I have seen other comments about this in community posts and "solutions" for how to ignore files in dropbox. The solution, however, is not ideal and tedious to manage across multiple devices. I would like to see dropbox create a .dropboxingore functionality, similar to how a .gitignore or .dockerignore file works. This would allow my ignore rules to sync across devices so I don't have to think about it. Additionally, it will save time by allowing users to add a .dropboxignore file in the root of their dropbox directory to always ingore directories such as python virtual environments or node_modules.
An added functionality that would be nice would allow the ignore file to be able to source other files to prevent having to create multiple ignore files. Below is an example of a potential ".dropboxignore" file that would support typical ignore syntax but also have the ability to include ignore rules from other filetypes. This example would ignore all rules in .gitignore files as well as .envrc or .venv files in the current directory and all below.
