Opened/closed projects in one workspace - how many is too many?

Having lots of open projects will slow down startup, refresh, and all the background tasks that rummage through source files looking for problems. Usability depends on whether you need all those projects open - whether it gets hard to find what you're after - nothing to provide a solid answer about.

Usability depends on whether you need all those projects open - whether it gets hard to find what you're after - nothing to provide a solid answer about. Closing projects brings them down to virtually no cost at all.

Working sets don't benefit performance directly. They obviously will help when you reduce the scope of operations, like searching, by using them.

Closing projects you're not working on, also has the usability benefit of a better overview in the package Explorer. Closed projects are automatically collapsed by Eclipse and the Icon (blue closed Folder) also has less Subicons like warnings, the little Maven "M" etc. That makes it less distracting by scanning over your projects and looking for the relevant ones.To close projects you're not currently working on is definitely a good idea. (Mainly because of the issues Ed mentioned in his answer) If you definitely won't be needing the project anymore, you may as well remove it from your workspace.

Gives you an even better overview ;-).

Good point, but for usability, I would prefer working sets. Or maybe, you know a way of filtering workspace to opened projects only, not to exact working set? – Adam Jurczyk Nov 18 at 13:10 1 @Adam: Yes, you can do that.

Go to the Filters in the package Explorer, and check the entry "Closed projects" in the field "Select the elements to exclude from the view" – Karin Nov 18 at 13:42 Ok, thanks for tip:) – Adam Jurczyk Nov 18 at 17:07.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
