Im trying to use OLE linking to provide a preview of .bmp images for a simple database application written in VFP6.

I have an OLE bound control on a form whose control source points to a general field in my database table. I create the link using the the following command.

APPEND GENERAL drwindex.olefield FROM (FileToLinkTo) LINK

No problems with doing this everything works fine.

My problem is that the FPT file associated with the database table gets very large. For example before I establish any links the FPT file is 5KB. If you link one 470KB bitmap the size of the FPT file jumps to nearly 2MB.

It stays at this size even after you close the application, at first I wondered whether VFP was using it as some kind of temporary cache ?

If you keep on linking you rapidly end up with a FPT file of several hundred MB's.

I thought only the link was being stored ?
What am I doing wrong ?
