I think I can provide an explanation and a solution for this problem. I am not (yet) an Eclipse user, but from carefully reading the evidence presented, the problem and solution are perfectly clean.
The problem is that Eclipse want to CREATE a NEW folder. This is clear because one of the steps described is "Create New Folder." If there is no other function than this to do what we really want, then we simple use this function. No problem. The solution is to start by renaming your folder containing your utility classes. In cases like this I like to add an underscore character as the first character in the name. This should cause the folder to be listed as the first entry in the list. Now go through the steps to get back to the browse dialogue. Select the folder that you renamed so it appears in the input box. Now edit the entry to remove the leading underscore character from the name and click OK. Eclipse should now create a new folder with the name you want. With this done, you can move all the files into the new folder and delete the original folder. No problem.

Into this package I copy a class HelloInt. package main; public class HelloInt { public static void main(String[] args) { System.out.println(IntegerFormatter.format(334928,14)); } } My Eclipse directory is C:\B\E\ Elsewhere I have a directory C:\temp\utility which contains IntegerFormatter.java, a utility which I want to use. In Navigator, I right click on project tryUtility. Then Properties > Libraries > Add Class Folder > Create New Folder > Advanced > Link to folder in file system > Browse ... I select C:\temp\utility, and back in the New Folder dialog type "bob" in the Folder name text field. I click OK, then OK again. Then, back in the "Properties for tryUtility" dialog, the OK button is disabled. An error message near the top of that dialog says "Cannot nest 'tryUtility/bob' inside 'tryUtility'. To enable the nesting exclude 'bob/' from 'tryUtility'." For your enjoyment I'll try to attach a gif of that dialog window. I am having fun, and hope you can have fun too.
