SPFileZilla

If you're fed up with having to manage your SharePoint sites and documented using a browser, or you are simply looking for a more lightweight and straightforward solution then, without a doubt, you will find SPFileZilla to be of great worth.

FileZilla-inspired tool for managing SharePoint content

In just a few words, this piece of software allows you to manage your SharePoint content just as you would in the case of any FTP server. That said, you can browse site lists and document libraries, upload and download files, folders and documents, as well as move, rename, and delete them with ease.
Since it borrows all the user-interface goodies from FileZilla, things are quite intuitive, as well. It has the same tabbed UI which allows you to easily navigate through your files, it comes with support for drag and drop, and it allows you to use any number of profiles. To save a profile, pick a profile name and enter the site URL, username, password and the SharePoint domain.

Looks like FileZilla but its specialized

Quite conveniently, there's also a quick connection box, which, as you may have guessed, offers you a more direct alternative of connecting without necessarily having any saved profiles. Right-click any file are you are bound to discover the SharePoint-specific set of menu options. For instance, you can easily move, copy, update files, as well as publish files with no more than a few mouse clicks.
It's also worth knowing that SPFileZilla is compatible with SharePoint 2010 and 2013, as well as with SharePoint Online (bundled with Microsoft's Office 365). To our surprise, the application is also capable of working with OneDrive for Business.

Upload and download files to and from SharePoint with the help of this featherweight and efficient app

To end with, SPFileZilla is a perfect example of what can be achieved thanks to open-source technology. It uses the core and UI structure of one of the best FTP clients out there, and, thanks to a bit of ingenuity, the result comes in the form of a bespoke tool for users who desire a quicker and more effective way of managing and transferring content to and from their SharePoint site.
