Baidu PCS Go Web Edition Background

BaiduPCS-Web， It is a third-party Baidu download tool that supports the most platforms, and supports Windows Mac, Linux and Android.

When you use Baidu online disk, you should be moved by the download speed
After other online disks withdrew from the free market one after another, Baidu online disk is basically in a monopoly position in the market at present, and a large number of files are shared through it, so you can't use it if you don't want to

Open members can slightly ease the speed of the tortoise, but I don't think it can meet the needs of users very well, so a large number of third-party online disks appear, such as speed disks, oil monkey scripts, etc.
