Looks like exposing all of these might help with UI/UX for users on media add flow to stop problems before they start ?

/// The maximum length we allow a filename to be. When combined
/// with the rest of the path, the full path needs to be under ~240 chars
/// on some platforms, and some filesystems like eCryptFS will increase
/// the length of the filename.
pub static MAX_MEDIA_FILENAME_LENGTH: usize = 120;


// We can't enforce the 120 limit until all clients have shifted over to the
// Rust codebase.
pub const MAX_MEDIA_FILENAME_LENGTH_SERVER: usize = 255;


/// Media syncing does not support files over 100MiB.
pub static MAX_INDIVIDUAL_MEDIA_FILE_SIZE: usize = 100 * 1024 * 1024;
