boosted1g :
The OP just wants help with the files on this drive, nothing about programs on his old drive.
Then I don't understand why OP wrote ?
How should setup old drive to hold media and use it for certain programs? Should I rename it from local disc and can I delete old program folders/files and old windows folders/files or not?
At the very least, it's not quite clear what is intended so I thot best to cover all bases. I also wanted to make the OP aware that it is advisable to keep the windows install in case SSD dies. We set up every new build this way with the OS on both the SSD and HD so failre of one still allows one to boot from the other. The only way that's possible tho is if he is advised before he deletes the necessary files.
If he move all the programs on the SSD, (that wasn't stated), and he has at least a 240 GB SSD, then I would revise as follows:
a. Copy each folder for programs one wants to keep from D:\ProgramFiles to C:\Program Files. This will retrain all user file links, menu customizations etc.
b. Then install the program over itself to set up registry
None of our users every have to deal with ProgramFiles directories as for the last 25 years, every machine has been set up with only the OS on its own partition. Makes it a bit easier when upgrading an OS or moving to an SSD
It also keeps any licensing information, product keys etc. Id also add.... if ya haven't done so already... and if you can still boot to the OS install on the HD...
Boot to the OS on the HD and run Belarc Advisor, save or print the section which includes all licensing information / product keys. Keep in a safe place.
