Add From Server

Whenever I need to upload media files that are too big to upload directly to WordPress, I FTP them to the server and use this plugin to add them.

Great tool for those big media files you can only ftp to the server

Filenames on the web are different than those on the desktop. Empty spaces and strange characters doesn’t belong to web space. Enter UploadPlus: you can set your rules and clean your files’ name while they upload. Three basic rules:
<ul>
<li>keep only alphanumeric [A-Za-z] and digits, spaces and strange characters stripped out;</li>
<li>convert spaces and strange characters into dashes (-)</li>
<li>convert spaces and strange characters in underscores (_)</li>
</ul>
You can apply website-based or date-based prefix, even a custom prefix. Lowercase or Uppercase? Your choice! 
Some default prefix:
<ul>
<li>time/date based timestamps via PHP date()</li>
<li>blog name/slug</li>
<li>random</li>
<li>and many more!</li>
</ul>
UploadPlus can also transliterate filenames (text conversion from a non-latin script to raw latin characters). 
You can preview settings in the media settings page without uploading files.
