Can I Delete any files in the Application Data\Apple Computer directory?

Question

I'm using and iPhone 4S and Windows XP.  (I know I'm WAY behind, and we're saving to buy an iMac soon.)  I have a plethora of files in this directory
C:\Documents and Settings\User\Application Data\Apple Computer\Logs\CrashReporter
Are there any files there I can delete.  Some of them on my iPhone 3G go back a couple years. 
And how about the files under here?
C:\Documents and Settings\User\Application Data\Apple Computer\MobilSync
Is there a document that describes what all these files do, which ones I can delete, which ones are vital, etc.?
Thanks in advance!

You need call another PHP file
<?php
   $directory = './files/uploads';
   getDirectoryList ($directory);  
   //This function find all the files in the directory
   function getDirectoryList ($directory)
     // create an array to hold directory list
     $results = array();
     // create a handler for the directory
     $handler = opendir($directory);
     // open directory and walk through the filenames
     while ($file = readdir($handler)) {
       // if file isn't this directory or its parent, add it to the results
       if ($file != "." && $file != "..") {
    //$results[] = $file;
     // Delete Files
    $filename = $file;
  unlink($filename); //this delete a file
     // tidy up: close the handler
     closedir($handler);
?>
