It’s deleted now but I definitely recall them asking about compatibility across different operating systems and filesystems. And as long as you stick to Windows’ restrictive naming scheme, your filenames will be compatible with everything.
But you don’t understand! My question is actually unique! I would know that, because none of the 0 other posts I read mention my incredibly specific and niche use case that I developed because I don’t understand the fundamentals!
I don’t think any of your rules actually have anything to do with compatibility between operating systems.
As long as the filename doesn’t contain <, , :, ", /, \, |, ?, or * then it can exist on any operating system.
If you’re going to use the file creation time as the filename, just adhere to ISO 8601 with precision to the millisecond. If you’re creating multiple image/video files at the same millisecond, your engineering staff can solve that problem for you.
Instead of using keywords, have you heard of this thing called a folder? It’s great for organizing arbitrary files!
