OEM problem - Move file or Copy file?

[chinaox]

I successfully added several my MUST HAVE applications, and the files were correctly moved to install dir (such as Font or Program Files), but i still find the original copy under Windows folder, why was it there?

Another question, i see lots of HTC phones can delete individual call history, while latest Apache kitchen only supports Delete All History, I definitely just want to delete some of them. Any fixes?

Thanks.
