples are as follows:</p>
<ul>
<li>file:///data/user/0/info.torapp.uweb/files/app/pdfviewer.html?file=[path].pdf#page=[xxx]</li>
<li>file:///data/user/0/info.torapp.uweb/files/app/djvu.html?url=...xx.pdf#page=[xxx]</li>
<li>file:///data/user/0/info.torapp.uweb/files/app/txtview.html?url=[url]#page=[xxx]</li>
<li>file:///data/user/0/info.torapp.uweb/files/app/txtview.html?url=[url]#offset=[xxxx]&amp;[length]</li>
<li>file:///data/user/0/info.torapp.uweb/files/app/markdeep.html?url=[url]#page=[xxx]</li>
<li>file:///data/user/0/info.torapp.uweb/files/app/markdeep.html?url=[url]#offset=[xxxx]&amp;[length]</li>
</ul>
<p>Ex. &quot;#offset=10000&amp;500&quot; will retrieve 500 bytes from offset 10000. Click the right arrow button to next page in all above file viewers.</p>
<h4 id="configure-html5-app-subfolder-app-optional">Configure html5 app subfolder &quot;app&quot; (optional)</h4>
<p>By default, the subfolder &quot;app&quot; is created by clicking to install any of above html5 applications.</p>
<p>To make file management easier, users can symbolic link the subfolder &quot;app&quot; to any other locations as long as it is readable.</p>
<p>One way to configure &quot;app&quot; subfolder is as follows:</p>
<ul>
<li><a href="i:15d:text/plain:toybox mkdir -p /sdcard/Download/app;toybox ln -s /sdcard/Download/app 2>&1:">Click to copy the command to the address bar</a></li>
<li>Press the home screen button of uweb browser bottom toolbar, so the home screen appears.</li>
<li>If you want &quot;app&quot; to be locations other than &quot;/sdcard/Download/app&quot;, modify as you like.</li>
<li>Press &quot;enter&quot; on the address bar to execute the command.</li>
</ul>
<h4 id="mdict-dictionary-lookup-search-engines">mdict dictionary lookup search engines:</h4>
<p>Note: the following two mdict.html files are different.<br>
i:5ifile:///....../xxx.mdx,xxx.mdd?app=https://cdn.jsdelivr.net/gh/torappinfo/uweb/en/searchurl/mdict/mdict.html#word=%s</p>
<p>in which &quot;/.../xxx.mdx,xxx.mdd&quot; is the full path for the mdict dictionary files.</p>
<p>i:5ihttps://uwebzh.netlify.app/zh/searchurl/txt/mdict.html?file=mdict/xxx.mdx,mdict/xxx.mdd#word=%s</p>
<p>In the above mdict search engine string, the dictionary files (mdx, mdd) must locate in the &quot;app&quot; subfolder under the configuration folder. In above example, the files &quot;xxx.mdx&quot; and &quot;xxx.mdd&quot; locate in the folder &quot;.../app/mdict&quot;.</p>
<p>To make life easier, users can <a href="../acmd/index.html#">link the &quot;app&quot; subfolder</a> to any public accessible folder.</p>
<p>Use the mdx scanning <a href="../bookmark/index.html#">bookmark</a> to add mdict engines automatically, then cold start uweb browser to take effect.</p>
