File Flush [SOLVED]

5 posts in this topic




Revolter,

This is the hobbyist's answer - I hope it suffices! :(

Windows does not always write an amended file directly to disk - it may well be reading another file for the moment and so the disk heads are in use. So it puts the amended file contents into a buffer to write later when it has more time and the disk heads are free. Closing a file will force the buffer contents to be "flushed" - that is written to the disk immediately.

If you are doing lots of very large file writes and reads, you may find that the file you thought you had amended has not yet had the changes written to it as Windows was too busy. Using FileFlush will force the file to be written to disk - or "flushed" from the buffer.

I have only come across this very rarely (the last time was a few months ago when I was trying to use an ini file for interscript communication) - the faster CPUs and disks used nowadays tend not to have this problem.

All clear? :graduated:
