Multiple user access to files with Formatting and I/O Library

I'm developing a data-logging application using LabWindows/CVI 2013.

This is for a life test that will run for 2 years uninterrupted.
It will save data at a rate of about 20 bytes once per second.
I figured the app would open, write, close every sample.

I would like to keep the data logging application simple and build some sophistication into a separate application for analysis and progress tracking.

I'm thinking about using the file access functions in the Formatting and I/O Library.
OpenFile, CloseFile, ReadFile, WriteFile etc.

My question is:
Using this library, will the analysis application be able to be used by multiple users to open the log data file for reading and analysis while the logging continues?
I plan to put the log file on a network drive that is accessable throughout the company.

No writing to the log file will be allowed.

Also would like the logging app to periodically copy the log file to a backup.  Again this is while logging continues.

Thanks,
Kirk
