            Bug ID: 49539
           Summary: IShellView displays incorrect file size for files >2GB
           Product: Wine
           Version: 5.12
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: shell32
          Assignee: wine-bugs(a)winehq.org

explorer screenshot

The IShellView directory listing (i.e. in explorer.exe) shows an incorrect file
size for files larger than 2 GB. Right click->Properties shows the correct file
size. See screenshot.

I think this is caused by the use of a DWORD for dwFileSize in the PIDLDATA
FileStruct, and used by _ILGetFileSize.

Yes, I think it's mostly GetDetailsOf() fault. We still use _ILGetFileSize()
for sorting in shellview, but that's likely wrong in general.

On Windows it will be same overflow in PIDL item field, while GetDetailsOf()
returns correct string still. Another difference is that Explorer string does
not match what GetDetailsOf() returns, on Windows Explorer returns size in KB,
and GetDetailsOf() will show GBs.
