Every department receives, archives or inherits files it cannot open without the original software. TelaViewer displays them all in a single Windows application, installed nowhere, that works entirely on the computer and never modifies anything.
TelaViewer displays all formats. TelaViewer Pro adds the checks, exports and extraction that departments need to work with the data.

Viewing a document no longer requires the software that created it. Specialised licences (office, desktop publishing, CAD, accounting, databases) stay reserved for the people who create or edit the files.
TelaViewer works entirely locally: no connection, no account, no online service, no statistics. The files you view are sent to no one.
Files are opened read-only and never modified. No program, macro or script contained in a file is ever run; attachments, shortcuts and programs are shown as information sheets.
Word 6 and Lotus documents, Access 1.0 or Paradox databases, Outlook Express mailboxes, archives and virtual disks: files produced by retired or abandoned software stay readable.
