I cut and paste an 80GB worth of files and folders. At about 80% I cancelled it. Are some of the files deleted and gone forever? Does the files that were successfully transferred gets deleted? If yes, can I still recover them?
When you cut and paste the data, the data transfer proceed one by one file from the location to transfer the another location. The files until not complete transferred to another location the file doesn't delete from the original location(from wheres you cut it). If by chance the transfer interrupted the files which has not transferred yet will remain on there original location and you can again proceed your transfer.
There is a very small chance of data loss if the transfer is interrupted due to power failure or a system hang. In my case I never lost data when I cut and paste it from one location to another and never mind what the size it has.
No file should be lost. Information that was copied will remain copied, and information that was not copied will remain where it was.
