Is it still possible to restore deleted untracked files in git?

Some better IDEs keep track of your files as a local history. If you removed files externally (say, git reset) you should be able to click in your IDE on parent directory and choose "Compare with local history".

I used this feature successfully in PHPStorm IDE when my untracked files got wiped out by some utility...

In Intellij how to recover the untracked revert changes

Setp 2: Go to Local History, and then go to Show history

Step 3: Select the untracked files that your revert accidentally. then select those file in right side panel and revert the changes, you will get the files in reverted format.
