    1. COI assume these are the maximum number of files for the entire partition, not a directory. Thus, this information isn't too useful regarding the problem, because there'd be an equal number of files regardless of the method (unless you count directories as files).

    2. COSince we're in 2012 now, I think its time to make clear that ext4 doesn't have any limit concerning the number of subdirectories. Also maximum filesize grew to 16 TB. Furthermore, the overall size of the filesystem may be up to 1 EB = 1,048,576 TB.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
