Fix-FileName.ps1

1. <# 
2. .SYNOPSIS 
3.     Defines a function to remove 'invalid' characters 
4.     from a file name. 
5. .DESCRIPTION 
6.     Some programs do not like certain 'invalid' characters 
7.     in a file name used by that application. The function 
8.     takes a look at each the file name and replaces some invalid 
9.     characters with '-'. 
10.  
11.     This function takes a file name and 'fixes' it and returns 
12.     the 'fixed' file name. Needless to say the characters to match 
13.     and what to replace them with is an application specific decision!
