I have a backups application that works across all versions of windows (Win 98 upwards).
In my application it is recommended to backup only data files eg: XLS, DOC, MDB, DBF, PST etc. (excluding application, OS system files ,temp files etc).
Can I safely Exclude the <Windows> and <Program Files> folders assuming they do not contain any user entered data ?
As my program unnecessarily searches in them.
