Steps to Reproduce the Issue (STR)

1. Get a CMD prompt
2. Create a fairly lengthy directory path, e.g.

md w:\a123456789\b123456789\c123456789\d123456789\e123456789\f123456789\g123456789

3. Create TWO files in this path:

echo ImFromTest1>w:\a123456789\b123456789\c123456789\d123456789\e123456789\f123456789\g123456789\test1.txt
echo ImFromTest2>w:\a123456789\b123456789\c123456789\d123456789\e123456789\f123456789\g123456789\test2.txt

4. Open test1.txt into N++ by using File > Open and then specifying in the File name box:

w:\a123456789\b123456789\c123456789\d123456789\e123456789\f123456789\g123456789\test1.txt

5. Modify the file's tab content in some manner, so that its tab icons turn red.
6. Choose File > Close ; observe the appearance of this window :
   
7. Press the Cancel button so that test1.txt is not actually closed
8. Open test2.txt similarly to what was done for test1.txt in step 4, by specifying in the File name box:

w:\a123456789\b123456789\c123456789\d123456789\e123456789\f123456789\g123456789\test2.txt

9. Modify test2.txt's file's tab content in some manner, so that its tab icons turn red.
10. Choose File > Close All ; observe the appearance of this window :
    

Expected Behavior

I expected to see the full file path of my file when I'm prompted to save it in step 10, so I can be sure that I'm saving the intended file. I am shown the complete path in step 6; why not in step 10?

Actual Behavior

The file path of my file is truncated in step 10, so much so that I can't see the rightmost part of the path, leaving me uncertain I am saving changes to the correct file. The information should be presented more like in step 6.
