A decent S3 bucket manager for Ubuntu

Why a separate file manager when there is s3fs, which makes it possible to mount S3 buckets via fuse?

That way you won't notice any difference between local files and your S3 bucket in nautilus.

TL;DR CrossFTP is in the Ubuntu app store, you must "buy" it for the purchase price of $0.00. So an Ubuntu One account is required, to install that way. For a mountable file-system try S3QL, which is available through a PPA.

Okay, it seems part of the confusion with s3fs is that there are THREE of them with mostly the same name with varying levels of development and stability. However, S3QL appears ready to go and slick. Another one worth checking out is s3backer.

For a GUI, I'm using CrossFTP. I've also installed dragondisk, but I personally need to access a custom (Dreamhost Objects) S3 server (non-amazon). S3QL will do that for you as well as CrossFTP. WARNING: CrossFTP is "open-core" software, though it is worth it!

Three similar packages that you shouldn't worry about (development has mostly stopped on all but the one noted)

• FuseOverAmazon (previously s3fs)
• s3fs-fuse
• s3fs
• s3fs

Wouldn't it be nice if that list was full of links so you knew what the heck I was talking about? Well, stackexchange won't let me post more than 2 links because I don't have enough rep points. How am I supposed to get them if I cannot be informative? :( The TL;DR part is the most important. You can look up open-core in wikipedia, another link I wasn't allowed to post!

DragonDisk is a decent Amazon S3 GUI client for Ubuntu.
