Chrome OS: a file manager for Linux? [A]

Introduction

Maybe you wonder if there isn’t something like the File Explorer of Windows 10 or the Finder of macOS for the Linux of Chrome OS?!

In other words: a comfortable file manager and, if possible, of course, in your native language? No problem! Starting with this post, I will describe one of many available representatives: the Double Commander.

How to install Double Commander in the Linux of Chrome OS? [A]

The installation is quite simple. The requirements are that you 1) have activated the Linux of Chrome OS (I have described the procedure in this post), and 2) have installed a graphical App Store for Linux. I have also described this in this blog. Here you can find the installation of the Gnome Software Center and here the installation of the KDE Discover.

Professionals can use the terminal to install Double Commander via apt:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install -y doublecmd-qt

If all requirements for the graphical way are met, Double Commander can be found in both App Stores and installed with a few clicks. You have the free choice! I have used the latter as an example here. You can search for it directly in the launcher and launch it from there:

In KDE Discover, simply enter “Double Commander” in the search box in the top left corner and click “Install” on the right:

After installation, you should restart your Chrome OS device once and then start the Terminal or another Linux application so that the Double Commander icon appears in your launcher.

Is the Double Commander displayed in English, and you want to change the language to your native one? No problem!

How to change the language of Double Commander in the Linux of Chrome OS? [A]

Then you click on the “Configuration” item at the top of the menu, a dialog opens. In this dialog, you will find the entry “Language“:

Simply click on your native language here and confirm with “OK.” Then you will be asked to restart Double Commander once to make the changes take effect. Also, close this request once with “OK.” Then close the program window and start Double Commander again from the launcher.

Now the application is displayed in the language you’ve selected in the configuration:

How to change the attributes of a file in the Linux of Chrome OS? [A]

Sometimes it is necessary to change the attributes of a file. For example, if it’s read-only or if you want to make it executable. That is the case if you have downloaded an application in the form of an AppImage package and want to make it executable. To do this, you must mark it as “Executable.”

Use Double Commander to navigate to your file and right-click on it by pointing directly at it and pressing the right mouse button:

In the dialog that then appears is the tab “Properties.” On the second tab of the file properties dialog, you will find the tab “Attributes” which is interesting for us:

There you can set a checkmark at “Execute” and implement this with “Set to all selected files.” (Sorry about the screenshot. “Set properties” is marked instead of that.) Then you can close the dialog with “Close.” Now the file from “Executable” is set up.

How to launch an AppImage package in the Linux of Chrome OS with a double click?

Use Double Commander to navigate to your AppImage package.

If you have made the file executable as described above, you can now start it by double-clicking it:

Of course, there are many other things you can do with the Double Commander, but this is going too far here.

ksnip is a little screenshot tool that I use when blogging, for example, to annotate images. You can see the result here in the post in the pictures. With ksnip, this is very easy and fast.

If you are interested, you can have a look at my blog, chrome your startup. There I just started a series called “Everything you need to know about blogging on Chrome OS.”
