Re: Why does the Uppercase Letters of my file name change to lower case

Hi there dummy, I hope you're well today!

I moved your post here so that I can ask you to check out Lusil's detailed post above on why this is occurring and how you can force the change in folder names. 

Let me know if this helps!

No this does not help Daphne  since I'm not using a Server.

Also it's not ONLY about Case sensitive, it's about renaming a folder called

''polo 9994'' to ''9994'' for example.
You could have seen this in the pictures I showed in my topic.

And it won't show this change on the other computer.
When I do it on this other computer, and look at this computer, same issue.

I opt to move my topic to stand-alone , since this ain't related. Thank you.

Thanks for getting back to me here dummy!

I wasn't able to open the links unfortunately on my side, would you mind sending them as a shared link instead?

As you mentioned changing the folder name to show with a different case, it seemed that it would be related to this topic. 

When renaming a file/folder and changing only the case of the name, it's related to the OS being Windows or Mac rather than a server, what Lusil mentioned about servers isn't related to this action.

Since you mentioned that you're changing the name fully, can you check if you see the name change made in your account online?

If you see the change online, then please let me know the sync status of the unchanged device. If you don't see the name change, then please check the sync status of the device you made the change on.

Let me know what you find!

I found the culprit. 
It seems Windows 10 Search function lets you Rename a Folder...
However it will not show the renamed folder directly (as shown in video), even not after hitting F5 to Refresh.
When I open the Folder again, it does show the changed Foldername.
...But it won't show on the Other PC.

See video demo: https://youtu.be/Qn8kvZfGmAo

Even worse: after this event happened, you can change the folder ''the normal way/without using search'' but it won't change any longer.
Sure on this PC, it shows the change, but not on the other.
So it looks like the folder is affected due using Search and then alter the name, which makes it unchangeable, atleast, on the other PC to show.

See video #2: https://youtu.be/398nJL8Gf2M

Is this some Windows 10 function, that needs to be altered?
So that it will directly change foldername?

Thanks for the videos dummy!

When you rename the folder from the search, it doesn't change the actual name of the folder, it just appears to do so. You can check out more info on this process here.

You should be able to just delete the desktop.ini file to revert the file name back to the actual name and allow you to change it correctly.

Since the folder isn't actually renamed, Dropbox isn't able to push the rename to your account and other devices. In this case, I can only advise against renaming from the search results.

Let me know if that does the trick!
