S3 Browser options for mac

Most consumer-focused cloud storage services like Dropbox or Google Drive come with their own desktop sync client. S3 differs in that it is primarily driven by an API which you need a client like ExpanDrive in order to take advantage of on your desktop. Amazon provides a fairly basic web interface, but other than that the only way to get data in and out of it is via the API.

There are a wide variety of clients to access S3, like S3 Browser or Transmit for the Mac. DragonDisk used to be targeted on this use-case but development ceased a few years ago.

ExpanDrive provides the same functionality but also turns the S3 into an infinite-capacity external drive. This means Finder and Explorer now have S3 built in, as does every other app on your machine.

Bucket level organization

To get started you load ExpanDrive and input your access key ID as well as your secret key. Connecting mounts the root of your AWS account. Now you can use Finder or Explorer to browse your buckets and then drill into them.

S3 is organized into buckets, which are top-level folders that are uniquely named throughout the service. You can attach various policies to a bucket such as restricting access to particular users or making hosted content available to the public. ExpanDrive lets you mount the root of your S3 account, showing you all your buckets (if your user has permission to list buckets). You can restrict mount a specific bucket, or even a particular folder in a bucket, by typing the bucket name in the remote path section. For additional details you can check out our documentation on connecting to S3. This is useful if you have an IAM user with access to only a single bucket or doesn’t have the permissions to list the buckets for an account.

Browse S3-Compatible storage like Wasabi

Amazon provides a simple guide to get started with their S3 service. ExpanDrive is also compatible with any S3-protocol compatible service like Wasabi or Dream Objects. For Wasabi you modify the server section to https://s3.wasabisys.com and use the Access Key and Secret Key you got from the Wasabi control panel.

ExpanDrive Openstack Mac

Click Save or Connect and you’re good to go. Amazon S3 will now be visible as a network drive whenever you login to your computer – letting you access all of your content from Finder, Explorer, Photoshop, Microsoft Office – whatever!

Drag and drop files to copy them out to the cloud. You can even stream media content like movies and music directly from the S3 storage without needing to first download or sync them. For more information, check our documentation page on connecting ExpanDrive to S3.

Amazon S3 is Amazon’s API-driven, amazingly durable cloud storage service. Launched over ten years ago, in 2006, it was the first offering of what is now Amazon Web Services.

Map S3 as a Network Drive with ExpanDrive

If you’re looking to connect to S3, ExpanDrive is an amazing option. It has been under active development for more than 10 years and is one of the fastest and most reliable S3 clients available. ExpanDrive is a S3 client for macOS and Windows that lets you connect to S3 as a fast network drive. All your files in the cloud are available from within any application including Finder and Explorer.

S3FS for Mac and Windows

Tools like S3FS for linux perform a similar function but lack critical features like background writes, smart synchronization of files for offline access and multi-threaded reads and writes. With ExpanDrive you get a host of extra features and robust performance. Users can access petabytes of data from their laptop as if it was local. ExpanDrive works as a free S3 Client for macOS and Windows that connects you to Amazon S3 as a fast network drive. 

Creating a virtual drive with Amazon S3

Amazon provides a simple guide to get started with their S3 service. You’ll need an AWS account, as well as a bucket. From there, you’ll want to get your API keys to authenticate with ExpanDrive. Haystack Software has a nice guide on how to get the keys. As with any AWS keys, it is recommended to use IAM keys rather than your root keys.

Multiple OneDrive Accounts on Mac or Windows

Microsoft’s office OneDrive client and the Windows built-in client are only able to connect to a single OneDrive or Sharepoint account. This makes sense for most people. If you want to connect to multiple accounts at the same time ExpanDrive for Mac and Windows is an amazing option. You can access your content on demand without needing to sync anything.

Connect Two OneDrive Accounts at the same time

It’s not uncommon for people to have a OneDrive for Business account for work or school and also have a personal OneDrive account on their own. With multiple accounts your only option to move data in and out of both of those is using the browser. This might be fine for occasional use, but any serious user relies on native access to their files. Having on demand access from Finder or Explorer is essential.

Map Google Drive on Mac or Windows

Map Google Drive as a Drive Letter in Windows or macOS

Google Drive is the file storage area for GSuite. It comes with 15GB of free online storage and the extended storage plans have huge amounts of capacity. ExpanDrive is a special type of Google Drive client that lets you map Google Drive or a specific Team Drive as a fast network drive on Windows or macOS or Windows.

Connect to multiple accounts

You can map the root of your Google Drive or an individual Team Drive as a drive letter. You can even connect multiple Google Drive accounts at the same time.

Map specific Team Drive

Let’s say you’re working on a team of people that is all using the same Team Drive. You can map that team drive to its own drive letter by configuring the remote path inside ExpanDrive. All of the team drives are organized in the “Team Drives” folder. If you had a Team Drive named “work” you could mount just that by setting the remote path to “/Team Drives/work” inside ExpanDrive.

Files on demand

Another great thing about ExpanDrive and Google Drive is you can access your entire account without taking up any disk space. Everything is accessed on demand without preemptively syncing data back and forth. So if you were working on a huge Team Drive like in the previous example you could mount that entire space without needing to first sync it to your computer. You can also easily mark files to be available as offline so you can get work done even without an internet connection.

Access Google Drive as a shared drive

ExpanDrive lets you actually mount your Google Drive account as a virtual drive, just like a USB Drive, on Mac or Windows. You can browse and access your Drive account without needing to first sync your files, which takes up time and space on your laptop. Just access what you need, when you need it, from within any app like Finder, Windows Explorer, Microsoft Word, Photoshop, or whatever you use. Everything is safely in the cloud but not taking up space on your computer. Isn’t that the point of cloud storage anyways?

Free up hard drive space

What good is a 10TB account if your only supported mechanism move data is via sync. Jason Snell recently wrote a piece at Six Colors called the Dropbox Terabyte Conundrum about this same problem with Dropbox’s new 1TB plan. Using Sync to move your data means you need to pick a folder that mirrors your Drive account and then keep a copy of all that data on your machine. So unless your laptop have a 10TB Drobo or Synology NAS attached to it, then you can’t really DO much with a 10TB Google Drive account. Unless you have ExpanDrive.

Map or Mount Box as a Network Drive on Mac and Windows

Box.com, like most big online storage providers, provides a Sync client for your desktop PC or Mac.

Box as a network drive

Problems with Sync – It needs lots of hard drive space

To use Box Sync you first have to download all the data to your machine – which takes a long time and can take a lot of storage.  If you’re running a MacBook Air or an notebook with a 128GB SSD it’s going to pretty hard to use your company’s 500GB Box account. Forget trying to store lots of media and assets with Box sync. What you really want is to offload that data to the cloud, but still be able to get at it when you need it. That’s what a network drive like ExpanDrive is perfect for. The files are still there, but they are just stored directly on Box.

Sync is less Secure

Box has a great security model – you can provide fine grained control to your users. When employees leave, you can simply revoke their permissions. However, using Box Sync that model breaks down a bit. Everybody has a copy of the data sitting on their laptop. If the machine is lost or stolen the files remain there for the taking. If an employee runs off, they can still access all the data they had before since it is just sitting in a folder on their computer.

Connect Box as a Network Drive with ExpanDrive

ExpanDrive makes managing your Box account as seamless as using a USB Drive. It also improves the Box security model – ExpanDrive accesses everything on demand. Here is a video to help get a better idea of what ExpanDrive does and how it works.
