KDE supports networktransparency via KIO-slaves. <span class="application">KDiff3</span> uses this
for reading input files and for scanning directories.
This means that you can specify files and directories on local and
remote resources via URLs.
</p><p>
Example:
</p><p>
<pre class="screen">
<span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="command"><span><strong class="command">kdiff3</strong></span></span> test.cpp ftp://ftp.faraway.org/test.cpp
<span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="command"><span><strong class="command">kdiff3</strong></span></span> tar:/home/hacker/archive.tar.gz/dir ./dir
</pre>
</p><p>The first line compares a local file with a file on an FTP-server. The second line
compares a directory within an compressed archive with a local directory.
</p><p>
Other KIO-slaves that are interesting are:
</p><div class="itemizedlist"><ul type="disc"><li><p>Files from the WWW (http:),</p></li><li><p>Files from the FTP (ftp:),</p></li><li><p>Encrypted file transfer (fish:, sftp:),</p></li><li><p>Windows-ressources (smb:),</p></li><li><p>Local files (file:),</p></li></ul></div><p>
Other things that are possible, but probably less useful are:
</p><div class="itemizedlist"><ul type="disc"><li><p>Man-pages (man:),</p></li><li><p>Info-pages (info:),</p></li></ul></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2569517"></a>How To Write URLs</h3></div></div></div><p>
An URL has a different syntax compared with paths for local files and directories.
Some things should be considered:
</p><div class="itemizedlist"><ul type="disc"><li><p>
A path can be relative and can contain "." or "..". This is not possible for URLs
which are always absolute.
</p></li><li><p>
Special characters must be written with "escaping". ("#"->"%23", space->"%20", etc.)
E.g. A file with the name "/#foo#" would have the URL "file:/%23foo%23".
</p></li><li><p>
When URLs don't work as expected, try to open them in Konqueror first.
</p></li></ul></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2569553"></a>Capabilities of KIO-Slaves</h3></div></div></div><p>
Networktransparency has one drawback: Not all ressources have the same cababilities.
</p><p>
Sometimes this is due to the file system of the server, sometimes due to the protocol.
Here is a short list of restrictions:
</p><div class="itemizedlist"><ul type="disc"><li><p>
Sometimes there is no support for links.
</p></li><li><p>
Or there is no way to distinguish if a link points to a file or a directory; always
assuming a file. (ftp:, sftp:).
</p></li><li><p>
Can't always determine the filesize.
</p></li><li><p>
Limited support for permissions.
</p></li><li><p>
No possibility to modify permissions or modification time, so permissions or time
of a copy will differ from the original. (See the option "Trust the size".)
(To modify permissions or modification time is only possible for local files.)
