Hilandermak,
The OS and Cakewalk program go to the SSD. Files that you will edit often (Cakewalk as well as others) go to the HDD. When you first install Cakewalk go to Edit pull down menu and select Preferences. In the Preferences select File Folder Locations. You will see the Cakewalk files that you are allowed to move. Set up folders on the HDD for the files you want to move. Then go back to Edit/Preferences/FileFolderLocations to change the file path to the new drive. The obvious files to put on HDD are:
Cakewalk Project files for CWP, CWB AND MIDI files for Cakewalk projects
Wave files for Wav, AIFE AND MPEG files to import into Cakewalk
Video files for AVI, MPG, MOV video files for import into Cakewalk
Play lists for audio playlists of your Cakewalk Creations.
There are several other Cakewalk files you can move but you need to ask yourself if you will be editing them a lot or just adding to them infrequently and in small quantities. eg. CAL, StudioWare, Step Sequence files if your a keyboard player.
Keeping your SSD from being bloated requires some diligence. Here are a few. The how to's are on the web.
Disable frefetch and superfetch
Limit the paging file on C:\drive
Move the locations for User TMP and TMP files and the System TEMP and TMP files
System protection for C:\drive need a limit set for how many restore points you want to keep
Turn off Hybernation thru the command prompt, this also shuts off Fast Start
Turn off windows indexing service for C:\drive but keep it on for HDD
Turn off C:\drive file compression and defrag in disk management
Depending on your SSD, enable write cache buffer and buffer flushing, see vendor specs
Change the default location for user files this is the big one.
Change the default location for download files this is a big one too.
This should get you started. I'm sure there are others the rest of the forum can help with.
Enjoy,
Forest
