    <p>I need to enumerate all the file in a folder and then navigate to the subfolder and do the same (recursion? sure).</p> <p>Ideally the algorithm should work in the same way on linux &amp; macos</p> <p>DISCLAIMER: I have asked a similar question on POSIX: I'm now aware of VFS but I'm puzzled to use VFS for enumerate dir. Any suggestion ? Should I open a dir as file ? The only way is to use a library cross platform like qt ?</p> <p>UPDATE: so no <strong>VFS</strong> way to work on directory? "*<em>V</em>*irtual *<em>F</em>*ile *<em>S</em>*ystem provides a single API for accessing various different file systems" but no way to enumerate directory. </p> <p>The "readdir" etc solution will do the trick on any type of *NIX ? And on windows nothing better than the huge MingW lib? or partial impletion working on only some win like: <a href="https://github.com/xbmc/xbmc/blob/master/tools/TexturePacker/Win32/dirent.c" rel="nofollow">https://github.com/xbmc/xbmc/blob/master/tools/TexturePacker/Win32/dirent.c</a></p> <p>The BOOST seem to be a really cool solution but it's complex and academic. thnks in any case</p> <p><strong>LAST UPDATE</strong>:<br> I have found some more doc and now everything is a lot more clear. <strong>This question is a duplicate!</strong> opendir() and readdir() are the solution to enumerate and browse directory on linux. As shown on my example is quite easy to map them on windows (but the incoerent windowz fs make everything strange) and ntfw() is even more useful. </p> <p><strong>VFS</strong> (the virtual file switch) is a kernel feature that resolves this problem by creating an abstraction layer for file-system operations. closed doc here: <a href="http://my.safaribooksonline.com/book/programming/linux/9781593272203/file-systems/the_virtual_file_system_open_parenthesis" rel="nofollow">linux programming interface</a></p> <p>thnks!</p>

    3. COI 'm intersted in a C simple and easy solution that I will wrap in a cpp container. To better undestand I have created a quick github project with a simple windows test in a single c file here: https://github.com/maborg/scandir feel free to fork an modify. just for fun off course (the pertinent c file is here: https://github.com/maborg/scandir/blob/master/scandir/readdir.c )

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
