Why is that? Is there any software related to Baidu installed? I was not able to find it in Settings -> Apps. Does it come with the original OS? I don’t think I installed anything related to baidu. How do I uninstall it?
I try google a little bit and I just found this:
But obviously I don’t have any xperia software installed, I don’t know if it could be something similar.
Not on my FP.
After googling a bit, it seems that most people having the baidu folder are sony xperia owners, and apparently it is related to the app ‘myxperia’ which, as I understand it, resembles Google’s Android Device Manager. So maybe enabling ADM could have something to do with it? There are also hints that ES File Explorer and Wechat are apps that connects to Baidu (which is a Chinese web service company not unlike Google), thus creating the folder.
You could, of course, uninstall ESFE, delete the baidu folder, reboot and see if it reappears. Or just live with it (don’t think therer are any particular reasons to suspect that it’s harmful).
Don’t think google apps is the reason - I have Gapps installed, just as @humorkritik (see his post above) and neither of us have the baidu folder. Have you installed aome other 3rd party app (presumably one that has to do with ‘the cloud’) that could cause it?
