Here is an interesting problem I cannot seem to find an answer to. I have a client that has several files from email message exports that do not have a file extension (e.g. PDF, DOC). These files, when clicked, open in IE. Essentially, these are text files, but the email client does not attach any file extension.
The library shows the file as does DataView web parts. In both cases I can click the file and it opens in IE no problem.
My problem is with searching/crawling the content. It is almost like the crawl ignores the files since it does not have a file extension. Is this a crawl rule or file type issue? Anyone know how to resolve?
