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.
