\\?\D:\Dropbox in the file path not allowing me to open my Word documents

Dear Hannah,

Thanks for guiding me. I found something interesting. Long name (or maybe specific symbols) of folder, where word file is placed can cause this problem.

For example:

I have a word file in the following directory:

D:\Dropbox\Euro Yarns SRL\Production\Orders\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5,Berber,Grey,Turquoise, Grey v1, Brown v1\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5,Berber,Grey,Turquoise, Grey v1, Brown v1.docx

As you can see folder and file name are quite long. This file I'm not able to open in this directory.

1st thing is: I cannot rename my word file in this directory.

2nd thing: if I make folder name shorter, my word file starts to open. A shorter folder like this:

D:\Dropbox\Euro Yarns SRL\Production\Orders\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5,Berber,Grey,Turquoise, Grey v1, Brown v1.docx

3rd thing is: If I do not rename anything, but will just move my long named folder to root dropbox directory it starts to work.

D:\Dropbox\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5,Berber,Grey,Turquoise, Grey v1, Brown v1\Order 415 - Vira - 9099, 2199, 9100, 3170, 13439,Grey 60111, E76,E70,E90,5,Berber,Grey,Turquoise, Grey v1, Brown v1.docx

In the past I didn't experienced problems with long named folders, but now it happens.

Can you please create any word document in a directory same as mine and see if it happens on your side also? If there is a limit of symbols in a file path, what is the limit then?

Thank you in advance!
