In addition to a cover letter and a CV, most German applications also include copies of qualifications and references from former employers. It is advisable to provide copies of all certificates to support each item in your CV. A complete application can therefore become quite long, with 20-30 pages not being uncommon. Many people bind their application in a Bewerbungsmappe (application folder), which can be bought in most stationary stores. This will make it easier for people to find the documents and can help to create a better impression.
