10. The method of claim 9 , wherein classifying the plurality of instances of the electronic file based on the role within the organization comprises classifying the plurality of instances of the electronic file as important to at least one of:

the user;

an organization; and

a department within the organization.

11. The method of claim 1 , wherein determining whether the user considers the one or more instances of the electronic file to be important comprises analyzing the state of the user's electronic workspace while the user was interacting with the one or more instances of the electronic file.

12. The method of claim 1 :

further comprising:

determining that the plurality of instances of the electronic file is part of an enterprise workflow; and

identifying a plurality of users involved in the enterprise workflow; and

wherein classifying the plurality of electronic files comprises classifying the plurality of instances of the electronic file as important files based at least in part on determining whether each user in the plurality of users considers at least one instance in the plurality of instances of the electronic file to be important.

13. The method of claim 1 , wherein collecting the information about the physical state of the user comprises collecting information from at least one wearable device worn by the user.

14. The method of claim 1 , wherein the software security system comprises at least one of:

a data-loss prevention system;

a file backup system; and

a file-integrity management system.

15. A system for classifying electronic files, the system comprising:

an identification module, stored in a memory of the system, that:

identifies a plurality of instances of an electronic file comprising a plurality of versions of the electronic file; and

in response to determining that a user from among a plurality of users is interacting with one or more instances of an electronic file by opening the one or more instances of the electronic file on a computing device, causes a file-categorization system to evaluate the one or more instances of the electronic file for importance;

a collection module, stored in the memory, that collects, via at least one user-state monitoring device, information about a physical state of at least one user while the user is interacting with the one or more instances of the electronic file;

a determination module, stored in the memory, that determines, based on the information about the physical state of the user while the user was interacting with the one or more instances of the electronic file, whether the user considers the one or more instances of the electronic file to be important;

a classification module, stored in the memory, that:

classifies, by the file-categorization system and based at least in part on determining whether each user in the plurality of users that has interacted with the one or more instances of the electronic file considers the one or more instances of the electronic file to be important, the plurality of instances of the electronic file as important files; and

in response to classifying the plurality of instances of the electronic file as important files, notifies at least one software security system that the plurality of instances of the electronic file are important files, thereby causing the at least one software security system to prioritize actions involving the important files over actions involving electronic files that are not classified as important files; and

at least one physical processor configured to execute the identification module, the collection module, the determination module, and the classification module.

16. The system of claim 15 , wherein the determination module determines whether the user considers the one or more instances of the electronic file to be important comprises calculating, based on the information about the physical state of the user, an attention score that represents a numerical approximation of whether the user considers the one or more instances of the electronic file to be important.
