Baidu Netdisk's speed throttling has always been a headache. As a student, I really can't afford to renew that expensive plan: 30 yuan per month, over 260 yuan per year, and I don't use it much. Yesterday I downloaded a 6 GB software package and it throttled to 100 KB/s, which was really painful. Then I found a method to obtain direct links. Personally tested on campus network with 100 Mbps broadband, it could reach up to 8 MB/s.
How to convert Edge plugins to Chrome plugins, I recommend reading a post by WeiSay titled Chrome browser installing Edge extensions
1: First install the Tampermonkey extension; the installation method is posted above.
2: Then in Edge open the Baidu Netdisk Easy Download Helper URL shown above, install the plugin. Then enable the direct-link plugin.
3: Download IDM; if you don't have IDM, there are many versions available on the WuAi Forum. Of course you can also choose to purchase a yearly license; I bought mine for 22 yuan/year; the official version is also fairly affordable.
4: Configure IDM-related properties. Specifically:
After finishing the settings, click OK to save.

5: Open Baidu Netdisk, first select the files you want to download, click the Easy Download Helper above, then obtain the direct link address.
