With FoxBarcodeQR not need to copy and delete the image file generated.

In the Image control's Label, you must call the method QRBarcodeImage() as shown in the image in http://i3.codeplex.com/download?ProjectName=VFPX&DownloadId=625345 or the attachment file.

In this way, each image file has a unique name generated and saved in a folder in the Windows temporary files, automatically eliminating in the Destroy event of the QRBarcode class.
