Hi Alex,
I see. Indeed, the default "Files" tab can't be removed from a channel in Teams. However, you can rename it to make it clearer that it's not the primary file storage location for that channel. For example, you could rename it "Chat Files" or "Temporary Files" to indicate that it's only for files that are shared in channel chat.
Another option you might consider is to set up a naming convention for files and folders that identifies the project they belong to. For example, you could prefix all files and folders related to a particular project with the project name or code. This can help ensure that files are stored in the correct location and make it easier to locate files related to a particular project.
Additionally, you can create custom views in the document library that filter files based on their properties. For example, you can create a view that shows only files related to a particular project, or only files of a certain file type. This can help make it easier to find the files you need within a large document library.
Let me know if you need further assistance.
Regards,
Joshua.
