I have Pogoplug connected to my SME account and I use SmartFTP to upload my files. On one computer, I can stop and resume an upload of an sqlitedb file and the upload continues from where it stopped. On another computer, when I stop and resume an upload of an avi file, the file gets uploaded from the start. Is this problem with SME or SmartFTP or Pogoplug? And how to enable such option?
