Why are thumbnails not updated?

Hello,

the thumbnails are not updated when a new image is added to the folder being displayed. I have checked the settings but could not find anything related to that. Am I missing something?

I display only the TIF images. Could it be that the large number of jpgs in this folder (>1000) is slowing down the process?

I would guess you need to refresh the view, usually that is F5, not sure though.

Double click on the folder in RT file browser should show the new files.

Yes, of course, that is what I am doing. But I had thought, the view should be updated automatically once a new image is added. Am I wrong about this?

RT scans periodically (let’s say every 5 seconds) for new images in the current folder. If the image is still not completely written, if fails reading it.

In fact, it is not updated after 15 minutes!

Even after double-click on the folder?

Does it scan every 5 seconds?
Doesn’t this affect performance?
If I am processing an image and every 5 seconds it has to check for a new image … what a waste of time!

This operation is inexpensive in modern OSs, see for example inotify(7) - Linux manual page

thanks @mbs
So it is not relevant.

I did not double click since I thought this will be done automatically.

Would you be so graceful to try if double click works?

Jossie · January 17, 2021, 8:21pm

See my second post above. This is what I am doing right now…
