NurViewer · 600+

Your files have more in them.

600+ registered extensions and aliases span documents, books, pictures, media and specialist material. Capabilities are described by level.

SUPPORT, WITH CONTEXT

A memorable number. A readable scope.

The current registry lists 661 distinct extensions. Aliases are counted; this is not 661 complete editors, nor a claim that every format converts or has searchable text.

Dedicated viewing

Displays the main supported content, with format-specific tools.

Basic preview

Reads common structures; complex layout, advanced objects or animation may be simplified.

System / codec dependent

Playback/decoding depends on the actual encoding and platform.

Information inspection

Shows signatures, metadata or bounded content; it does not imply full content decoding.

LOOK UP A FILE TYPE

Find the extension in your folder.

Try PDF, EPUB, RAW or a particular extension, or filter by family.

A FEW IMPORTANT DISTINCTIONS

Viewing and processing have different ranges.

PDF / EPUB and full-text search

PDF text layers, EPUB and supported Office/text content can be searched. Scan-only pages are skipped without automatic recognition. Some viewable formats, including legacy Office and DjVu, are outside current folder content search.

DWG / CAD / 3D

DWG currently offers Windows read-only 2D preview; complex objects and external references can be incomplete. 3D inspection tools vary by format; CAD editing and measurement for every format are not promised.

PST / OST and specialist information files

PST / OST expose container information, not the emails inside. Some fonts, colour profiles and specialist binaries expose metadata only.

Encryption, damage and encoding variants

Registration does not guarantee every subtype. Damaged, encrypted or unsupported variants can report a limitation; an unknown-file inspector is not full format support.
