I am building a sync app for enterprise users, and would like to test it with a large collection of real-world business files. Typically the kind of files you would find in a company's file server. It would also be useful when performing demos.

Since every company is different, I would like a sample dataset containing a representative range of files:

  • Invoices
  • Contracts
  • Requests for proposal, commercial proposals
  • Marketing material and branding design files
  • Internal memos
  • Generated reports
  • Scanned documents
  • Accounting files
  • Software installers and licences
  • Documentation for company tools
  • Events pictures
  • etc

Possibly also some domain files like product design documents, CAD files, etc.

It MUST be under an open license.

I think there are too many diverse filetypes to expect a good set. For example, wikipedia has many listed at List of File Formats, with this disclaimer:

This is an incomplete list that may never be able to satisfy particular standards for completeness.

But, if you make a list of possible extensions (see here from a list of lists, and here for A-E), you can pass them all in a big loop to a search engine with a "filetype:abc" argument (and download the results).

The problem is that I don't know of a search engine that has robust filetype searching. I checked both Google and DuckDuckGo and neither found actual files for the few I checked.

So, this isn't really an answer, but perhaps someone knows a search engine for robust filetype searching. Hopefully that search engine also has a way to filter based on license.

  • "too many diverse filetypes to expect a good set": No, the set of files of pretty much any company would be a good set already. I am not looking for every file type ever created, just an example of what the company next door is using :-)
