What is a CHS file?
System file used by Index Server, a component of the Windows operating system used for searching; saved in a plain text format and contains a list of noise words, which are keywords that are excluded from the search indexing process; located in the C:\Windows\System32\ directory and has the filename NOISE.CHS; used for the Chinese (CHS) noise-word list in Windows.
More Information
CHS files help Windows speed up the process of indexing by removing words that would only create unwanted "noise" in the search results. Example noise words include "the," "or," "it," and "this." An example Chinese noise word in the Windows CHS file is 的, which means "of."

A CHS file contains binary data for ActiveX components that provide functionality for older versions of various Adobe applications, such as Acrobat and Acrobat Reader. It stores information about resources and configurations the component requires to function correctly, such as .PDF rendering and form filling in a web browser or another application.
More Information
Microsoft introduced ActiveX in 1996 as a framework that allows software components to interact within applications, primarily on Windows operating systems. Adobe ActiveX is a legacy technology that was a specific implementation of Microsoft's ActiveX used to integrate its software with other Windows-based applications. For example, Acrobat used ActiveX to extend PDF rendering capabilities to the now-retired Internet Explorer web browser.
NOTE: Altering or deleting CHS files may cause the component to break, leading to the application functioning incorrectly.
