Odd behavior with file naming on RT-AC3100 using the USB file sharing (Samba)

[Robert Giuffre]

So this is more of an annoyance than a bug. I have an ASUS RT-AC3100 with the latest Merlin firmware. I have a 4TB SSD connected to the front USB 3.x port on the router. I am using File Sharing (SAMBA) as a Media Server. It works great on my network. The only issue I am having is when I create a new folder in the webui on the router. If I type the folder name in upper and lower case, it shows correctly on the media players. But, if I type something in all upper-case, it shows in lower-case on the media players. For example, I have the series MASH. I've tried many different combinations to try and get it all in upper-case. I've tried naming the folder "M.A.S.H." but it shows as "m.a.s.h." I tried naming the folder "MASH", but it shows as "mash". But if I name the folder "Mash", then it shows as "Mash".

I'm curious why the router would force it to all lower-case, unless it's a mixture of upper and lower case.

This is a feature of Windows File Explorer and nothing to do with Samba or the router.

Windows File Explorer displays shared folder names with all uppercase letters as all lowercase letters. What can I do? - Synology Knowledge Center

See the Ubuntu example below which has no problem displaying upper, mixed and lower case names.
