If you actually use Doitsu's wonderful epubcheck plugin for Sigil, you would be able to easily click on the report rows in the Validator window and navigate directly to where the error is in Sigil.
My guess is you tried to modify your file extensions from '.htm" to '.xhtml' somehow and did not use Sigil's rename to do that and so "lost" your files. You just can not change them in the opf.
So there never was a problem in Sigil.
Please next time, answer the questions about version of Sigil or Platform as these are important.
And next time actually explain what you did (the exact sequence of events, etc). So that people can actually help.
