Most of the web hosting company does not provide unlimited FTP spaces. In order to monitor the usage, you can login to web-based control panel and view the usage statistics.
Another handy method would be to use PHP to compute the folder sizes. The following is a function to recursively compute the size in bytes for a web-folder. Of course, base on this function, you can easily create events of notification (such as sending emails when usage is high).
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | function dirsize($dir) { @$dh = opendir($dir); $size = 0; while ($file = @readdir($dh)) { if ($file != "." and $file != "..") { $path = $dir."/".$file; if (is_dir($path)) { $size += dirsize($path); // recursive in sub-folders } elseif (is_file($path)) { $size += filesize($path); // add file } } } @closedir($dh); return $size; } |
function dirsize($dir)
{
@$dh = opendir($dir);
$size = 0;
while ($file = @readdir($dh))
{
if ($file != "." and $file != "..")
{
$path = $dir."/".$file;
if (is_dir($path))
{
$size += dirsize($path); // recursive in sub-folders
}
elseif (is_file($path))
{
$size += filesize($path); // add file
}
}
}
@closedir($dh);
return $size;
}Another simpler solution from realmag777 that utilities the latest PHP language feature:
1 2 3 4 5 6 7 8 9 10 11 12 13 | /* * * * Get the directory size * @param directory $directory * @return integer */ function get_dir_size($directory) { $size = 0; foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file) { $size += $file->getSize(); } return $size; } |
/* * *
* Get the directory size
* @param directory $directory
* @return integer
*/
function get_dir_size($directory) {
$size = 0;
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file) {
$size += $file->getSize();
}
return $size;

Here is more simply:
/* * ** Get the directory size
* @param directory $directory
* @return integer
*/
function get_dir_size($directory) {$size = 0;
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file) {
$size+=$file->getSize();
}
return $size;
}
