I've read the thread. On freemyband, it says the file should be in "/sdcard/freemyband folder of your band ". Is there a folder on the band I should be able to read?
I don't have a "Mi Fit" folder or "Information.txt" file on my phone.
Using Amaze file explorer, it starts at /storage/emulated/0. I've searched that tree and I've gone up the tree, no files like those you mention. I tried showing hidden files, that didn't help either.
