File thumbnails dissapear after synchronization with Onedrive

[bkoeseVJRTT]

Hi Everyone,

Currently I'm using Inventor 2025 and storing all my files on OneDrive. As the title suggests, I'm not seeing Inventor thumbnails in Windows Explorer or the Open dialog box; which is quite inconvenient. 

I followed the steps outlined in this article: Inventor files thumbnails do not appear in the Inventor Open Dialogue box; however, the issue remains unresolved. Interestingly, this problem doesn't occur when I save files to a non-synced folder or when I disable OneDrive. In addition, I can see a thumbnail in every part when I check the properties of the file in exporer, which tells me that a thumbnail is being made. 

I hope anyone knows how to fix this issue. 

Kind regards, 

Bart.

I'm following this.

We also use a OneDrive to sync a library of parts.

With me this works fine and I can see the thumbnails from within Inventor and Explorer.

My colleagues however have the same problem as you describe and have tried pretty much everything there is to get it fixed without success.

It's going so far, that at the moment I'm not even updating to windows 11 (they have) because I'm afraid it will mess up mine as well 😅

So maybe it can be useful information for your question, I'm on windows 10 with a OneDrive build 24.186.0915.0004

Hi! I suspect this could be OneDrive setting related. I don't think it is related to the application. Someone mentioned that disabling "Save space and download files as you use" option in OneDrive may fix the missing thumbnail issues.

Many thanks!

Hi Johnson,

We thought the same thing, but we've set all the setting identical and all files are fully synced and downloaded on all of our pc's. So in terms of OneDrive our machines are identical.

Yet on mine the thumbnails are displayed and with my team members they are not... We already went as far as creating separate image files of the thumbnails which then do get displayed next to the parts which is a very poor work around.

Still seems like OneDrive isn't able to access the thumbnail image inside the file. Is there any way to extract the thumbnail from the file?

Dear Johnson,

Thank you for your response. Unfortunately, I had already turned off Files on Demand, but this did not resolve the issue. Other files, such as PDFs, images, and PowerPoint documents, display thumbnails correctly. The problem seems to occur only with Inventor files, which makes me think it might be specific to Inventor.

Any suggestions you might have would be greatly appreciated.

Hi! Here is another related discussion on Microsoft Community.

It seems that OneDrive does have trouble displaying non-generic file types. There are a few tips offered in the above thread. Please take a look.

Many thanks!

Thanks again John,

Unfortunately no solution was shown in here. I will keep following that topic.
