How do I keep IntelliJ from closing my Editor Tabs automatically?

Question

When opening more than 10 Editor Tabs, IntelliJ automatically closes my least used Tab each time I open a new Tab.

How can I increase this limit?

More recent IntelliJ settings are accessed differently than older versions.

I was wondering, WHEN and why i closed some files. IntelliJ was closing stuff without asking. Stupid features sold as smart ones... – Mardis

Answer 1

Change the Tab Limit under the Tab Closing Policy settings.

Open your IntelliJ settings: Select File -> Settings -> Editor -> General -> Editor Tabs.

Look for Tab Closing Policy -> Tab Limit and change the value to a higher integer.

You can also select to either close non-modified files first or less frequently used files first once your tab limit has been reached.

in Mac os, it's under Preferences -> Editor – Limpopo

Same will be applied to Android Studio for Mac, in version 3.3.1, select Preferences >Editor >Editor Tabs > Closing Policy section > Tab limit. – Sufism

Answer 2

If you need more than 100 tabs:

By default, the maximum number of open tabs that you can allow is limited to 100. If you want to increase that limit, press Ctrl+Shift+A or choose Help | Find Action from the main menu. In the popup that opens, start typing Registry, select the corresponding item and press Enter. In the Registry dialog, search for the ide.max.editor.tabs key and change its value.

Adding an answer to help anyone else with a similar problem. OSX+Catalina on JetBrains/PyCharm was having closing all tabs when I lost focus on the application. When I came back the "Synchronization" action happened (top right circle arrow spins) and all windows are reset (many closed as a result). My fix was to disable in the settings. Appearance & Behavior > System Settings > Disable everything under the "Synchronization" section. You may need to seek out other "sync" options in settings.
