Koofr desktop client update

We've made some improvements and fixed a few issues in the Koofr desktop client and released a new version.

The update brings these changes:

  • Windows tray icon no longer disappears as it used to after some time.
  • We now prevent syncing of files that have names ending with a dot on Windows, because Windows is unable to open them or delete them.
  • Sync trash is automatically emptied. Files that are older than 14 days are automatically deleted.
  • And lastly, the update also brings various sync bugfixes.

You can let us know what you think of the new release on our Reddit channel.

Koofr app 3.7.4 for Android released

We've made an improvement to the Koofr Android app and released the 3.7.4 version.

This release brings you a single bug fix which prevents Android from killing uploads lasting longer than ten minutes.

The new release is available on Google Play.

We apologize for the prior inconvenience if this bug hit you and, like always, you can let us know what you think of the new release on our Reddit channel.

Maintenance October 3 at 10.00 CET - finished

October 3 15:10 update:

All maintenance work has been completed successfully. As planned, there were no interruptions during the operations.

Original note:

On October 3, from 10.00 to 14.00 CEST, Koofr will be performing maintenance and upgrades on various infrastructure parts, to provide an even better service for everyone.

Maintenance and upgrades will be released in a rolling matter, which means no interruption of our service is expected. Users may experience some momentarily interrupted connections as network changes are applied in the backend.

If you do experience any occasional hiccups during our maintenance window, we apologize in advance.

We will update this changelog as work progresses.

Self-care invoicing upgrade

Due to an increasing demand, EU businesses can now get a proper VAT invoice issued automatically when upgrading an account. This means you will be able to use the same payment options and quick self-care upgrade route as other users, and still get a valid VAT invoice for your company.


Until now, you needed to go through support to get such invoice issued, but since this week, you will be able to make a purchase the same way as end users. Thank you all for being our loyal customers.

IMPORTANT: Amazon discontinues access to Amazon cloud Drive

On Friday, 6.9.2019, we (and many other services) got notified by Amazon, that they will no longer allow third party applications connecting to their Amazon cloud Drive API from 25. September 2019 onward.

This means, that all Amazon connected drives in Koofr will stop working on that day. Unfortunately, this is a decision Amazon has made, and we have no way around it.

This change will in no way affect any other cloud connection (Dropbox, Google or OneDrive) or Koofr as a whole. You will still be able to use your Amazon Cloud Drive through Amazon's applications, but all third party applications will stop working.

What this means for Koofr users with Amazon drives connections?

  • We will first disable the option for connecting new Amazon drives into Koofr in the following days.

  • All existing connections will continue to work, until Amazon shuts down access (probably on 25.9.2019).

  • After that happens, you will no longer be able to access Amazon drives from Koofr, and you can expect any existing public links to files hosted there to fail and display an error page.

  • Afterwards, all such links and devices will be automatically removed from our service, as they will no longer work.

  • If there are any files you have on Amazon and would like to keep accessing through Koofr, we suggest you copy them to Koofr storage or some other external cloud before the 25. September 2019.

Update from Amazon on 16.9.2019:

They have extended the period, the connected drives will now apparently work until November 2019. See both notes below.

Below, find the original note we got from Amazon:

Your integration to Amazon Drive’s API will be discontinued


On September 25, 2019, Koofr's integration to the Amazon Drive API will be discontinued. Customers of Amazon storage will continue to have access to their content through our first party applications for Amazon Photos and Amazon Drive. Please make arrangements to discontinue all traffic to the Amazon API before September 25, 2019.

Sincerely, The Amazon Drive team

Second Email:


We emailed you on September 6th to inform you that Koofr's API integration with Amazon Drive would be discontinued on September 25, 2019. Given the difficulty of transitioning on this timeline, we are extending access until November 8, 2019. This should allow more time for your users to retrieve their content from Amazon Drive using your application. We will also be emailing any user who has uploaded content with your application, in an effort to make them aware of the upcoming deactivation, and to give them an opportunity to retrieve their data.

We apologize for the impact this has on your application, and thank you for being a developer on our platform.

Koofr search improvements

We’ve made some major changes to our search algorithms. So, what’s new?

  • We now support search in languages using non-Latin scripts (e.g. Japanese, Chinese, Korean, Thai, Arabic etc.)
  • We implemented exact search, meaning you can now search for the specific phrase by putting quotes around the text (if you search for the phrase “my cute cat” our search will find all files with this phrase in their name, but only those which have the exact same word sequence to the searched phrase). You can use exact search and normal search in the same query.
  • You still have to use at least three characters when using search. Since quotes also count as characters, you can use one character when you put it in quotes (see picture below).
  • We fixed a bug in our search, which sometimes affected search results not appearing when they should have.
  • We implemented accent-folding, meaning if you search for the letter "o" our search will also find "ö" and all other variations of the letter and vice versa.
  • And lastly, we improved our search results ranking, meaning we made sure you will get the most relevant search results at the top of your search results window.


Koofr desktop client update

The Koofr desktop client has recently undergone a major update. We’ve made some big changes to our syncing process.

So, imagine you are inside your default Koofr sync folder (or any other sync folder that you yourself created for that matter) and you want to copy/move a file. Previously all of the files you copied or moved inside the sync folder were uploaded to Koofr servers again which made the desktop client slow sometimes.


Now we are able to detect that you moved/copied your files and we do the move/copy action inside your Koofr sync folder locally without doing the unpleasant intermediate steps which used to hinder our speed. We improved transfer speed and Koofr now also uses less bandwidth. Or in other words - the Koofr desktop client is now faster.

And then we also have a bug fix for you. Some Koofr on Windows users occasionally had issues if they were using two syncs – for example one from the home office and the other from work.

If they renamed a folder on one of them, Koofr sync would rename the folder but it would also keep the empty copy of the original folder. We are happy to report that we have now fixed this annoying issue.

Koofr space usage tool

We are happy to announce we’ve added a new tool to Koofr EXP.

Koofr space usage tool will do a size analysis of everything you have in your account and give you the information on the space usage, size of each folder and the number of files inside each folder in your account.


From now on you can find it next to our Koofr duplicate file finder. koofr_exp.PNG Note: Koofr EXP are only available in the paid Koofr accounts.

Koofr YouTube channel

From now on you can follow the Koofr YouTube channel, and we are super excited about it.

At the same time, we are also launching the Koofr video guide series, where we will try to explain Koofr features through video tutorials.

We are starting with beginners issues, but we are also planning on doing some more advanced tutorials in the near future.

Our first video explains how to sign up for a free Koofr account - check it out below. And don't forget to subscribe to our channel.

Desktop client and gallery improvements

We’re happy to announce that we fixed a few issues that unfortunately occurred in our desktop client:

  • We fixed the hibernation issues on macOS (changes were previously not always detected after wakeup and you had to restart sync manually).

  • We fixed the network drive issue (there were cases where the enable button in the settings of our desktop client didn’t work if you had any other network drives previously added to your system).

We also made improvements to our HEIC and video thumbnailing machinery. Due to increase in such files, our gallery just could not keep up with it anymore. So it would sometime act really slow. We made sure it does not anymore.
