As seen above, it’s been suddenly filled.
Furthermore, I tried downloading the whole workspace files and its size was only 30MB.
The only thing that I did except for editing the files is making Heroku master.
I’ve tried restarting the ide, restarting the bash etc. but it wouldn’t go back to the original disk space.
I’m assuming that it’s probably a display error because there is no problem in editing the files after this.
But I am a bit concerned that this might lead to some memory corruption/bug, so I thought that I should ask.
Closed, as it’s been fixed after some time.
