    <p>You should refactor your code so that the ftp commands are in functions and instead of copy/pasting those ftp commands everywhere, you have some flow like this:</p> <pre><code>String[] directories = ftpGetListing("ftp://myurl.com/mainfolder/"); String[] agents = Crawler.CrawlerDbUtils.getAllAgentIDs(); String[] combinedDirectories = getElementsInBothArray(directories, agents); String[] serverOnlyDirectories = getElementsOnlyInFirstArray(directories, agents); String[] agentOnlyDirectories = getElementsOnlyInFirstArray(agents, directories); // step 1: delete all server only directories ftpDeleteDirectories("ftp://myurl.com/mainfolder/", serverOnlyDirectories); // step 2: create all agent only directories ftpCreateDirectories("ftp://myurl.com/mainfolder/", agentOnlyDirectories); // step 3: depricate all files foreach(String dir in combinedDirectories) { String ftpDir = "ftp://myurl.com/mainfolder/" + dir + "/"; String[] serverFiles = ftpGetListing(ftpDir); String[] agentFiles = Crawler.CrawlerDbUtils.getAllPictures(dir); String[] serverOnlyFiles = getElementsOnlyInFirstArray(serverFiles, agentFiles); foreach(String file in serverOnlyFiles) { ftpDeleteFile(ftpDir + file); } } </code></pre> <p>Then you just have to implement really simple functions for <code>ftpGetListing</code>, <code>ftpDeleteDirectories</code>, <code>ftpCreateDirectories</code>, and <code>ftpDeleteFile</code>. Oh yeah and some simple array manipulation functions like: <code>getElementsInBothArrays</code> and <code>getElementsOnlyInFitstArray</code>.</p>

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.
