Can you post what you have so far so we can understand where the list of filenames is coming from?
franklin52 example would process the vertical list of filenames in you first post either from a pipe or from a file.
e.g. from a file called my_list_of_files :
With ftp only it's probably going to be a three stage process?
1) Get a directory listing of the remote server directory and store it in a file on the local server.
2) Process the stored list to eliminate files which we have fetched already.
3) Fetch the files and record which ones have been processed.

i recently copied 400GB of data from a NTFS drive to a ext4 drive. I want to verify that the data is 100% identical to the original.

scandir
SCANDIR(3) 1 SCANDIR(3)scandir - List files and directories inside the specified pathSYNOPSIS
array scandir (string $directory, [int $sorting_order = SCANDIR_SORT_ASCENDING], [resource $context])
DESCRIPTION
Returns an array of files and directories from the $directory.
PARAMETERS
o $directory
- The directory that will be scanned.
o $sorting_order
- By default, the sorted order is alphabetical in ascending order. If the optional $sorting_order is set to SCANDIR_SORT_DESCEND-
ING, then the sort order is alphabetical in descending order. If it is set to SCANDIR_SORT_NONE then the result is unsorted.
o $context
- For a description of the $context parameter, refer to the streams section of the manual.
RETURN VALUES
Returns an array of filenames on success, or FALSE on failure. If $directory is not a directory, then boolean FALSE is returned, and an
error of level E_WARNING is generated.

+--------+---------------------------------------------------+
| 5.4.0 | |
| | |
| | $sorting_orderconstants were added. Any nonzero |
| | value caused descending order in previous ver- |
| | sions. So for all PHP versions, use 0 for ascend- |
| | ing order, and 1 for descending order. An option |
| | for SCANDIR_SORT_NONE behavior did not exist |
| | prior to PHP 5.4.0. |

EXAMPLES
Example #1
A simple scandir(3) example
<?php
$dir = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);
print_r($files1);
print_r($files2);
?>
The above example will output something similar to:
Array
(
[0] => .
[1] => ..
[2] => bar.php
[3] => foo.txt
[4] => somedir
)
Array
(
[0] => somedir
[1] => foo.txt
[2] => bar.php
[3] => ..
[4] => .
)
Example #2
PHP 4 alternatives to scandir(3)
<?php
$dir = "/tmp";
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;
}
sort($files);
print_r($files);
rsort($files);
print_r($files);
?>
The above example will output something similar to:
Array
(
[0] => .
[1] => ..
[2] => bar.php
[3] => foo.txt
[4] => somedir
)
Array
(
[0] => somedir
[1] => foo.txt
[2] => bar.php
[3] => ..
[4] => .
)
NOTES
Tip
A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen(3) for more details on how to
specify the filename. See the "Supported Protocols and Wrappers" for links to information about what abilities the various wrappers
have, notes on their usage, and information on any predefined variables they may provide.
