THINGS YOU SHOULD KNOW ABOUT…™ ORGANIZING FILES IN THE CLOUD 1. What is it?

Encryption helps, of course, but is not a fail-safe solution. Moreover, cultural or regula- tory climates can be an obstacle—in some countries, no institu- tional data may be stored on servers outside that nation, making a cloud file service illegal. In any case, education and awareness among users are necessary to minimize file-management activi- ties that could expose private information, whether personal or institutional. Long-term viability of the file-service provider might be a concern, though services that maintain a local file on separate devices should guarantee continued access to a user’s files. Users must typically pay for storage capacity above a certain threshold, placing a financial burden on some, and some services limit the size of individual files.
