What's the easiest way to Regex for any characters in the middle?

[nessaner]

Hello, I need to take events with two kind of text (different paths) :

Appended to:  G:\Streamserve\
Appended to:  D:\G_volume\Streamserve\

As you can see the is part in the middle that should be different (I have only those 2 kind of cases). I tried with \S* as non whitespace characters but it's not working.  
sth like this
Appended to: \w?:\\(G_volume)*\\*Streamserve

What's is the easiest way to do it? 

Thanks fo the help

You are almost there - try this

Appended to: +\w?:\\+(G_volume)*\\*Streamserve

Thank you so much, it works!

Can I have one question tho? What "+" before  \w means? I know after something it means there is a match one or more times.
In this case Is it for whitespace? the /s+ would mean the same then?
Again, Thank you!!

Correct - from your examples there were multiple (2) spaces between the first colon and the drive letter
