You're talking about one specific (and IMHO not very good) way of
creating a maildir hierarchy. Here's what I see on my system:-
chris@esprimo$ cd mail
/home/chris/mail
chris@esprimo$ ls -a
. .. Gm In Ju Li Tm folder
chris@esprimo$ ls -a folder
. apexLodge entertainment greville houseHome maxMum
reshapers tractor
.. archive family hardware internet money
riding travel
Scans boating france health isbd pcc
software ukraa
Shopping buySellAdmin friends holidays jrml personal
telecoms vehicles
chris@esprimo$ ls -a folder/Shopping
. cabin cycling garden maxine pets
stationery
.. car diy giftsEtc maxmum photography
telecoms
apexLodge clothesEtc electrical groupon medicine riding
toolstation
boat computer electronics houseHome motorcycle screwfix
books cpc food jrml music sportsEtc
No dot prefixes and my maildir hierarchy is a *real* directory hierarchy so
all the other file management utilities on my system can be used easily.
