I have a backup process from my phone that seems to be working well, but I'm confused about why this is happening:
- I move files on my phone (android 7.0.1) to my external storage (micro sd card 64GB) [free space was 1.4GB]
- turn off phone, remove sd card, put into USB sd card reader, plug USB into computer
- Open explorer windows (2: one for the sd card, one for the destination dir)
- Move/Delete files
- Confirm in Windows Explorer that free space is created [~7GB used of 64GB], files are gone from SD and spot-check that they are readable in backup location
- eject drive safely, remove USB reader, remove card from reader, insert card into phone, turn phone on
- Check external sd card using Total Commander on my Android, see the "moved" files still there, readable, reporting at full size, while free space is also still there [Total Commander Android reporting ~7GB used].
I'm not doing any kind of secure delete, so I'm not overwriting the files with zeroes or anything like that...
I assume that Windows is deleting the headers and leaving the files intact, but Total Commander should not see these files, right?
What is happening here? Why can I still see the files on the SD Card using TotalCommander on Android, but not on Windows?
NOTE: the sd card is definitely NOT write protected.
