The issue can be divided into two parts :-

Hey @lindapaiste , @raclim can you assign this issue to me as I am already working on this.

Expected Behavior

1. We should be able to delete the last file just like other files.
2. Also we should be able to delete the last folder without any problems.

Steps to reproduce

Steps:

For the first one try to delete all the files that are available.

For the second one create an folder and just some files into it, then delete all root folder files. Now if you delete the created folder the web app would crash.

Start by reproducing both deletion cases on Windows using the steps in the issue: delete all files, then delete the last folder after emptying its contents. No files or tests are named; done means the last file can be deleted and deleting the last folder does not crash the web app.
