What is COSBrowser?

COSBrowser is a visual interface tool launched by Tencent Cloud to make it easier and simpler for you to view, transfer, manage, and interact with COS resources. Currently, it is available for desktop (Windows, macOS, Linux), and mobile clients (Android, iOS). For more information, see COSBrowser Overview.

How do I download COSBrowser?

For the download URL and instructions, see COSBrowser Overview.

Why can’t I find the storage path when I log in to COSBrowser with a sub-account?

1. Please make sure the sub-account has permission to access COS. See Granting Sub-accounts Access to COS.
2. If the sub-account only has permission to access a specified bucket or a specified directory under a bucket, then you need login to COSBrowser and manually add a storage path (format: “Bucket” or “Bucket/Object-prefix”, e.g. examplebucket-1250000000), and select the region where the bucket should reside.
   

How do I transfer a large number of files at greater speed?

Take Windows COSBrowser as an example. You can do so by navigating to Advanced Settings, and configuring a greater number of concurrent files and parts under Upload and Download.

What should I do if I am prompted that “Update failed. Permission is denied” using macOS-based COSBrowser?

Cause
The above issue may occur when the two files com.tencent.cosbrowser and com.tencent.cosbrowser.ShipIt under the /Users/username/Library/Caches/ directory belong to a root account and a user account, respectively. The resulting permission issue can cause update failure.

Solution
Run the following command on your Mac device:

sudo chown $USER ~/Library/Caches/com.tencent.cosbrowser.ShipIt/

What should I do if I am prompted “no such file or directory, stat 'C:\Users\XXX\AppData\Local\Temp\cosbrowser\logs\cosbrowser.log'”, and cannot use the tool?

Solution: We recommend that you download Version 2.1.x or later.

What should I do if the installation of cosbrowser.exe is aborted automatically?

Cause
This problem occurs when COSBrowser has been installed before, and its traces have not been removed from your system after manual deletion. Therefore, when you reinstall it, the installer aborts the installation as it identifies existing traces but no actual application.

Solution
Manually remove the traces left after the previous installation of COSBrowser, or do so by using a cleaner tool (such as the Software Management tool provided by Tencent PC Manager).
