- A 64 bit system has 2 sets of programme files. "Programme Files" are ones that are designed for, and use, 64 bit. Many programmes are only designed for 32 bit - they run happily on a 64 bit machine, but are in the "Programme file (x84) folder. They go there automatically. A few programmes, such as Photoshop CS5 install in both formats - too long to explain here but some features only run in one version or the other (No TWAIN drivers for the 64 bit version).
- In my case I keep all programmes in a C: Partition, but all data in another (F) partition. I use the old folder system - " My Documents" with sub folders such as "My pictures", "My Word Documents" etc.
- If I were you I would keep the SSD purely for programme files - it should be more than big enough (my C partition is using only 68 gig for many programmes. Then you could use your D drive for Data that you generate. This has the further advantage that for back ups you can make an "image" of the C drive using a special programme like Acronis True Image but use a quicker "Mirror Copies" of your data drive using something like Freefilesynch or SynchToy.You will need yet another, say USB drive, for such back ups.
- If I were you I would look up, on Google, the use of libraries in Windows, as they are, in my view, a bit complicated, but libraries are not, themselves, folders but an index of where folders are.
