ExpanDrive v5.3 is out

ExpanDrive v5.3 is out on the auto-updater and the main download page.

NEW Preliminary support for Sharepoint Online [Office 365 Sites]
NEW Rewritten WebDAV connector
NEW All-new metadata caching layer, bringing faster access and asynchrnous updates of regularly used data
NEW Moved to OneDrive v2 API
NEW Improvements to SFTP layer for speed and large file transfers

For the curious yes, we skipped v5.2 – It was an internal release in testing for an extended period of time that we decided not to publish.

ExpanDrive v5.1.8

ExpanDrive v5.1.8 is now available for Mac and Windows. It’s a relatively minor update that mostly fixes some SFTP and WebDAV compatibility issues.

Release notes can be found here.

ExpanDrive v5.1.3 and OS X El Capitan

Users of ExpanDrive v5.1.3 on OS X El Capitan will need to manually upgrade to a newer version of ExpanDrive by downloading it at ExpanDrive v5.1.3 on OS X 10.11 exhibits a broken auto-updater. Make sure to quit ExpanDrive if you’re already running it. This release was only available for about half a day, so hopefully it doesn’t affect too many users. ExpanDrive v5.1.4 is already available with a fix. Our apologies for the trouble.

ExpanDrive v5.1

ExpanDrive v5.1 is now available for download and via the auto-updater. It includes full support for OS X 10.11 El Capitan and wraps up myriad changes and fixes since our V5 release back in July. You can always get the release notes for each intermediate version over at our support page.

SFTP, FTP and S3 in the Sublime Text sidebar

Sublime Text is an enormously popular text editor for Mac, Windows and Linux. Combining Sublime Text and ExpanDrive is a powerful workflow – you actually edit and manipulate files on SFTP/FTP or S3 in real-time from directly within the Sublime Text. You don’t need to download the file, edit it, and then re-upload it. We use Sublime in conjunction with ExpanDrive every day to develop the Ruby on Rails code that powers as well the ExpanDrive Store. It’s also one of the primary ways we dogfood ExpanDrive.

Try ExpanDrive Free for 7 Days

It’s pretty easy to get started. If you haven’t installed ExpanDrive you can download the latest release here. It’s free to try out for a week and is available on Mac and Windows. These screenshots are from the Mac version, but it looks nearly the same on Windows.

Create new SFTP Drive

We start by creating a new SSH (SFTP) connection within ExpanDrive, although you can connect to FTP, Amazon S3 or a whole variety of other support cloud storage providers if you prefer.

Select Authentication

ExpanDrive affords you a variety of configuration options for SFTP and FTP. We generally use public key authentication combined with Google Authenticator for multi-factor authentication. You can even set a remote path so that you can mount /etc and twiddle configuration files directly.

Server in Finder

Once you have made the connection to the server, the contents are viewable in Finder, Explorer or any other application. On the Mac I like the Open in Sublime button to click a folder and then click Open in Sublime and have Sublime open up the tree as a project. This is easier on Windows where you can right click and have the default shell extension offer “Open in Sublime.”

SFTP in Sublime Sidebar

Now you can edit any file directly within Sublime and have the entire tree visible in the sublime sidebar. While there are some other options out now for accessing SFTP servers from within Sublime, I feel pretty confident that ExpanDrive is the best. We have rock-solid background saves that let you hit command-s [or ctrl-s, if you’re on windows] with abandon. You’ll experience no delay as the file is saved instantly and pushed out to your server in the background.

ExpanDrive v4.3.1

ExpanDrive v4.3.1 is out on the auto-updater. This is a small bug fix release that does a lot to improve compatibility with MS Office 2013 saving to S3 and Swift connections. S3/Swift don’t allow you to set the modification time of a file, and in certain cases Office with get confused and suggest somebody else edited the file. This fix also incorporates a change for parsing dates in Swift that does a better job accounting for time zones.

New in v4.3.1

  • CHANGED Improved support for editing MS Office documents on Swift and S3
  • FIXED Fixed timezone issue on Swift.

ExpanDrive v4.3

ExpanDrive v4.3 is out on the auto-updater. It adds support for NTLM authentication to improve compatibility with Sharepoint installations as well as improves support for versioning in Google Drive and connections.

New in v4.3

  • NEW Support for NTLM authentication for Sharepoint, etc.
  • CHANGED Improved support for versioning on Google Drive and Box
  • FIXED Fixed timezone issue on Google Drive.

ExpanDrive v4.2 adds OneDrive for Business/Office 365

We’re excited to add support for Microsoft OneDrive for Business, part of Microsoft’s Office 365 suite of products. OneDrive of Business is the enterprise version of Microsoft’s online storage service and offers unlimited storage at no additional cost. With ExpanDrive you can connect to your OneDrive account directly from within Finder, Explorer or any other app on your computer.


Mac users should be particularly excited since Microsoft still has no Mac App for OneDrive for business. ExpanDrive is currently the only game in town! You can download ExpanDrive v4.2 at or using the ExpanDrive auto-updater

SwiftDrive – Mount OpenStack Swift as a Drive on Mac or Windows

OpenStack Object Storage, also known as Swift, is the emerging leader for open-source distributed object storage. Swift lets you run a service much like Amazon S3 atop your own hardware, behind your firewall, controlled by you and your organization. ExpanDrive natively supports the OpenStack Swift API and lets you mount your cluster on Mac or Windows just like a network drive – a SwiftDrive. This lets you move data to and from the object store using your existing workflow, your existing applications and your existing business procedures.

Object storage is not a drop-in replacement for existing RAID arrays and other legacy storage products. You can’t just mount a petabyte Swift cluster using SMB/CIFS. There are some gateway products that are starting to emerge, they are an intermediate solution at best. With ExpanDrive you can directly connect to and browse your Swift install right from within Finder, Explorer or any app on your Mac or PC. You can easily offload data or pull in data that is in cold storage.

Here is a video to help get a better idea of what ExpanDrive does and how it works.

Getting started with ExpanDrive and OpenStack Swift is easy. We support Swift V1 authentication as well as Swift V2 Keystone authentication. Install ExpanDrive and create an OpenStack Swift drive type – you’ll then enter your credentials on a screen that looks like this:

ExpanDrive Openstack Mac
If you enter in a keystone server in the server field [a URL that ends with v2.0] you’ll also see a field to enter your tenant information. Click Validate Credentials to see which storage endpoints you have access to and click connect. You’ll now see a new drive attached to your machine that is directly connected to Swift.

ExpanDrive v4.1.9

ExpanDrive v4.1.9 is out on the auto-updater. Most notably it fixes an issue that cropped up on the Mac with Dropbox authentication. Upcoming v4.2 will add OneDrive for Business and Azure support as well as improve the write-behind cache further.
