Supported file formats

Lookeen searches the content of your documents, not just their names – on the PC with Lookeen Desktop and centrally with Lookeen Server. These are the formats Lookeen knows and shows in its “File type” filter.

By content, with a preview

Lookeen searches the content of your files and shows where it found it.

Full text from the document

Lookeen reads the text of Office files, PDFs, emails and many other formats. File names are always searchable, also for formats without text.

Preview with highlights

Office documents, PDFs, text files and images open right in the preview, with your search terms highlighted.

Scanned documents

Optional text recognition (OCR) makes scanned PDFs and images searchable.

All formats by category

The list matches the “File type” filter in Lookeen. Beyond these, Lookeen reads many rarer formats.

Frequently asked questions

Which file types Lookeen indexes and how you choose them.

Can I choose which file types are indexed?

Yes. Lookeen Desktop has the file types in its settings under “Index”, Lookeen Server per source. That keeps the index lean, for example without source code or videos.

Are email attachments searched?

Yes. Attachments are indexed like files of their own, also in PST and OST files and in .msg and .eml files on a drive.
