VFP8

I have an application that takes a file and store it in a table the patern is really simple and it's working great. But my application is not releasing it's memory it can grow up to 500 megabytes of ram.

I only use local variable an I call my table my patern is

INSERT INTO BackUp (mFilename, mFile) VALUES (FULLPATH(laDir(i,1)), FILETOSTR(laDir(i,1)

(laDir is populated with ADIR())

anyhelp will be appreciated
