File naming in SharePoint

If we add another content type (such as the infopath form) to the created document library, a problem occurs when the file name is created based on the form: the system will automatically overwrite the existing file (by default, you choose to overwrite the existing file when saving the file, obviously it is impossible for you to choose not to overwrite the existing file every time you save the file ), this is a very dangerous operation.
There is still no good solution for finding a lot of materials. I tried to directly save the file in the form on the client, but the infopath form of Forms Services does not support this function, finally, I decided to try the workflow.
1. Create a workflow and create a list project in Sharepoint. When a new project exists in the document library, the file name of the current project is automatically added to the newly created list project.

2. Determine whether the project is the same as the existing project in the list project based on the file life.

I don't know if that prawn has a better solution. Can I take it out and study it together.
