    Mountain Duck makes the process of working with cloud storage on your local device quick and easy! It is one of the most convenient ways of mounting cloud storage from services including Amazon S3, Backblaze B2 and Dropbox as a drive on your Windows Or MacOS device and once mounted this storage can be used as if it were a locally attached hard drive.

    The main benefit of this approach to adding storage is that the amount of additional disk space available to your device is virtually unlimited, add into this that you data is (potentially) much safer in the cloud, much easier to work with across multiple devices and much easier to share with others. There are also benefits in that should you loose you device (or it becomes unusable in any way) the cloud storage will still be safe and ready to use on another device!

    As well as making cloud storage easy to work with, Mountain Duck also includes the Cryptomator encryption technology which means the setting up of secure, zero knowledge encrypted containers very easy and convenient. This encryption technology is especially useful if using a cloud storage provider which doesn’t offer zero knowledge security in any way themselves and might be used for storing potentially sensitive data.

    So far Mountain Duck looks really promising and the concept of using cloud storage locally has lots of benefits. I also like that Cryptomator has been integrated right into the app itself making it easy to secure you data whilst being stored on any cloud, let’s go and see what it can do!

    Mountain Duck Usability

    In this section of the review I will be looking at Mountain Duck in more detail, starting with the installation process and then looking at the application and its core features in more depth.

    Installing Mountain Duck

    Installing Mountain Duck begins by heading over to the Mountain Duck website where a 14 day free trial version can be downloaded. At just over 65MB the installer can be downloaded and set running very easily, a restart was required during my install although, overall, the process was both quick and easy.

    Very little user intervention was required during the install, just a couple of clicks and then the application was ready to use after the restart. When starting Mountain Duck for the first time we will be asked to provide a licence key or, alternatively, request the 14 day trial.

    With the licencing or free trial out of the way the application itself will now be ready to use!

    Mounting Cloud Storage with Mountain Duck

    Now we have the application installed and ready to use we can start mounting some cloud storage on our device, I will be using Windows 10 during my testing but Mountain Duck also provide a MacOS version of the software for those on Apple devices.

    Upon first opening the software we will see a blank form for configuring the details of our first cloud storage drive, the drop-down menu at the very top allows us to initially specify which cloud service or protocol we want to make use of.

    mountain duck available cloud providers

    For the purposes of testing I will be using Dropbox, but it is interesting to see that a good selection of commonly used cloud storage providers are supported including:

    • Amazon S3

    • Backblaze B2

    • Google Cloud Storage

    • Microsoft Azure Blob Storage

    • Microsoft OneDrive

    • Google Drive


    • Plus others!

    In addition the above, commonly used, services we also see support for using FTP, FTPS, SFTP (SSH secure file transfer) and WebDAV, together making potentially many more storage sources available for use with Mountain Duck.

    Having seen this impressive list of supported cloud storage, let’s get on with the task of configuring a mounted drive using Dropbox. I will start by selecting “Dropbox” from the available storage menu at the top of the configuration screen and then, just below this, give this new drive a nickname so it is easy to recognise which storage is in use.

    As can be seen above, the URL for the service is automatically added for us when using Dropbox, this means we can now move on to optionally setting a path for pointing to a specified folder within the cloud storage (or leave blank to mount the entire cloud drive).

    Next, we can move on to setting the drive letter, this is basically the letter upon which the mounted cloud storage will be accessible from within Windows.

    Finally, we can set the “Connect Mode” and “read-only” options for this connection. The connect mode allows us to specify how the synchronisation of the mounted drive works in the background and the read-only option allows making any mounted files read only (this being read-only from the device in use, not read only on the cloud storage platform itself).

    The two important connection modes available to us are “Online” and “Smart Synchronisation”. The “Online” option does not take up any local disk space on our device, however, it does mean that files are only accessible when an internet connection to the storage provider is active. The “Smart Synchronisation” option makes some files available for offline use depending upon when they are being used or otherwise specified as being available offline, specifying files as available offline can be done after the cloud storage is configured by using the Mountain Duck context menu which is shown below:

    mountain duck make files available offline

    For my testing I will stick with the “Smart Synchronisation” option and omit the read-only flag as I intend to use this new storage as if it were locally attached for testing purposes.

    With these settings complete we can now move on to the next step which is authenticating Mountain Duck to connect to our chosen cloud provider. This authentication process will, of course, vary depending upon the cloud storage provider being used and their own security protocols.

    mountain duck authenticate with dropbox

    As can be seen above, when using Dropbox we are taken to a page to authorize Cyberduck (the developer of Mountain Duck) to have access to our Dropbox account. This process involves logging into Dropbox and then copying an authorisation code to the Mountain Duck box which appears asking for such a code at this time.

    With the authentication complete we will be ready to start using our cloud storage locally on our device, the new virtual drive should now be available to see within Windows Explorer using the drive letter we specified earlier on.

    Performance Issues

    With Mountain Duck making use of cloud storage we need to be aware of any performance issues which might crop up and potentially cause us problems working with our files. Such problems will almost always be linked to slow or unreliable internet connections and, in-turn, probably affect larger files much more than they might smaller files.

    mountain duck review - systray menu

    With the above in mind, it is great to see Mountain Duck comes with a very useful system tray tool which, amongst other things, helps us see the synchronisation status of any cloud storage drives we might have attached. By being able to see the synchronisation status and, if needed, easily detach or re-attach any drives which might be causing connection troubles, we can more effectively manage our storage and internet connection.

    The system tray tool also allows us to get to the main application preferences window which I will look at in more depth in the next section.

