Backup/Copy changed/new data to CD/USB

I'm not an English native speaker. Please sympathize for my poor English

Please read my following situation:
- In "My Document" folder, there are 3 files: A; B; C
- My friend (John) needs all three files, so I copy them to USB (or burn them to CD) and send that USB/CD to him
- After a long time, things have been change: File A has changed to A1, new files appeared: D, E; just B, C haven't changed. So, "my document" folder has 5 files: A1; B; C; D; E
- John wants me to send him just changed and new data: A1; D; E via another USB/CD.

Although I tried a lot of backup software, none of them could solve my problem. They always require A; B; C to exist on USB/CD, then they compare the source and the destination to see what have been changed, and backup/copy changed/new data to USB/CD.

Could anyone suggest a program that helps me solve my problem ?
Thanks.

Sure... and easy to do with the SW built in to your OS (assuming Windows).  From a command prompt, enter

                XCOPY sourcedir\*.* destination\ /M /S


The /M flag says to only copy changed files, and turns off the archive bit so they won't be copied again unless changed

First, you may want to understand what "archive bit" (in SelfGovern's comment) is:
"Archive bit is one of the file attributes supported by file system. System will automatically set archive bit whenever you change this file or when you create new file. So meaning of this attribute can be considered as "file needs backup".

A small program may help you solve your problem, it is Synchronize It!

But the size is big and the speed is low.
