It is important to know

Before choosing a Donau A4 green button folder, it is useful to consider how often you will take documents out of the folder and whether you need it more for archiving or for mobile use. The most important practical decision is whether the button closure method provides you with adequate protection and quick access in your work routine. Also pay special attention to compatibility with your existing document organization system if you use different types of folders in your office.

• A button folder is especially useful when protecting documents from falling out when being transported between locations or to meetings is crucial.
• Due to its more closed construction, it allows for clearer physical separation of contents, but inserting or removing individual sheets is slightly slower compared to open folders.
• Color classification, such as green, can help with faster visual organization by projects, departments, or document types if this system is consistently established.
• To effectively organize different phases of work, it often makes sense to combine several types of folders and also take into account the space limitations of the archive or work desk.

In practice

🟢 Archiving and protecting project documents

A button folder offers adequate protection for business documents, which should be stored safely and quickly accessible, without the risk of mechanical damage or loss of content.

🟢 Transfer to meetings or between locations

Due to the locking system, it is very suitable for transporting documents, as it reduces the chance of sheets being lost or scattered during transport.

🟡 Use for frequently changing or flipping through documents

Due to the way it closes, inserting and removing individual sheets is not as fast as with open folders, so for scenarios with frequent changes, it is better to consider an alternative.

🟢 Color coding in the office

The distinctive color allows for easy visual separation of materials, which is useful when sorting documents by department, project, or priority.
