[Mingw-users] getting the size of large files under ntfs

[Earl K. <eh...@go...>]

In comparing various packages that provide an UNIX-like under Windows, I
found that the stat() function in the MINGW clib does not return the proper
file size for files over 4 gigabytes.  Presumably because it uses the same
library, the ls command of MSYS also does not report the proper file size
for files over 4 gigabytes.  (The size at which the failure takes place may
be less.  I simply happened to have a 4.8 gigabyte file that was reported
as approximately 500 megabytes.)  I have also found the same failing in the
Microsoft (Interix) Services for Unix and in the ATT Uwin package.  Since
the dir command in a "dos box" returns the proper file size, I presume
there is an underlying system call that does return the proper size for
large files.

I do video editing under Windows 2000.  For some applications, the work
file can be 60 or 70 gigabytes....

I did do a search through the archives using the key words stat and ntfs
without finding anything relevant to this problem.
