Programs have to manage their own writing to EEPROM. Look in the Object Exchange for "Basic I2C Driver 1.3" and read the comments at the beginning. The EEPROM deals in individual bytes rather than files. The Driver includes routines to read and write bytes, words, and longs given an address.

I think the object posted in the first post doesn't release the I2C lines. See post #5 to see what I've done to fix it.
I'm not sure if the version posted is the same one I tried out years ago. The problem might have been fixed.
