Bug ID: 58437
           Summary: Total Commander 11.55 complains "Access denied" for
                    EVERY file >= 1 MB in "Compare files by content"
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org

screenshot displaying the error message
When I call in TC (Total Commander) Menu "Files / Compare By Content" and one
(or both) files have a size of 1 MB or greater (exactly 1.048.576 bytes or
anything greater) then TC shows an Error Message "Access denied on file XYZ"
(see attached screenshot) and the compare aborts. 
But EXACTLY the same file(s) can be displayed (by F3 = Lister) and edited (by
F4 = Editor) WITHOUT any problems! So this file has NO general problems, but
only always with Menu "Files / Compare By Content".
More infos:
 - this bug occurs identically with ALL tested 32-bit versions of TC = 11.55 +
11.51 + 10.51 + 10.50 + 9.51 + 8.52
 - this bug does NOT occur with all tested 64-bit versions of TC = 11.51 +
10.52 (but in all 64-bit versions of TC it's GUI is displayed not correctly,
which makes using them confusing and uncomfortable, so 64-bit is no good
workaround)
 - it did not help to create a new 32 bit wineprefix via "WINEARCH=win32
WINEPREFIX=/home/hg6/.wine32 winecfg"
 - this bug occurs with wine-10.0 and wine-9.0 (Ubuntu 9.0~repack-4build3),
both on Ubuntu 24.04 x86_64
 - this bug only occurs with all files >= 1 MB on NTFS + FAT32 + FAT16 file
systems, but not on an ext4 file system
 - this bug did NOT occur with wine-6.0.3 (on Ubuntu 22.04 x86_64 with exactly
the same files and exactly the same TC versions)
 - of course this bug does not occur on pure Windows (with exactly the same
files and exactly the same TC versions)
 - chkdsk (in pure Windows) did not find any errors on the affected drives
