Easily synchronize your Chrome OS devices with OneDrive: Autosync for OneDrive [A]

Introduction

Since the internal storage of Chrome OS devices is often limited, I’ll show you here how to synchronize your Microsoft OneDrive with mostly larger external mass storage devices!

Autosync for OneDrive is an Android app that is capable of synchronizing your cloud storage with your internal and external storage.

There are some restrictions in the free, financed by advertising version: The number of folder pairs you’re allowed to sync, the allowed file size, and the use of multiple accounts are, among other things, limited. For a few bucks, you can unlock these restrictions to varying degrees.

If you want to test and understand what I am describing to you now, the limited version should suffice.

Setting up the App

If you’ve installed the app from the Play Store, a few steps are necessary before you can start the first synchronization.

Signing in to your Microsoft account and OneDrive is quick and easy:

How to set up a folder synchronization

If you now choose the option that you want to set up your first folder pair yourself, you can start right away!

Now you have to grant the app some rights first:

If you don’t allow the following access request, the app won’t work:

Tip: If you have the free and restricted version and are not sure whether the restrictions apply to your folder contents, you can simply choose the β€œtest folder pair.β€œ

Click in the field below “Folder in OneDrive” :

Then navigate to a source folder in “My files” or “Shared with me“:

The following folder, for example, is in my “My files” folder:

Confirm your selection with the β€œSelect” button.

Repeat this for a destination folder by clicking on the field below β€œLocal folder on device” :

You can now select your internal and external data media here. However, you may have to grant the app extended access rights. So, if you get corresponding messages, you would have to confirm them and agree to the permission requests. If you want that, you can skip the following section.

I’ll explain how you can control this directly via the settings in the next section.

How to grant access to external storage to the app

At the top right of the app, there is a button with four dots stacked on top of each other. If you click on them and select “Settings” in the context menu that appears, you can open them:

Setting up AutoSync for OneDrive on Chrome OS β€” step 10 | Image: cyldx.com

Under β€œFiles and folders” you will find an option β€œWrite access SD cards” for granting extended access rights to external storage such as SD cards:

Setting up AutoSync for OneDrive on Chrome OS β€” step 11 | Image: cyldx.com

In the dialog that opens, you can see the status of the write access:

Setting up AutoSync for OneDrive on Chrome OS β€” step 12 | Image: cyldx.com

As you can see in the screenshot, I already have a folder shared. But now I want to allow write access to an external storage, just like you do. To do so, you have to click the β€œAllow write access” button. Before you start, the app will inform you about how to allow write access:

Setting up AutoSync for OneDrive on Chrome OS β€” step 13 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 13 | Image: cyldx.com

The link β€œOnline User Guide” refers to what, I think, is an old article about SD card access from older Android versions. With β€œPERMIT WRITING ACCESS,” you close the info dialog, and I describe here precisely how to proceed:

Setting up AutoSync for OneDrive on Chrome OS β€” step 14 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 14 | Image: cyldx.com

On the left side, you will now see your internal and external storage. A USB symbol in front of the line highlights external storage. For me, that’s an external 1 TB USB-C-SSD. For you, it perhaps is an SD card, a USB stick, or a USB hard disk. All these possibilities are supported here. You just need to format them in a format that can be read by Android apps on Chrome OS, such as exFAT.

If you now select the desired data medium by clicking on it, the following dialog appears:

Setting up AutoSync for OneDrive on Chrome OS β€” step 15 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 15 | Image: cyldx.com

Here the contents from the top level of the selected medium (the root directory) are displayed. You have to select exactly this top-level with “SELECT” to grant write access to it successfully.

In most cases, that should work flawlessly. The result of this procedure is shown here again:

Setting up AutoSync for OneDrive on Chrome OS β€” step 16 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 16 | Image: cyldx.com

You can then use the β€œleft arrow” button at the top of the left-hand side to go back to where we came from, namely to set up a folder synchronization.

