Where is PHP on QNAP?
Well.. at least on my QNAP TS-210 it is in:
/mnt/ext/opt/apache/bin/
You can validate this by executing:
/mnt/ext/opt/apache/bin/php --version
Which should show version PHP installed on your QNAP box.
Symbolic links under Windows 7…
...are possible! All you need to do is to use mklink program:
mklink /d "D:\Photos" "\\SERVER\Photos\Family\Dad"
