Can current versions of Word still open DOC files?

Yes, Word 365 opens .doc files in Compatibility Mode, but newer features like modern charts and co-authoring stay disabled until you convert. Microsoft has kept read support while steering everyone toward DOCX since 2007.

Why do some upload forms reject DOC files?

The old binary DOC format was a favorite carrier for macro viruses, so many web portals, mail gateways, and HR systems now accept only DOCX or PDF. Converting the file takes seconds and clears the security filter.

Will converting DOC to DOCX change the layout?

For typical documents, no; text, tables, and images carry over exactly. Files using WordArt, the legacy equation editor, or embedded macros may need touch-ups, and macros specifically require the DOCM format rather than DOCX.
