Those are not files  they don t exist on disk  - they are just names under which some HTTP handlers are registered  Take a look at the web config in  NET Framework s directory  e g  C  Windows Microsoft NET Framework v4 0 30319 Config web config     lt configuration gt     lt system web gt       lt httpHandlers gt         lt add path  eurl axd  verb     type  System Web HttpNotFoundHandler  validate  True    gt         lt add path  trace axd  verb     type  System Web Handlers TraceHandler  validate  True    gt         lt add path  WebResource axd  verb  GET  type  System Web Handlers AssemblyResourceLoader  validate  True    gt         lt add verb     path    AppService axd  type  System Web Script Services ScriptHandlerFactory  System Web Extensions  Version 4 0 0 0  Culture neutral  PublicKeyToken 31bf3856ad364e35  validate  False    gt         lt add verb  GET HEAD  path  ScriptResource axd  type  System Web Handlers ScriptResourceHandler  System Web Extensions  Version 4 0 0 0  Culture neutral  PublicKeyToken 31bf3856ad364e35  validate  False   gt         lt add path    axd  verb     type  System Web HttpNotFoundHandler  validate  True    gt       lt  httpHandlers gt     lt  system web gt   lt configuration gt    You can register your own handlers with a whatever axd name in your application s web config  While you can bind your handlers to whatever names you like   axd has the upside of working on IIS6 out of the box by default  IIS6 passes requests for   axd to the ASP NET runtime by default   Using an arbitrary path for the handler  like Document pdf  or really anything except ASP NET-specific extensions   requires more configuration work  In IIS7 in integrated pipeline mode this is no longer a problem  as all requests are processed by the ASP NET stack

from Google  An  axd file is a HTTP Handler file  There are two types of  axd files    ScriptResource axd WebResource axd   These are files which are generated at runtime whenever you use ScriptManager in your Web app  This is being generated only once when you deploy it on the server    Simply put the ScriptResource AXD contains all of the clientside javascript routines for Ajax  Just because you include a scriptmanager that loads a script file it will never appear as a ScriptResource AXD - instead it will be merely passed as the  js file you send if you reference a external script file  If you embed it in code then it may merely appear as part of the html as a  tag and code but depending if you code according to how the ToolKit handles it - may or may not appear as as a ScriptResource axd  ScriptResource axd is only introduced with AJAX and you will never see it elsewhere  And ofcourse it is necessary
