Hello Rick Strahl :
yesterday I studied the document titled "DEVELOPING VFP APPLICATION FOR WINDOWS VISTA", write by Doung Henning.
thanks to Tore Bleke give me the refer link of this document. now I undestand how to work with this new characteristic of Windows with VFP.

however Iam getting errors and lost data with many type of software instaled on Win7 PC machine. one case of error is:

when I copy a sql-ce database located in a Modern Industral HandHeld (with WINDOWS CE 6.0 R3) to a PC-WIN7 some times the data is copy to real ubication, some time the data is copy to virtual store and some time the data is lost.

Iam tested the handheld software comunications with other machines with other OS and I resume that the ramdon error is caused by Virtual Store function.The communications software named lmwin was developed by CASIO Industrial Japan.

then I need disabled Virtual store to write files on real ubications without virtualize directory files store.

Thank again
