On servers there are limit how many files can be placed in a folder. Also FTP clients by default limit some 2000 files per folder.

Having too many files in a folder is difficult to manage, even directory listing take lot of time on folders with too many files.

If you are using muti server function in vshare, it will create folder and remote server and upload video to it.

To disable this, open

include/functions_upload.php

Find

$video_folder = floor($convert_vid / 1000) + 1;
$video_folder = md5($video_folder);
$video_folder = substr($video_folder, 1, 10);
$video_folder = trim($video_folder);
$video_folder .= '/';
Replace with

$video_folder = '';
