Do you mean limited storage space? The upload limit stays the same between the paid or unpaid versions, usually the app has no file size limit but the web version does. For instance, the web version for DropBox limits the size of the file to be uploaded to 10GB or less, regardless of how much storage space you have or whether paid or free.Just remember, with these cloud based storage and especially the free versions, that there is a size limit to the upload. Where as the paid version have a decent upload size limit. The only one I've found to work pretty good is G-drive from Google.