    Advanced Settings

    Mountain Duck is a very focused tool and with the mounting of cloud storage aside offers little other functionality. Having said this, once we reach the preferences menu we can fine-tune how the application works and set-up many advanced settings to get the most from our cloud drives in the process.

    mountain duck preferences window

    This preferences window can be opened up via the Mountain Duck system tray utility (found at the bottom right of a Windows system), once loaded up we will have access to many advanced settings including the synchronisation, bandwidth and encryption options used by the app.

    Starting off in the “General” tab (as is seen above) we can set some of the most important settings relating to logging into the cloud services in-use. By default the application will save authentication details and automatically log into and mount any cloud drives for us when logging into our device, in this General tab we can leave this as is or alternatively turn some or all of this functionality off.

    Moving across to the “Sync” tab we can switch between working in the “Online” mode (which doesn’t store any files locally) and the “Smart Synchronisation” mode which allows certain files to be cached locally on the device.

    Other tabs including the bandwidth tab, which lets us potentially limit the bandwidth being used, the “Cryptomator” tab which allows for setting encryption and a couple of other tabs allow us to have very good control over how this application actually goes about doing its job.

    Whilst, as I mentioned earlier on, this is a very focused tool we are still given a good level of control over how it works and can configure it for our individual circumstances, e.g. if we have a slower internet connection we can make use of caching and bandwidth limiting and also make use of the Cryptomator vaults if we have sensitive data to store.

    Other Things to be Aware of

    I just wanted to append a small section to my review to make any potential Mountain Duck users aware of two things which could potentially be an issue when using such a tool, these are cloud storage costs and network connectivity issues.

    Since we are relying heavily on the internet when using such a tool you will need to be aware of what happens if, for example, your internet connection suddenly becomes unavailable! Of course, you could set Mountain Duck to cache some or all of your files locally which means you can then still work on them during any network outage and they will then auto-update with the cloud when the network connection is restored, but this is still something to think about!

    The other important thing to think about is the cost of cloud storage and how this might affect you. Whilst some providers issue a fixed allocation of storage for a fixed cost (e.g. Google Drive) other providers such as AWS S3 is priced per GB / per month, this means, basically, the more your store with such providers the more you will end up paying (so please keep a check on this and make use of any cloud budgeting tools if available).

    Setting-up an Encrypted Vault

    To configure an encrypted vault we must first have a cloud drive configured and mounted on our PC. Once at this stage we can begin by opening our virtual drive within Windows Explorer and then right clicking where in the drive and opening up the Cryptomator window from the menu (as can be seen below).

    mountain duck - new encrypted vault context menu item

    Once in the Cryptomator set-up screen we simply need to enter a name for the vault and then set a password, after doing this our new vault folder will be created and ready to use.

    Once configured the vault will then be controlled, again, by the Mountain Duck right-click menu, this is how we will lock and unlock the files in the vault going forwards:

    mountain duck - unlock cryptomator vault

    NB – If you do make use of the vault functionality do not forget your password! This set-up has been configured so as recovery of data is not possible without the password, please beware of this!

    With all of the above in mind the vault can now be used within Windows Explorer in the same way as any other folder given that encryption is done automatically as files are added. A great feature to see and one which definitely helps Mountain Duck stand out as a great tool to have installed!

    Mountain Duck Security

    When using Mountain Duck you are, naturally, somewhat reliant on the security of the cloud storage providers it connects you with. Having said this, the integration of the Cryptomator tool allows users to configure zero knowledge encryption on their data (at the client side) before it is sent to and stored with any third party.

    Even if you trust the cloud provider you are using it might be a good idea to get into the habit of encrypting your data before sending it to the cloud and with Mountain Duck this is easy to get configured and start working with.

    Mountain Duck Support

    Mountain Duck have good support wiki containing good documentation on the product itself. The support pages can also be used to submit a ticket to the support team should further help be needed.

    Mountain Duck Pricing

    Mountain Duck is priced at a one-off $39 for a single, perpetual licence which covers the individual user (regardless of how many machines are in use).

    Discounts are available for volume licence purchases and a 30% discount is also given to premium users of the Cyberduck cloud storage browsing tool (read our Cyberduck review here).

    A 21 day free trial of Mountain Duck is also available by clicking here.

    Mountain Duck Review Summary

    Mountain Duck is a very focused tool allowing various cloud storage accounts to be mounted and used as if they were local dives on you own Windows PCs or MacOS devices. This approach to adding storage to your device means not only will you (potentially) never run out of disk space but also be easily able to work across multiple devices and be safe in the knowledge that you have a copy of your data in the cloud should you lose or be otherwise be unable to use your current device.

    Having a copy of data on cloud storage also means you can take advantage of the features on offer from the cloud provider themselves, for example, creating sharing links or making use of any available historic versioning functionality can be a big help when managing your files in this way!

    Security wise, the inclusion of a built in encryption tool (Cryptomator) is also great to see and allows users of the application to quickly and easily secure their data when using these third party cloud storage providers.

    Finally, Pricing is very reasonable at only $39 per user, regardless of how many devices they make use of themselves. Personally, I think this is very good value software for a one-off $39 fee and it is very commendable to see a developer pricing per user rather than per device (which I feel, in some cases, unfairly penalises people who work across multiple devices for whatever reason).

    Overall a very impressive tool which is fairly priced and makes accessing and working with multiple cloud storage providers quick and easy, a great tool for anyone who is looking to offload more of their workload to the cloud! Well done Mountain Duck!
