Hello,
today I needed to download a file over 3 GB in size from a customer's FTP server. I used DownloadStudio to perform this download task, and I found out that this product has serious problems.
The customer's FTP is on a slow link, and I started the download using four splits. Three timed out, and they DownloadStudio did not attempt to reconnect them, ever. There was still a fourth active connection, so the transfer should have been resumed.
After over six hours of transfer, when I finally had 97% downloaded, we had a power outage.

Well, no problem, I thought - I used DownloadStudio, so I can resume the transfer and just finish quickly, reight? Wrong! Apparently you did not plan for or test with files larger than 2GB, as the attempt to resume is resulting in a negative offset, as can be seen in the FTP log:

Six hours lost. No way to resume the download. Marvelous.
What is worse, there was not a single attempt to resume all four connections. It appears that DownloadStudio would continue to use a single transfer, after the power came back. Again, why?
I don't believe that I need to tell you how disappointed I am right now. This sucks so badly that I am ready to uninstall this product.
