1. /SDcard LOST.DIR/32411. It is about 293MB.
2. Internal storage/Whatsapp/database/msg store.db.crypt12.
There are about 9 files of each above 100MB under this category. They are dated from 26-09-2020 to 4-10-200 i.e. since last week.
3. Another set of nine files similar as above, and which are each more than 25 MB are dated 13-09-2019 t0 20-09-2019.
I am not able to read the contents as it says "none of the apps in your phone can open this type of file".
Similarly in Whatsapp audio files there may files with extension named '.opus.' There also it says that 'you don't have any apps that can open thus type of file'.
What are these files? Can I delete these files safely to save space? Will that cause any issue in my phone or will I lose contents?. I need to create more storage space.
