VBScript to loop through all files in a folder 4 answers

I have this VBScript mainly for replace function for multiple text files.

Const ForReading = 1
Const ForWriting = 2

But this kind of code is taking too long (since its a specific filename based) and repetition of the same replace function, I would like to ask for a help on how to make replace function loops for all the files in the same folder.

A big appreciation for the answer.

Set fso = CreateObject("Scripting.FileSystemObject")
Set fldr = fso.GetFolder("C:\windows")

Set Fls = fldr.files

For Each thing in Fls
    msgbox thing.path
Next

also set contents = thing.readall.
