In this paper, I argue that singular thought about an object involves nondescriptive or de re ways of thinking of that object, that is, modes of presentation resting on contextual relations of ‘acquaintance’ to the object. Such modes of presentation I analyse as mental files in which the subject can store information gained through the acquaintance relations in question. I show that the mental -file approach provides a solution to a vexing problem regarding the communication of singular thoughts: If singular thoughts depend upon contextual relations to the objects of thought, how can they be communicated across contexts? What makes communication possible when the speaker and the addressee do not stand in the same contextual relations to the objects the speaker’s thought is about?

Mental files serve as individual or singular concepts. Like singular terms in the language, they refer, or are supposed to refer. What they refer to is not determined by properties which the subject takes the referent to have (i.e. by the information stored in the file), but through relations to various entities in the environment in which the file fulfills its function. Files are based on acquaintance relations, and the function of the file is to store whatever information is made available through the relations in question. I offer a typology of files. The most important distinction is between proto-files and conceptual files. In contrast to proto-files, conceptual files can host not only information derived through the specific relation on which the file is based, but also information about the same object gained in some other way. In this framework identity comes into the picture twice. (i) Identity is presupposed when two pieces of information occur in the same file. Such 'presumptions of identity' ground the linguistic phenomenon of de jure coreference, which takes place when two singular terms, or two occurrences of a singular term, are associated with the same file. (ii) Judgments of identity work by linking two distinct files, thereby enabling information to flow freely between them. This corresponds to de facto coreference. (Linking is not merging ; identity judgments have the effect of merging files only when the files belong to a very specific category, that of 'encyclopedia entries' -- a type of conceptual file based on a higher-order relation rather than on a specific acquaintance relation.) In the last part of the paper I will discuss, and attempt to rebut, two objections to the mental-file account. According to the first objection, the account is circular ; according to the second objection, de jure coreference cannot be accounted for it in terms of identity of the associated mental files because de jure coreference is not a transitive relation.
