Thumbnails not working in Windows 11 with OneDrive about f3d HOT 27 OPEN

Hi @odyskat

I have no access to a Windows 11 computer at the moment so I cant test this right away.
However I see a lot of posts online about general issues with thumbnails on Windows 11. Can you confirm thumbnaisl are working in general for you ?

from f3d.

Hi @mwestphal and thanks for the quick reply.
I checked for a stl file and
I think f3d did not provide a thumbnail (I see a picture like the one below even when I uninstalled it).
I suppose windows provides the image and not f3d.
Hope it helps.

@Meakk tested with Windows 11 and it seems to work great. can you try reinstalling ?

from f3d.

@mwestphal I did it multiple times, same result.
I will try it at home with another computer for comparison.

from f3d.

I tried in a Windows 10 machine at home with no luck for the thumbnails.
Step files were exported from 2 different cad programs to make sure that the problem is not file related.

Note: I use Greek as system locale, not s long ago a Lenovo tool refused to work if the system locale was not English us.
It was hard to find and probably not connected to the thumbnailing issue.

from f3d.

Maybe it's related to one drive? Can you try on a local disk?

from f3d.

Ok, I tried many cases :

Number 1: win10 folder not connected to OneDrive --> works!

Number 2: Win 11 folder not connected to OneDrive --> works!

Number 3: win11 folder in OneDrive fist time copying of the file works, when closed and reopened it's gone.

Comment : I noticed that when the file is stored in SharePoint (for anyone who hasn't used this, it's like Microsoft's business version of OneDrive) and also saved locally on the computer, thumbnails seem to work fine.

from f3d.

I think OneDrive might remove thumbnails to save space (they are saved in thumbs.db file)
I came across this page: https://answers.microsoft.com/en-us/windows/forum/all/video-thumbnails-not-generating-in-onedrive-folder/bf54402a-2306-444a-a986-4642430f6b95
They are mentioning an option Files On-Demand: Save space and download files as you use them to disable. Can you try that?

from f3d.

I have the same install, and no thumbnails what so ever are showing for step files, but whenI copy the complete folder to the C drive: this happens:

and then the thumbnails appear. one by one.
So, when you have a onedrive, it downloads the thumbnails from onedrive (just do the 'see online' option, and you will see which files have thumbnails, and which not) same for PDF, and others, if not local but onedrive (even if 'always keep on this device' is checked), no thumbnail which MS supports)
You have to sync differently with onedrive.

This is the folder after F3D flashed 1000's of times:

red arrows: f3D did not generate a thumbnail, green arrows, it did create a thumbnail.

from f3d.

Regarding the error in the window, it's a new issue.
@mwestphal see

from f3d.

@jeedee23 I think the files without thumbnails are probably the bigger files, can you confirm?

from f3d.

fix incoming, but I think @jeedee23 is using a old nightly.

from f3d.

@jeedee23 If you look at your installation directory, you will find a share\f3d\configs\thumbnail.d\10_global.json config file.
This config file sets the max size limit for generating thumbnails. By default, it's 100MB: "max-size":100.
You can increase this value directly here, but it's recommended to create your own "user" config file to avoid an overwrite during a f3d update, please refer to https://f3d.app/doc/user/CONFIGURATION_FILE.html

Yes, but the new latest, doesn’t give any thumbnails

Is it expected @mwestphal?

from f3d.

|| Yes, but the new latest, doesn’t give any thumbnails

Definitely not, but we will need actual version numbers from @jeedee23 to move forward. Testing the last nightly on windows would also be a start.

I don't have enough space in my work comp.
But I tried with one folder, same issue.
I updated to Windows 11, version 23H2. Now, new files downloaded from SharePoint locally do not want to display thumbnails, but files I had downloaded still have thumbnails.

F3D-2.2.1-95-g2f95ee3-Windows-x86_64 is the version I use. The only one giving thumbnails for step files, but not for all of them (even if size < 100MB) and it shows the pop-up

I now use onedrive on a small server, and use viceversa pro to sync all other computers with the files I want. They become local, so thumbnails (not all) are generated, less bandwidth also.

This is an old thread and this option is not present anymore.

from f3d.

I just tested the last nightly and thumbnails are working fine (outside of onedrive which I do not use).

@Meakk did you actually try with onedrive ?

from f3d.

Yes it is a onedrive issue, other apps have the same problem. The files are not stored the usual way, I think there is need for a MS api to be able to do this

@Meakk did you actually try with onedrive ?

No I don't have a onedrive account

from f3d.

You have to sync differently with onedrive.

Ok, looks like we do need to do something else to support onedrive file. Which we will probably not do for now I'm afraid.

Yes, that is what I thought, because it is almost impossible.
