Replace special character in powershell

Hi All,
I am very new on powershell forum here. For one of my daily manually find and replace task i want to create a powershell script to find and replace some network location and replace with new one.
Like :-
To find : \filedep\iservershare\DCSVWA
Replace with \EGSISFS01\VolksWagon\DCSVWA

I am able to replace text without any special characters but for above I am getting regular expression error.
And also after replacing above string i want to save result in a text file which logs records of files which have been updated.

Thanks
Akash.

I got the solution here:-
$c = $c -replace [regex]::Escape(’\filedep\iservershare\DCSVWA’),(’\EGSISFS01\VolksWagon\DCSVWA’)

$a = “\filedep\iservershare\DCSVWA\somefilename.txt”
$a = $a -replace “\\filedep\iservershare\DCSVWA”,"\EGSISFS01\VolksWagon\DCSVWA"
$a

The backslash is an escape character in Regex.

PowerShell’s -replace operator uses regular expressions, and also works well on collections. If your $c variable happens to just be a single string (not a collection of strings), though, you can also just use the Replace() method of the String class, which keeps regex out of the picture:

$c = $c.Replace('\\filedep\iservershare\DCSVWA', '\\EGSISFS01\VolksWagon\DCSVWA')
