It's been 17 years since Box came online. Isn't it about time stop nagging about Mac's .icon invisible files when we upload a custom folder?
Or at least NOT stop the uploading process just to nag me about that?
It's metadata.
Along with .TS_FOLDER they're part of the system. The end user has no control over that.
Please either offer support for .icon or ignore it.
Just don't keep nag about it for the next 17 years. Please.
