On Mi Phones you may encounter issues when attempting to transfer files from the phone storage to SD CARD using ES File Explorer. I did not do an extensive research but I confirm that this issues did not occur on MiUi version less than 7.5. If this problem exists, then we can't create new files and folders using the ES File Explorer options on the SD Card.
While attempting to create, copy-paste or move files, we normally get a prompt to allow permission to ES File Explorer to access SDCARD Root.
The prompt says:
Please choose the root directory sdcard1 of Ext-SD Card to grant ES Permission to operateAnyways, whatever the version, if you are facing issues transferring or copying files to SD CARD specifically when using ES File Explorer, then resolve it by following the steps explained in thevideo below.
After enabling "documents" under installed apps in Settings, and enabling access to the root directory of the SD Card in ES File Explorer as described in the video, you should be able to transfer or move files to the SD Card.
- This solution is particular to Mi Phone and ES File Explorer. I am not sure if ES File Explorer throws this error on other phones. MiUi version as on the date of making this video is 7.5 (Stable).
- You might need to do the same process if your have inserted another SD Card or while attempting to transfer files to pen drives plugged in to the phone via OTG.
