Thanks for your replay
No, I don't have it.
Today I did the backup of some content and downloaded on moodledata/temp/backup.
Now my moodle size is 187Gb
later I deleted all files from moodledata/temp/backup. which I have downloaded today.
later I ran the cron.
now my file size is 174GB.
how it possible what action I did is download backup file (.mbz) and deleted what I have downloaded so it should have 167GB
but it showing 174GB
and I'm not able to see my old content in moodledata folder but the size is still 174GB
please see the attachment file
