In your example  you prepended your source string with AccountKey  but not your target string    c    c -replace  AccountKey eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR Zd KXoKvSdjlUiiWyVV2 OUFOrVsd7jrzhldJPmfBBpQA     AccountKey DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN WVBJNWzqcQpWtZf10tgFhKrnN48lXA      By not including that in the target string  the resulting string will remove AccountKey  instead of replacing it  You correctly do this with the AccountName  example  which seems to support this conclusion since it is not giving you any problems  If you really mean to have that prepended  then this may resolve your issue

If you ve got V3  you can take advantage of auto-enumeration  the -Raw switch in Get-Content  and some of the new line contiunation syntax to simply it to this  using the string  replace   method instead of the -replace operator    Get-ChildItem   FILEPATH   -recurse  FullName     Foreach-Object       Get-Content    -Raw        Replace  abt7d9epp4   w2svuzf54f         Replace  AccountName adtestnego   AccountName zadtestnego         Replace  AccountKey eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR Zd KXoKvSdjlUiiWyVV2 OUFOrVsd7jrzhldJPmfBBpQA     AccountKey DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN WVBJNWzqcQpWtZf10tgFhKrnN48lXA          Set-Content          Using the  replace   method uses literal strings for the replaced text argument  not regex   so you don t need to worry about escaping regex metacharacters in the text-to-replace argument

-replace  does a regex search and you have special characters in that last one  like    So you might use the non-regex replace version like this    c    c replace  AccountKey eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR Zd KXoKvSdjlUiiWyVV2 OUFOrVsd7jrzhldJPmfBBpQA     DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN WVBJNWzqcQpWtZf10tgFhKrnN48lXA
