Question

How to add more indentation in a file tree structure? It has a little bit indentation I want to increase more just like NetBeans.

Answer 1

Go to File > Preference > Settings and choose:

Workbench › Tree: Indent

Controls tree indentation in pixels.

or (in your settings.json enter this directly)

 "workbench.tree.indent": 10

and choose a high enough number for you.

Also see my answer at Visual Studio code sidebar Vertical guideline (customize sidebar) where with v1.36 you can add colorized tree indent guides to make the explorer file structure more obvious.

The example picture uses: "tree.indentGuidesStroke": "#00ff00" in the colorCustomizations, so the guidelines will appear green.

{                                         // in settings.json
  "workbench.colorCustomizations": {
    "tree.indentGuidesStroke": "#00ff00"
}

In a small change coming to v1.64 note that the minimum tree indent will be raised to 4 from 0 previously. So you will not be able to go less than 4.

Answer 2

If you just want to change the indentation you can set these options:
Press Ctrl+Shift+P -> Go to Preferences: Open Settings (JSON)

"workbench.tree.indent": 18,

You can add guidelines as well with:

"workbench.tree.renderIndentGuides": "always",

You can also change their color using:

"workbench.colorCustomizations": {
    "tree.indentGuidesStroke": "#008070"
},
