I have a fairly new installation of Windows 11. My Dropbox is set to Online, so that it downloads the files as needed, and I am seeing the following strange behaviour: * Open Explorer with Preview Pane turned on, Details view. * Navigate to a folder on my Dropbox. * Click on a PDF that has the 'cloud' symbol. The preview appears in the Preview pane and the 'cloud' symbol changes to the 'green tick' symbol. I notice that the previewer is Microsoft Edge. * Click on another PDF - the same happens, I see the preview. * Click on the first PDF again - NO PREVIEW. The preview pane is blank. If I right-click and download a PDF first, I cannot preview it at all. If I copy the file to a local folder I can preview it fine; I notice that the local previews do not say Microsoft Edge. So, Windows 11 can't preview downloaded PDFs in Dropbox folders???

Explorer preview stops working after the first time you click on a PDF file in Windows 11

I have a fairly new installation of Windows 11. My Dropbox is set to Online, so that it downloads the files as needed, and I am seeing the following strange behaviour:

Open Explorer with Preview Pane turned on, Details view.
Navigate to a folder on my Dropbox.
Click on a PDF that has the 'cloud' symbol. The preview appears in the Preview pane and the 'cloud' symbol changes to the 'green tick' symbol. I notice that the previewer is Microsoft Edge.
Click on another PDF - the same happens, I see the preview.
Click on the first PDF again - NO PREVIEW. The preview pane is blank.

If I right-click and download a PDF first, I cannot preview it at all. If I copy the file to a local folder I can preview it fine; I notice that the local previews do not say Microsoft Edge.

So, Windows 11 can't preview downloaded PDFs in Dropbox folders???

Hi @MirandaP, how are you today?

Interesting behavior. Could you also send me a few screenshots, in order for me to have a visual of what you described?

Looking forward to your next response!

MirandaP

Sure.

Initial state. Note that all files are 'online only'.

After clicking on the file the first time:

After clicking on another file. This one previews OK too.

PDF problem - 3 - after clicking on another file.png

After clicking on the first file again. Note that the preview pane is empty.

After copying the file to a local folder. Preview shows as expected.

PDF problem - 5 - file previews OK in local folder.png

Excellent job with the screenshots @MirandaP!

That's odd. Which version of our app do you use on your end?

Also, I know that'll sound trivial, but have you tried re-starting your device at all?

MirandaP

I'm on Dropbox v162.4.5419.

I've just restarted my PC and it's doing exactly the same.

Walter

Hey @MirandaP, sorry to jump in, but could you try quitting the Dropbox desktop app and try again?

Let us know if the issue with your previews persists with the app completely closed and we'll take it from there.

MirandaP

After quitting the Dropbox app none of the previews work because none of the files are downloaded.

Most just show a blank page. On some of them (I can't see why) I get an error, 'Hmmm… can't reach this page It looks like the webpage at file:///C:/Users/miran/Dropbox/ [my folder name here] /2022-09-03.pdf#view=FitH might be having issues or it may have moved permanently to a new web address.' with 'ERR_FAILED' underneath.

If I start the app again, click on one file so that it downloads it and shows the preview, then quit the app again, I still cannot preview that one file. However I can double-click on it to open it in Edge, and if I copy it locally it previews OK.

I hope someone can help me, it's really annoying!

Hi @MirandaP! Sorry for jumping in here.

Do you mind if we log a ticket for you, so that we can check this internally?

Let me know if you’re OK with that.

MirandaP

Yes of course. Let me know if I can try anything else or if you need any more information.

Jay

Hi @MirandaP, I've sent you an email, please could you reply to it as soon as possible!

Hello, I'm experiencing issues with PDF files and some png & jpeg which can't use the preview option.

Nancy

Hi @anasperincheeri! Thanks for reporting this.

Are you having the exact same issue as described by the previous user?

What’s the app version and syncing status of your Dropbox app at the moment?

I have tried all REG fixes, choosing apps, to get my files to preview in the preview pane in File Explorer, in Windows 11. No matter what I have tried, no preview is ever made. If I preview a file from Dropbox, copied to a non-Dropbox local folder, the preview works nicely. However, this is NOT a solution - I *must* have the preview feature IN a Dropbox folder. I have made sure that the files are stored locally. Even if I quite Dropbox on my local machine, the preview never works. This needs to be solved or Dropbox is no longer viable, so what am I paying for? I can use all sorts of other cloud storage competitor applications without this problem. I need a solution!

Jay

Hi @NW7US, thanks for bringing this to our attention.

Have you already been in contact with the support team for them to investigate this matter in more detail?

This will help me to assist further!

NW7US

Not yet. Will do so now.
