This study shows that information organization is a process of construction and that the participants' social foundations are reflected in the way they view and organize their files.Originality/valueThis study makes a unique contribution to the field by explaining the social aspects of personal information organization. The findings of this study deepen our knowledge of personal information organization by providing different ways to understand how and why people organize their files in certain ways, and by showing that this is not just individual behavior.
