Daily Casts: gains 8 credits in four turns
Data Folding: gains 8 credits in eight turns. Turns off when you start installing programs, unless you also spend credits and cards increasing your memory well beyond what you need for your rig.

Basically, don't play this card instead of Daily Casts. Probably don't play it in addition to Daily Casts unless you are playing a deck that will stall the game out incredibly long AND has excess MU (MemStrips or some sort of Ekomind combo)

This is a pretty tough sell. Even if a magical fairy summons a copy of the card from the aether into your HQ at the moment you're ready to install it, it's still challenging to make it pay off: it costs a click to install and a credit to rez, so you're breaking even when you've gotten 3 credits out of it and starting to make a profit when you've gotten four or more credits out of it. To do that, you have to stack the ice at least four deep on the server (you can only get three credits' value at most out of the first three pieces of ice). How often are you able to afford the time and cards to stack four ice on one server? Answer: not very often.

And in the meantime, you probably don't have a magical fairy to summon the card for you, so its trash cost of 1 makes R&D and HQ more vulnerable. At least it has a nice IT Crowd reference for flavor text.
