Huge temp files created during development and previewing

I just previewed one slide with quite a few layers and here you can see all the temp files created. After deleting them I saved the file and they came back again.

The images on each layer are like 50-60Kb, so they are not huge files.

Hi Rick,

It sounds similar to a situation described here that we've reported to our QA team, but that user was receiving an error message. So before we say that you're running into the same thing I'd like you to check into the following items:

- Have you already looked into the guidelines here in terms of working on your project files? I can see that it's saving to the C drive, but please also check the length of the file path and file name. 
- You may also want to look into the repair steps outlined here. 

This problem seems to have started after installing the latest update last week. The working folder is C:\Vodia, and I publish here as well.
I can't understand why the file is 240,000 KB, even after I stripped it down to just a few slides. But those temp files appear 1. When you preview 2. When you save the project.
I did see a recovery file when I had a crash as it would not allow me to save it anywhere at all, saying there was not enough disk space (remote 2TB hard drive or a network drive).

I just uninstalled and re-installed Storyline, then opened and saved my project. There are 27 new temp files again, C:\Users\zus0205\AppData\Local\Temp, plus the log files for the uninstall/re-install.

I made a screen recording of the issue to try and demonstrate the issue. I still can't understand why the file size is about 240MB for 7 slides with some screen capture images that are about 50-60KB each.

Hi Rick,

Thanks for the video. So you're not seeing the error message as that thread described? Also, I see that it mentioned the OSCdrive -but there are some characters before that that seem like your C drive is a sub folder of something else? Can you try saving to your desktop just to help rule that out entirely? 

Hi Rick,

Thanks - just wanted to confirm as it was difficult to tell where it was located based on that video and I wasn't sure if you were using a network drive or VM that may not be entirely local. 

Since Storyline is not crashing and you're not receiving the error message, I'm not certain that this matches the issue I previously linked to. I know I already asked you to do the repair steps above, but I'd like to have you go through the more involved repair options outlined here. If you're still having an issue with a lot of extraneous files being created can you connect with our Support team? 

Well, I started a new project and then copied most everything to the new project. It is now 1200 KB instead of 242000 KB. It also no longer creates those crazy temp files.

The only thing I did not bring in was the entire slide that had about 20 layers on it. I just copied what was on the main layer.

Just something corrupt in that file I guess. Thanks for the help!

Thanks Rick for the update - and our QA team is aware of some issues with the temp files being created, but it sounds like you're issue may have been different. In case you see it again, there is some documentation of further troubleshooting steps in the bottom of this article. 

I am also experiencing these issues, I'm up to 50GB in my "AppData\Local\Temp" area.
