Every game present on Steam is broken down into chunks of around 1MB in size. For each game bachelor, in that location is a manifest available which tells how to assemble these chunks into the game files.

When any update is released, Steam analyzes the update and calculates how it can make the files out of chunks that are already saved in its database. If it is something entirely new, it divides them into new chunks.

Now, when Steam gets to know that there is an update available for any of your games, it compares the new manifest against that which is already nowadays on your estimator. It calculates which files are modified and allocates space for them. It calculates which files it needs to download, copy over or replace.

What is happening if everything is in order and my download speed is notwithstanding low?

And so what does all this have to do with the low download speed? Well, let's suppose you lot have x large files. Their total size is a gigabyte each and in them, yous accept to alter 2MB of files. When Steam is edifice these files, information technology would take to download the 2MB files and copy the remaining 1022 MB from your existing installation per file. Multiply this by x (there are ten files in total). It would brand 20MB downloadable files and 10220 MB of copying. Therefore, you spend a lot of time waiting for these copies to happen; you are bound by the copying speed.
