Vivaldi standalone - large Installer folder

[lemonjuice]

I'm using Vivaldi standalone installation on my external USB drive and I've noticed there is a folder Application\2.2.1388.37\Installer which takes up 240 MB, which is roughly half of the whole Application folder, which is 463 MB altogether. The Installer folder has 2 files: setup.exe and vivaldi.7z - this .7z file is the large one.

Now I'm wondering why is the Installer folder there and can I get rid of it safely? I think it's only used for self updates and it wastes my drive space by being there. Even then - why does the installer not get deleted after an update or first installation? The whole application could consume 50% of its current size on disk and the current set-up seems very sub optimal to me.

It's there to allow the differential update to be applied, which reduces the download time of each update. If it doesn't matter to you to download the full installer each time, you can safely delete the installer\ dir after each update.

Old installations are removed after a new update, that will remove the old installer.

But the installer is not removed. I've check another standalone installation I have and after a few updates the Installer folder is still there.

I see. But this looks like a weird solution because when I open the installer (vivaldi.7z) it appears to contain the same files which are in the main Application folder - then why can't Vivaldi use the Application files for differential updates? Even if a separate set of installer files were needed it would be much more efficient to store only hashes of files instead of whole files. This whole procedure seems to not be optimized well but I suppose the programmers didn't find it important to make it space efficient.

Anyway, thanks for explaining. At least I know I can safely delete the Installer folder or exclude it from backups.

Removed is mis-leading, the contents are replaced by the updated "installer" files - thus the "old" ones are removed but new ones are added to facilitate the next update.
