I have a page layout, PeopleSearchResults.aspx programmed by someone else. It contains the following tag for a SharePoint refine people search results control.
Title="<%$Resources:sps,RefineByTitle%>"
Where on earth/SharePoint do I look to find the string that code references?
The particular file you specified, sps.resx is actually in 12\CONFIG\Resources (but there's a bunch of others in 12\Resources).
Where are SharePoint resources strings located.
The provisioning resources are located in the 12 hive in ..\12\Resources.
The 12 Hive is a directory most often found at: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12.
So to answer your question, assuming your sharepoint install is on drive C, look in the C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\Resources folder.
Also, look in the App_GlobalResources folder for your web site. (determined from IIS Manager)
="<%$Resources:sps,RefineByTitle%>"
sps (.resx) is the name of the resource file in 12\Resources (there may be several with extra bits such as .en-us.resx, fr-fr.resx etc if you have multiple languages supported) and RefineByTitle is the key of the language entry in that file.
