Steam – Can you download Steam Platform Updates without the Steam Client


Is it possible to download Steam platform updates using something that isn't the Steam client (i.e. HTTP) The steam client doesn't provide file size or time indications and I find this irritating when I launch a game and have to update.

Appolagies if this is a duplicate of something, I did search and didn't find anything.

Yes, Steam client updates can be downloaded manually via HTTP, if the names of the update files are known.

In my case, Steam seems to be unable to handle the poor Internet connection. When the network gets interrupted briefly, Steam just issues an error and exits; if I start it again, it can't resume the process and everything have to be downloaded again. So I'd like to use a robust download utility that supports pause and resume (i.e. HTTP Range Request).

The files it failed to download can be found in bootstrap_log.txt. (It is located under the directory ~/.local/share/Steam/logs on Linux). For example, this is one of the entries in the log:

Package file missing or incorrect size

To apply the updates manually:

  • Using your favourite download utility, download + package file name. In this case, it's

  • Put the files you've downloaded where Steam Client would. On Linux it is ~/.local/share/Steam/package/

  • Start Steam.

And now Steam should be extracting the updates right away, without downloading them again.
