Is it posible to get the used and free storage in Dropbox, Box, Google Drive, etc.
I have been searching the code but it seems there is not a function for that. I found a 'Storage.Drive.Capacity' property but I don't know what it is for.
This information is currently only available for DropBox.
You can perform a call to GetAccountInfo which will fill the Info properties.
The Info.Quota property contains the total amount of available storage and the Info.QuotaNormal property contains the amount of free storage.
Similar functionality for Google Drive and OneDrive will be included with the next release of the TMS Cloud Pack.
Unfortunately this data is currently not available in the Box API.
