It's main use is within IF and Evaluate, preventing them from treating strings as expressions and trying to evaluate them (hence the name : delay evaluation).ColdFusion will try to evaluate anything within pound signs first, using DE() allows you to have it evaluate the internal parts surrounded by pound signs later, rather than trying to evaluate the whole thing as an expression.
I use evaluate() and de() mostly for dynamic logical processing (implementing rules and complex data filters) but I find the writing dynamic code using CFFILE and including it is much faster for large/high-volume or complex applications. After reading this explanation I wonder if I truly understand it as well...
