<p>How do I copy a directory including sub directories excluding files or directories that match a certain regex on a Windows system?</p>

I don't know how to do an exclusion with a copy, but you could work something up along the lines of:
```
```
ls -R1 | grep -v <regex to exclude> | awk '{printf("cp %s /destination/path",$1)}' | /bin/sh
```
```
