Is there a size limit for uploading files to DropBox?
There is a limit of 150 MB for files uploaded to DropBox via iTalk. This works out to about 34 minutes at the Best recording quality setting, 68 minutes on the Better setting, and 136 minutes on the Good quality setting.
If you have a larger recording that you need to transfer, we recommend transferring those files to your computer using iTunes. You can find more information on iTunes File Sharing HERE.
