I used a bootable Linux mint usb and opened a sensitive txt file and added sensitive information to it. This txt file is encrypted by Veracrypt and was only opened and edited while I was offline.

After editing I dismounted the Veracrypt volume. This was using the default text editor in Linux. Is there any place a temporary copy of the unencrypted file could be saved on my device?

I want to nuke any possibility of the unencrypted files presence on the device.
