WP Easy Uploader is a great WordPress plugin, it allows an Administrator to add plugins, themes, and any type of file to WordPress directly from inside WordPress. You no longer have to load up an FTP client just to try out that latest plugin or to upload a text document for people to download. You not need to sign-in to your ftp account for file uploading. WP Easy Uploader is a web based ftp client.

Features:

• Upload any type of file to either the standard Uploads directory (just as images do when you are creating posts and pages) or to a path of your choosing.
• Manual paths are automatically created if they don’t exist.
• Easily upload plugins directly to the plugins directory and theme files directly to the themes directory.
• You can select to have archives automatically extracted to their destination. This means that plugins and themes will be taken care of for you, but it also means that you can zip up a large set of files and upload them quickly into a folder on your site. Currently zip, tar, gz, tar.gz, tgz, and tar.bz2 archives are supported.
• Options for overwriting existing files, renaming the fle if a file with that name already exists (or if overwriting fails), removal of the archive after file extraction, and forcing extracted files to be contained in a folder.
