I used cobian backup 10 and used the "full" backup type to backup my personal folder on my C: hard drive to my external hard drive which amounted to 358GB of data.

Fash forward four months later and now I want to do incremental backing to back up the newly added files to the external hard drive. Why is it that whenever I use use this method a folder is created on the external hard drive? I thought the newly added files automatically goes to its appropriate sub folder of the personal folder in the external hard drive? This happens even if I use the same source( my personal folder in C: hard drive) and the destination of the backed up personal folder on the external hard drive.
