TC7.50a: wrong sort order of "nameless" files

[yong]

There is something weird with TC 7.50a when it comes to display files whose names begin with a dot and have no other extensions: these "nameless" files are displayed in reversed order in the file panels like this:

• .txt
  .exe
  .c
  .b
  .ab
  .a
  .3
  .2
  .1
  .1.txt
  .2.txt
  .3.txt
  1
  2

However, pressing the hot key sequence Alt+Shift+Enter reverses the order of the "nameless" files but the other files have their orders unchanged:

• .1
  .2
  .3
  .a
  .ab
  .b
  .c
  .exe
  .txt
  .1.txt
  .2.txt
  .3.txt
  1
  2

This behaviour has been observed on Windows XP SP3 English version, locale Chinese (PRC), with the following TC settings:

SortUpper=0
sortorder=0
negative Sortorder=0

I can confirm the bug, even the peculiar thing of Alt+Shift+Enter reversing the order of the "nameless" files.

It is the same no matter whether I use sortupper=0 or sortupper=3.

But it is also a little more complicated than that. If I use a FAT partition (to store the file names in the created order) and then create the files in this (unsorted) order:
.exe
.c
.txt
.ab
.1
.2
1
.1.txt
.a
.3
2
.3.txt
.b
.2.txt

then sortorder=0 (name) puts them in this order:
.b
.3
.a
.2
.1
.ab
.txt
.c
.exe
.1.txt
.2.txt
.3.txt
1
2
where only the last 5 files are sorted correctly, and the first 9 files are showed in reverse of the creation order.

If I then press Alt+Shift+Enter this is shown:
.exe
.c
.txt
.ab
.1
.2
.a
.3
.b
.1.txt
.2.txt
.3.txt
1
2
where the first 9 files are now shown in the order they were created.


Windows Explorer sorts the files like this when sorting by name:
.1
.1.txt
.2
.2.txt
.3
.3.txt
.a
.ab
.b
.c
.exe
.txt
1
2
which is the same way that TC shows the list unsorted on a NTFS partition.

Thanks, this problem was caused by conversion to Unicode, and will be fixed in TC 7.51.

Confirmed fixed in TC 7.55b1
