This way can be slooow for big files, especially for floppies.

There is a direct way through DOS to get this info.

	FileLock=Lock(filename);
	Examine(FileLock,&FileInfoBlock);
	size=FileInfoBlock.Length; /* I think, check the includes */

The definitions you need are in
<libraries/dos.h> and <libraries/dosextens.h>

Info about Lock and Examine is in "AmigaDOS Developers Manual".

If you don't have this, I may be able to send the info to you tomorrow.
