Hi @tanzilhuda,
Please be informed that at present there are no features in KoBoToolbox where you could find-out the storage space used within your KoBboToolbox User Account. However, you could do this manually as follows:
- Download your xls dataset and check its size
- Download your xlsform and check its size
- Download the csv, media and other attached files and check its size
- Finally calculate the size of all the files (and projects) that are in your account
FYI, you could also have a look at the discussion that has happened in the past. Maybe you could vote for it if you wish to see this feature in the upcoming days.
HAVE a GREAT DAY!
