Blue means finance until the blue folders run out. Then one year's invoices become green, while green already means customers. A color system that depends on remembering exceptions soon stops helping. Start with names that remain useful when every folder is the same color.
Choose the words someone would use to ask for the file. 'Equipment warranties' is easier to interpret than 'Admin 4.' Keep related names consistent: if one folder begins with a supplier name, use that approach for the other supplier folders rather than mixing company names, contact names and product categories.
A short list of current files can reveal where the structure is becoming too fine. If several folders contain one sheet each and are always retrieved together, they may belong in one folder with simple dividers. On the other hand, a bulging folder labeled 'Miscellaneous' probably needs a clearer boundary.
Use color only where it adds a visible distinction that is worth maintaining. One color for active work and another for completed work can be easier to understand than a separate hue for every subject. Keep the written label sufficient on its own so that color vision, lighting or a replacement pack does not determine whether a file can be found.
Label for the next person
Leave enough room on the tab for the complete meaningful name. Abbreviations that are obvious today can become puzzling a year later, especially in a shared office. Include a date range when the contents have a natural period, but avoid adding a year merely because a folder was purchased that year.
Try the naming scheme with a few actual documents before labeling the entire cupboard. Ask where each one would go and where someone would look for it. If the answer depends on a long explanation, change the folder boundary or name while the system is still small.
Keep spare labels and blank folders together. Retire outdated labels when a folder changes purpose rather than placing a new one where the old name remains visible. A modest, consistent filing system needs occasional attention, but it should not require its own reference manual. The test is whether a person can put a document away and another person can find it again.
