Take COSBrowser for Windows as an example. You can navigate to Advanced Settings, and configure a greater number of concurrent files and parts under Upload and Download.
You can copy a file link as follows:
Note:
- If public read is enabled for the file, you can use an unsigned link, i.e., object address (valid permanently) to access it.
- If private read is enabled for the file, you must use a signed link to access it. You can customize the link validity period in the Copy Link window, which is 2 hours by default.
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 failures.
Solution
Run the following command in Terminal on your Mac:
sudo chown $USER ~/Library/Caches/com.tencent.cosbrowser.ShipIt/
Solution: We recommend you download v2.1.x or later.
cosbrowser.exe
installation is interrupted?Cause
This problem occurs if COSBrowser has been installed before, but 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 use a cleaner tool (such as the Software Management tool provided by Tencent PC Manager).
The DNS error indicates that the COS domain name failed to be resolved in your local network. We recommend you change your local DNS server address to a public one such as 114.114.114.114
and try again or change the network environment for testing.
