Electron Package Version:

5.0.6 for 32-bit Windows

Operating System:

Windows 10

Last Known Electron Package Version Without This Folder:

4.2.5

After updating Electron from v4 to v5 I found a new ~9MB folder inspector containing 188 files in the Electron package install path at node_modules/electron/dist/resources/inspector or ${packagedApp}/resources/inspector after packaging with electron-builder. What is this for?

There seems to be no consequences for deleting this folder. I can still use Electron and chrome devtools perfectly fine after removing it.

Can it be safely deleted/excluded from my packaged app?

Any help is appreciated!
