I've uploaded some files to my project (/storage/groups/a/an/anarchy/testing/hello-world.txt and .../testing/test.txt), but now I don't know how to delete those two files.
Is there a way to delete those files using the web interface or through the terminal?
Unfortunally, we currently provide no way to manage storage files via web interface.
You can delete the files by follwing way;
Run rsync again with --del option after deteting the files from local directory. (You can use --dry-run option to check which files will be deleted before actual run)
Connect file storage area with sftp to remove any files interactively.
