I think you are talking about a version of EEGLAB which is still in 
development (the version that has been used at the workshop and will be 
released most likely in January). The ".dat" files containing data 
replace the ".fdt" files . In the dat files, the data is simply 
transposed when compared to the ".fdt" files. The reason is that this 
allows to read one channel at a time from disk (and will allow in the 
future to process multiple datasets very fast even if the data remains 
on disk).

About your question, you may use the menu File > Maximize memory and 
select the option to write all data in one file.
