4610	filesystem::file_size problem on Windows platform	neo_in_matrix@…	Beman Dawes	"This is a subtle problem on Windows platform.

I see that file_size calls GetFileAttributesEx to obtain file size - that works in a chance of 99.99%.

What is the other 0.01%? It's like this - GetFileAttributes(Ex) does not work with system files, say c:\pagefile.sys. It will only return FALSE and GetLastError returns 32 (The process cannot access the file because it is being used by another process. )

Instead, you have to call FindFirstFile which correctly reports file status in all cases."	Bugs	closed	To Be Determined	filesystem	Boost 1.44.0	Problem	wontfix
