If im downloading a large file and accidentally cancel it at 90%, why do I have to “redownload” it all over again? Where did the 90% go

Your hard drive has an index which keeps track of where each file is saved. It has some computer sciencey name, but it’s basically an index of everything saved on the hard drive. In fact, you don’t need to save whole files in one piece. Your computer can save bits and pieces all over, and the index keeps track of where everything is. When you need to load the file back, your computer reads the index to find where the file is saved and then reads the data from those locations. When you delete a file. Your computer doesn’t actually erase the data from storage. It just marks in the index that those locations are unused. This is what happens when you cancel a download. Everything that had been downloaded is still there, but the record of where it was saved is gone. Without that, your computer can’t get the file back because it doesn’t know where to read the file from.
