Double Commander is a free cross platform open source file manager with two panels side by side. You can easily explore, download and edit any file on your Synology NAS. In this step by step guide I will show you how to install Double Commander on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Double Commander v1.1.22 release.

💡Note: Check out my new guide on how to Install Double Commander Using Portainer.

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it doublecommander. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create two new folders inside the doublecommander folder that you created at STEP 3. Name them config and data. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 5

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the image below.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 10

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:3278 If everything goes right, you will see the Double Commander Login page. Type in your own CUSTOM_USER and PASSWORD that you have previously created at STEP 6 then click Sign In. Follow the instructions in the image below.

• STEP 11

Your Double Commander dashboard at a glance!

• STEP 12

Click sata1. You can easily explore all folders and files on your Synology NAS. Follow the instructions in the image below.

• STEP 13

If you want to uninstall and remove the doublecommander folder that you have previously created at STEP 3, follow the same exact STEPS in this article from STEP 18 to STEP 22.

Enjoy Double Commander!
