Error reading file: No space left on device
I had a large SQLite file C:\Users\D-Ef\AppData\Local\TradeClient\realtime.db that I was unable to copy to another disk. I tried:
split -n 10 -d -u realtime.db /mnt/d/db/rt
dd bs=65536 if=realtime.db of=/mnt/d/db/rt
in WSL, but got ‘error reading ‘realtime.db’: No space left on device’ with all the commands.
Finally I reduced page file size restarted my machine and copied the file in a usual way.
