Volume numbers , and new folder


My Book\WD_Smartware\ there’s 6 alpha-numeric folders. I assume for the various backups.

Today I ran a backup, and it appears that another folder was created on the My Book

My Book\WD smartware.swstor\desktop\ another long alpha-numeric

Do the different locations mean anything different ?

Also, are you able to identify the date ran from those alpha-numerics ?
