FilesPlus, as the Symbian cloud storage manager, has been through many updates in the last six months, culminating in v1.3.0 here, which not only adds full Box.com(/.net) compatibility, it's also now completely free. Plus a number of bug fixes, of course. More below...

I most recently highlighted FilesPlus a month ago, with v1.2.4, but the changelog from that to this, v1.3.0, is:

• Fix WebDAV client to support special characters in hostname
• Fix sort by name, name(dir. first) to sort case insensitivity
• Save sort flag per cloud storage path
• Add BOX client
• Now freeware (though donations welcomed)

Here's FilesPlus in action:

And here's the new Box.com functionality:

You can download FilesPlus for free here in the Nokia Store or here as FilesPlus_installer_515297.sisx. I guess we should expect more low cost applications to 'go free' as the Symbian ecosystem starts to wind down? Handy not just to save a quid (which is neither here nor there) but to simplify re-installation in years to come should something happen to the developer or the Nokia Store itself.
