Windows Vista SP2, (uncompressed 100 GB Drive C is 50% full and Windows file indexing is on):
Drive C, where all the program files, \Windows folder and all my data is located is half full, enjoys fast disk access. I also have disk caching optimization turned on. If I were to compress all the files on drive C, would disk access be faster?.. At what point (% full) should I consider compressing drive C?.. Should I only compress the data or all the files on this drive?
