Yes, it's possible but it depends on what you need. You might need to set up an HTTP server yourself, which isn't straightforward. Alternatively, you could consider an SMB server like Samba, though it can be time-consuming and not plug-and-play either. There are other options too—maybe a NAS server combined with CentOS and Samba? It's a bit unclear for me.
Share the folder in Windows to generate an SMB share. Use an app such as File Manager on Android to access it.
