I've always found this thing a bit confusing, but I'm never quite sure if it is doing something wrong or if I just don't get it.
Here, I think it is clearly doing something wrong.
On top I selected a file, and in the bottom the list of files looks like it may be correct.
Next, I scroll down to Monday and pick the first file - which would be the last file saved on monday.
Now, the bottom has just one entry.
Third, I select the last entry on Monday (the first file saved on Monday).
The bottom list now has lots of entries - and it is missing a file that I created and edited several times today (snowball). Otherwise, it is hard to say if it is correct or not.
It would be easier to determine correctness if the bottom list was shown in a different form, or forms.
#1: Include the modification timestamp for each of the entries
#2: Remove unnecessary folders:
It may show
1 *C:\foo\bar
2 [] file.txt
3 *C:\foo\bar\quick
4 *C:\foo\bar\quick\brown
5 *C:\foo\bar\quick\brown\fox
6 [] jumped.txt
There is no need to show lines 3 and 4 - they should be removed.
Better:
1 *C:\foo\bar
2 [] file.txt
5 *C:\foo\bar\quick\brown\fox
6 [] jumped.txt
Or, not include the full path in each folder
1 *C:\foo\bar
2 [] file.txt
3 *quick
4 *brown
5 *fox
6 [] jumped.txt
#3: As a sortable list with columns: Name, Path, Size, Time
#4: Same as #3, but show only the most recent modification for each file.
