Methods and program products for communicating file modifications during a collaboration event

摘要

One example method for communicating a file modification during a collaboration event includes steps of a first computer communicating a file modification status request to a second computer, the status request including at least a file identifier and a file property. The second computer uses the file identifier from the request to identify a current property of a corresponding file. The second computer compares the current file property to the file property from the status request and communicates a response to the first computer when the current property does not match the property from the status request.