How to complete it is explained in the next section!

Completing the setup of the folder synchronization

Just a reminder:

Setting up AutoSync for OneDrive on Chrome OS β€” step 17 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 17 | Image: cyldx.com

That’s where we come from! You had already set up the folder in OneDrive.

Now navigate to a destination folder on the external data medium to which we have just granted write access.

And there, for instance:

Setting up AutoSync for OneDrive on Chrome OS β€” step 17 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 17 | Image: cyldx.com

If it doesn’t exist yet, you can create it by clicking on “Create order.” Autosync supports you in this process and automatically suggests the name of the source folder as name:

Setting up AutoSync for OneDrive on Chrome OS β€” step 18 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 18 | Image: cyldx.com

Of course, you can change this as you like. When you’re finally satisfied with the name, click on β€œCreate.”

Then you land directly in the new destination folder:

Setting up AutoSync for OneDrive on Chrome OS β€” step 19 | Image: cyldx.com

Now confirm your folder pair with the “Select” button.

You will then be shown an overview of your previous configuration:

For the synchronization method, “Up- and Download” is preselected as default. That means that no matter where (cloud or local) a file is created, modified, or deleted, synchronization takes place in both directions. If you don’t want that, you can change it as you like.

You can now save your folder pair by clicking the “SAVE” button. Then an overview of all your configured β€œSYNCED-FOLDER” will appear:

Setting up AutoSync for OneDrive on Chrome OS β€” step 21 | Image: cyldx.com

If you now click on the sync icon, Autosync will immediately start synchronizing the contents of the folder pair.

How to set up an automatic background synchronization

With the default settings, an automatic synchronization takes place in the background, continuously repeating itself:

Setting up AutoSync for OneDrive on Chrome OS β€” step 22 | Image: cyldx.com
Setting up AutoSync for OneDrive on Chrome OS β€” step 22 | Image: cyldx.com

You can disable that in the settings if you want.

Attention: If you switch between your devices, the background synchronization will take some time. So don’t worry if it seems at first that your latest changes are not yet visible on the other device!

Tip: If you want to increase the speed of synchronization, it’s better to create multiple pairs of folders, so you don’t organize all your files into very, very few folders.

If your destination folder has enough space for the data from the source folder, this should always work successfully.

You can view the status of the last synchronization here:

Are you interested in details, or do you want to check if there were any errors? Then open the “SYNC HISTORY“:

By the way, there is also a variant of the app for Google Drive. I’ll show you how this works in another post. The setup is pretty much the same.

How to access the synchronized files?

With the Files app of Chrome OS

Of course, you can easily access your synchronized files with the Files app of Chrome OS:

For example, you can open PDF documents directly with the Chrome OS PDF application:

With an Android app

With Android apps, you can also find the files. So, for example, you can open PDF documents with the Adobe PDF Reader app:

Opening a PDF-file with Adobe PDFAndroid App on Chrome OS | Image: cyldx.com

Here the opened PDF file:

Opening a PDF-file with Adobe PDFAndroid App on Chrome OS | Image: cyldx.com

However, you may also need to allow file access for the respective app.

Attention: Not all Android apps can do this because they have implemented read and write access to external data sources differently. Some Android apps, such as our Autosync, can modify files without restrictions. But some apps can only read files and not write them!

With applications in the Linux mode of Chrome OS

You can right-click to share folders with the Linux of Chrome OS so that you can get access to your synchronized files from there too:

Sharing a folder synchronized with Autosync for OneDrive for the Linux Mode of Chrome OS | Image: cyldx.com

You’ll have to confirm that here, just to be safe:

Sharing a folder synchronized with Autosync for OneDrive for the Linux Mode of Chrome OS | Image: cyldx.com

Then you can also find your synchronized files in the Linux of Chrome OS.

Here is an example of the file manager Double Commander, which I introduced to you in this post.
