How to open 2 windows file / project explorer in netbeans?

Question

Is there a way to open 2 windows of files / projects in netbeans? I want one of these windows to point to one folder, and another window to point to another folder. When you have a lot of files, and you have to constantly switch between two folders, it becomes more and more unpleasant to scroll through them every time.

Answer 1

I did not find a way to open 2 project windows, but I put together a project and a window with a file in the same panel. Just open both windows and drag them halfway. You can also undock (swim) the windows and place them wherever you want.

Answer 2

There are no solutions. But you can “hack” like this: https://pandazen.wordpress.com/2009/12/23/open-netbeans-with-two-instances-windows-simultaneously/

Answer 3

The instructions given in opening-multiple-netbeans-ide-instances really work.

I tested it and worked as expected. You need to create a shortcut for towing different directories with the provision of the project directory.

Answer 4

Two open two instances of NetBeans, I double-click two program files in a row before NetBeans can start itself.

Answer 5

Let me explicitly add the “hack” mentioned by @Do_Nhu_Vy here (since I don’t trust third-party websites and I don’t have enough reputation to respond to his comments). All credit goes to the original WordPress user (Pandazen) at the specified link.

Now when

The hack / solution is to change the "userdir" of NetBeans at startup: when NetBeans detects a different "userdir" (than the already open Netbeans window), it then proceeds to open a new window.

The process of changing your NetBeans username at startup is simple:

1. Create an empty user directory, for example:

     C: \ tmp 

2. Duplicate an existing NetBeans shortcut (create a new one). Most likely, you will find a shortcut in the Windows Start directory

     C: \ ProgramData \ Microsoft \ Windows \ Start Menu \ Programs \ NetBeans " 

3. Right-click on the newly created Netbeans shortcut and select "Properties",
4. Change the "Target" field by adding the suffix --userdir DIRECTORY with the selected path, replacing DIRECTORY with the newly created empty directory. For instance:

     "C: \ Program Files \ NetBeans 8.2 \ bin \ netbeans64.exe" "--userdir C: \ tmp 

Now each shortcut will launch a NetBeans instance in a separate window. This works with NetBeans 8.2, but I have not tested it with NetBeans 9 or 10.
