[SOLVED] Just updated to IDEA 2016.3 using JetBrains Toolbox. Can I delete the old IDEA folder? Follow
It seems that when the user updates his JetBrains IDE via Toolbox the tool doesn't really clean up after itself. My ".IntelliJIdea2016.2" and "C:\Users\<user>\AppData\Local\JetBrains\Toolbox\apps\IDEA-U\ch-0\162.2228.15" weren't deleted after I launched the new IDEA and told it to import data from 2016.2. Can I simple go there and delete those folders? Will it cause any issue?

It does. However, Toolbox has a feature called "rollback" – if for some reason you don't like the update (something wrong after update with your project, or there is a regression bug on our side) you can immediately roll the previous version back. That's why Toolbox saves one extra copy.
@Konstantin Bulenkov thanks for the fast reply, so if that's the case I have two questions:
1. Yes. It will happen even if you update to say 2016.3.1. So, you will have 2016.3.1 and 2016.3 as a backup version
2. Try to do it. I don't see any problem here. And you're welcome to vote here https://youtrack.jetbrains.com/issue/ALL-657
@Konstantin Bulenkov Again, many thanks for the clarification. I voted there.
The problem on Windows 7 is that I do not seem to be able to delete the old \Users\xxx\.IntellijIdeaYYYY.N folders. I have 5 of them now, including the current version (2017.3). I've even tried opening a file explorer as administrator and I *STILL* cannot delete them. The extra junk is getting sizable...
I just figured out a way to do it on Windows 7:
Still Not Clear. If I delete the older versions' folders, Will it create any problem?
No problems, I delete all versions after every update.
