This updated FAQ covers all the ways to locate and manage data. Double-check and if you are still having problems, write back.
https://galaxyproject.org/support/ >> The account usage quota seems incorrect
Should you still have problems after that review, where you are working will probably matter for more help.
Your email address at this forum is not the same as at usegalaxy.org. Is that really where you are working?
If yes working at usegalaxy.org, post back confirming then I’ll send you a direct message where you can share your registered account email privately, and I’ll try resetting the quota administratively. You should not share your password: no administrator will ever need OR ask for it. Note: there are no known problems with this function, so there is almost certainly un-purged data in your account. But we can follow up. The server did just go through some updates.
If not, please clarify – the public server URL or some other configuration (local, docker, cloud: explain details such as where sourced and what version of Galaxy).
