There are a few factors that determine upload time.
What is the file size? What is your internet connection speed? Are you running multiple browsers or programs that draw bandwidth?
We recommend that you close all other browsers while uploading files to newrow_.
If you are still unable to upload a file, make sure that the file you are uploading is not corrupt. Try uploading another file to check if this is unique to this particular file.
If the problem remains and is universal to every file, please make sure you are connected to a high speed internet connection. If you are on wireless, opt to plug in directly through Ethernet and disable the WiFi.
