>Has anyone already written anything which copies a directory structure but only copies those files that have changed? I have a utility that does that, but I want to do something specific to VFP files. For example, if the file is part of a form and either the .sct or .scx have changed, I want to copy both the .sct and .scx. The same for reports and classes, et al.

Tracy,

I think robocopy will do the job. It can keep a mirror copy of a folder + subfolders. Copies new/changed files and deletes files that have disappeared.

I think its included from win 2003 onwards and it was included in my Vista. I use it every day to sync my work to 3 usb drives. In addition, each usb drive as 7 folders (01 02 03 ... 07). On monday I sync my D: drive to V:\01, Tuesday to V:\02, etc. So I can always go back a week
