this method actually from same author / creater of method 3, but they have developed something new. all u need to do is access https://pan.baidusu.com , then copy & paste shared link on first row and password on second row. then it will show all files from that shared link.

so far, they didn't support batch download, so if those link has a lot files, u should download one by one.

click download icon on same row, fill the captcha, then it will show download link. recommended way is use 2nd row (aria2) with xdown. you can download xdown here
