File Storage Emulated 0 [NEW] Download Facebook.mhtml

Note: At least in my phone, /storage/emulated/0 does not correspond to SD card, but to intern memory. This method did not work for my external card, but I never tried it with another phone.
Plug in your device and run adb shell which will get you a command shell on your device. You don't have permission to read /storage/emulated/ but since you know it's in subdirectory 0 just go cd /storage/emulated/0 and you will be able to look around and interact as aspected.
So, the /storage/emulated/0/DCIM/Camera is the same folder as your normal DCIM/Camera folder. Its just a symlink. So the files are actually in the right location you just have an app that put bad data into the MediaStore Database.
When accessing files from your PC your are actually enumerating the MediaStorage database for files. Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Files in the database pointing to emulated directories aren't shown as they are assumed to be duplicates as its the same physical directory as your normal DCIM/Camera. What is going on is that some poorly written third party apps are inserting entries into the database with the /storage/emulated/0/DCIM/Camera path instead of the proper root path to DCIM/Camera. Which means that the MTP service can't see them when you are hooked up to your PC.
Android recommends that you call Environment.getExternalStorageDirectory.getPath() instead of hardcoding /sdcard/ in path name. This returns the primary shared/external storage directory. So, if storage is emulated, this will return /storage/emulated/0. If you explore the device storage with a file explorer, the said directory will be /mnt/sdcard (confirmed on Xperia Z2 running Android 6).
In my case, /storage/emulated/0/ corresponds to my device's root path. For example, when i take a photo with my phone's default camera application, the images are saved automatically /store/emulated/0/DCIM/Camera/mypicname.jpeg
To RESTORE your pictures from /storage/emulated/0/ simply open the 100Andro file..there you will see your pictures although you may not have access to them in you pc explorer. There open each picture one by one, go on setting (three dots..) and save the picture. It will show up in the android file 'Pictures' from where you can also copy them by using your explorer. There is no 'save all' function, however so it must be done one by one, but it works.
I have a vast number of webpages saved using an earlier Brave version on Android. Is there a quicker way of exporting them than to individually convert to pdf? I just want to move them to external storage to free up gigabytes of precious internal storage on my Galaxy A6 tablet.
Actual webpages. The Brave version I was using is about 2 years old and, unlike the current version, saved webpage downloads internally. They became part of the storage space used by the Brave app, not seperate files stored outside the app. The only way I know to shift them is to convert each one individually to a pdf. Very time consuming, not all that reliable with the old version of Brave, and very unreliable with the latest version.
Recently, I've figured out that if I delete files from /sdcard/Download it deletes files from /storage/emulated/0/Download. And if I add the files into /sdcard/Download it duplicates them in /storage/emulated/0/Download.
* >S> for symlink, >E> for emulated and >B> for bind mount
* USER-ID of current user in case of Multiple Users or Work Profile, normally 0 i.e. that of device owner
* VIEW is one of read (for apps with permission.READ_EXTERNAL_STORAGE) or write (permission.WRITE_EXTERNAL_STORAGE) or default (for processes running in root/global mount namespace i.e. outside zygote)
* There were minor differences on previous Android versions but the concept of emulation was same ever since implemented.
* For a little bit more details on Android's mount namespace implementation, see this answer.
In short, /sdcard and /storage/emulated/0 - which represent a FAT/vFAT/FAT32 filesystem - point towards /data/media/0 (or /mnt/expand/[UUID]/media/0 in case of Adoptable Storage) through FUSE or sdcardfs emulation.
Early Android devices were short on internal storage and relied on (physically) external SD cards that traditionally use FAT family of filesystem to ensure compatibility with most of the PCs (refer to Microsoft's dominance on PC world).
When the internal storage grew in size, same filesystem was shifted to internal (still called "external") SD card.
But the FAT/vFAT implementation had two major issues which were addressed by Google gradually:
Now the apps (and MTP, which is also an app) interact with emulated storage instead of /data/media, achieving both purposes at the same time i.e. enforcing permission checks underneath and looking like FAT filesystem on upper surface.
