Hi,

>Wether is it possible within Visual Foxpro commands or I should use any Third Party tool.

If you only need to access the folder with VFP, you can use cryptor to encrypt all files in a folder. There also used to be a program called compaXion that provided a virtual directory which is completely stored in a single file. Both are products of XiTech (http://www.xitech-europe.co.uk/).
