Ext3 will not complete the activity that was happening when the power was interrupted. It tries to bring the system back to a last known state, but you may have corrupted files after (such as a file that you were transferring). It does help in that it does not have to go through the fsck check after an unclean shutdown (have you ever had to fsck an 80 GB disk??). Moving a file does not remove the source file until it has completed, thus in your example, the destination file would not be finished, but the source would be fully intact. You could probably use rsync to continue moving the file, so that you wouldn't have to start over, but I'm not sure how much of an issue that is.
