Files very slow to open

Is there a checklist of things I can do to get the files to open quicker? I've deleted the picture cache but it doesn't seem to help and when it opens, it needs more time to recreate the clip images. Of course I'm impatient! but that's not the problem, my files are taking minutes to open.
 
I opened a file before sending this message and it still isn't open. Some of the time can be accounted for by the plugs in the file but taking minutes is ridiculous.

Hi. Does this happen on every project? What kind of HD /SSD do you save projects to? Which plugins / soft synths do you use? Does this happen if you open SONAR in safe mode (Shift + double click on the icon)? Say no to plugins.
All the best.

I have also noticed that the time to open projects has increased dramatically recently.  I haven't been able to identify why. I'm using Windows 10 with the most recent updates, and I installed the newest version of Sonar Plat to see if that helped, but it didn't.  I did notice that the projects that take the longest to load have more than one screen set.
I started putting some of the largest projects on an SSD, but it didn't make any difference in load times.

Aspen:
You just described my problem exactly. I think my solution is to open all the troublesome files by any method and replace each instance of Kontakt by removing and replacing. That should fix it for me, but only if the Kontakt is the issue.
 
Chuck:
I stopped Sonar from PIM-ing many years ago so I'm sure that's not it, even if it was, it only takes about 20 seconds to run. I tried Safe Mode but I got a message saying, 'Sonar will now personalize your data.' I baled out because I didn't know what entailed or how to reverse it if it caused problems. I thought it was already personalized...
 
However, I feel sure that the upgraded Kontakt is the cause. It's the only thing that changed and I found at least one file that won't open at all. Most of my songs still have an instance of Kontakt and in the past I've got a message when opening the file to the effect that 'system can't find the old Kontakt reg keys' along with a suggestion for the new keys. I accept the suggestion and all is well. Maybe something went wrong with my Kontakt upgrade and the system doesn't know what to suggest and can't resolve the old - that's my theory.

Hi,
 
Thanks for bringing this up. I too am seeing the same as projects (not all having NI instruments) are taking longer to load...
 
Best,

That's not safe mode, that's re-personalizing sonar. (but what have you got to lose ?) it doesn't change anything except set up files.
 
Safe Mode dialog
Opening a file in safe mode opens the safe mode dialog box, which asks you, one plug-in at a time, which of the file’s plug-ins to open each. If you think one of the plug-ins is preventing the file from opening, choose not to load that plug-in. You can also try loading only one plug-in, closing the file, and then loading 2 plug-ins the next time you open the file, etc., until you isolate the bad plug-in.
 
 
Note: Safe mode is activated when you open a file while the SHIFT key is pressed.

Chuck - which version of SPlat are you running?

 
The very latest version

I think I have a handle on it. Kontakt was the culprit, I started by saying NO to just Kontakt and the file opened right up. I removed and replaced Kontakt so that now the file has the correct address of the new version and resaved. It opened up just fine. Now for the other 300 songs!

Normally, I'd say that could be true but I've had the same files working for over a year with no changes to anything except the version of Kontakt. After upgrading Kontakt, I'm usually prompted for the new reg keys or mem address, this time I wasn't for unknown reasons. 
 
It also looks as if the .cpw file 'remembers' plugin settings so maybe it's not as bad as I thought. 

Are you 100 positive you don't have any Anti Virus running and are all up to date with Windows ?
Trust me when I say Anti Virus will rescan the same files unless they are added to the exception list.
I had a case about 2 months ago where Sonar was very slow and unresponsive at times. it turned out I needed to update my virus definitions. I just became lazy and set it to manual (to prevent scanning while im working in Sonar)
once I updated and did a cold reboot. it was like a new computer. For some odd reason my Anti Virus was sucking up huge amounts of CPU until I completed the updates.
Also don't under estimate the power of shutting down your PC for the night and restarting it in the morning. sleep mode is not the same thing.

If you guys think you have narrow this down to Kontakt, I would contact <- no pun intended) NI and let them know.
 

revnice1, when you create a new project, does it take a long time to be created ?
 
I tried using SHIFT + double click on a file but I can't have the Sonar Safe Mode (I have the Personalization message), how did you do please ?

Ok thanks.
 
I find the culprit which is not Kontakt or other plug-ins as in Safe Mode, I click Yes to All and it opens instantly. It's the Browser that makes my files take a while to open (Safe Mode prevents the Browser to be opened).
 
If in a file, the Browser is docked (minimized or not) or undocked but opened, it takes a while. If I undock the Browser and close it, next time I open the file, no problem but if I click on B to open it... long time. Once the Browser is opened, I can minimize/maximize it with B with no problem but if I close it... again a long time to open.
 
It also explains why a file made in Platinum, saved in 8.5 and reopened in Platinum is loaded instantly as the Browser didn't exist in 8.5.
 
I found this but I have no floppy disk listed : https://www.cakewalk.com/...wser-slow-on-some-comp

What browser? You mean an internet browser?

I guess he means the Media / Plugin Browser (shortcut "B") in SONAR.

I have tried all of these suggestions, and have upgraded Kontakt 5 to the latest version, and it has made no difference in the load times of my test project. 
 
IIRC,  my slowdown first occured when I started using multiple screensets on this project.  Other projects without multiple screensets load much faster.
 
I'm curious if those of you with fast load times are using multiple screensets in your projects?

The other thing I just noticed in the past few days is when scrolling left and right in the track view, it has become very slow and stuttering.  It used to be very smooth and fast.  I have updated my graphics drivers (Nvidia) and it did not fix the issue.
