Reopening Files

If you open a file on a floppy disk, you should close it before your application relinquishes control to another application. The most convenient time is immediately after reading or writing the file. The file can always be reopened using OpenFile with the OF_REOPEN option:

hFile = OpenFile((LPSTR) NULL, &OfStruct, OF_REOPEN | OF_READ);

In this example, OpenFile uses the filename in the OfStruct structure to open the file.
