What happens to data when you cancel a download on firefox?

I was downloading a kinda big file and decided to cancel it. I'm curious about what happens to the data when you cancel it. If is still somewhere on the pc is there a to delete it? I have enough junk on the pc as it is.What happens to data when you cancel a download on firefox?
Usually when you the user cancels a download, the file that is in the process of being written will not be saved. Whatever was in the cache and not saved to disk will eventually be written over so that it ceases to exist. Whatever was physically written to the hard drive will still be on the hard drive as ones and zeros, but it will not be a file that you can see or need to delete. Eventually another file that you download will be written over the data and it will cease to exist. As data that is written but not recorded as a file, it is possible for the FBI or the CIA to recover information from it, but you as the end user do not have that capability. You would need to start to download the file over again as if from scratch.
Now there are download managers that are designed to resume an interrupted download. They finish writing the file as a temporary file, so that its data will not be written over by new downloads.
When you choose to resume the download, the program appends the new information to the end of the existing download until the whole thing is complete.
Using a program like Bittorrent, you will have the option to allocate space on the disk for the entire file prior to the completion of the download. This allows you to ensure that you will not run out of space before the download is completed. It also allows the file to be written in as contiguous a block as possible rather than being fragmented all across the hard drive. This may not be applicable to file systems other than FAT, aka File Allocation Table. I am only somewhat knowledgeable with this older file system.

Generally, when you start to write a file but do not finish it, it will cease to exist as a file and any space it started to take up will be recycled the next time anything is written to the harddrive. If Firefox saves a user canceled download as a temporary file that you have to manually delete, I would consider that a bug. Even before the internet in the days of Bulletin Board Systems that used dial up modems, there was a download protocol called Zmodem that allowed interrupted downloads to continue where they left off. By interrupted, I mean a temporary outage of connectivity, not a user cancellation.
In windows, when you delete a file, it gets placed in the recycle bin to give you a chance to change your mind and recover it before the space it uses is recycled. Its physical bits on the hard drive do not move, but only the logical location of it moves. However if you never finish writing a file in the first place, it does not go to the recycle bin, but simply does not get recorded to the file allocation table in the first place. Logically it never existed.
Of course some programs may have a default option of saving a canceled download as a temporary file. So to free up space on your hard drive, you will want to tell your browser to delete all temporary files. You will also want to "empty the recycle bin" in windows.What happens to data when you cancel a download on firefox?
it can be continued to be downloaded, but trying to reconnect is hard time, and your downloaded maybe cant be resumed, because of timeout. This is mainly caused that server refuse to continue or it doesnt support resume download. Try more reliable download manager such as idm. It is very reliable and fast, and can use up to 16 connections in a timeWhat happens to data when you cancel a download on firefox?
For example, you downloaded half way, and then you canceled it. Half of that file would still be somewhere in your computer (usually in the download folder), but it is unusable and will take up unnecessary memory space. Do delete if you happen to find it :)

it becomes corrupt and unusable.
it should be in the "Downloads" folder.
