Yes.

Ahh, I wasn't aware of these functions. I was trying to set them directly
and then writing the file.

This works except for SetFileDate. I even tried
struct DateStamp ds;
ds.ds_Days = 300; ds.ds_Hour = 0; ds.ds_Tick = 0;
SetFileDate(target_file, &ds);
But no matter what I do the written file has the current date and time. Any
ideas why this may be failing.
