超大附件‌是指那些文件体积较大的附件，通常用于上传大文件，如视频、音频、大型文档等。由于这些文件体积大，普通的上传方式可能会导致上传时间过长或容易中断，因此需要特殊的处理方式。超大附件的上传通常采用分片上传和断点续传技术来优化用户体验。和快速的文件上传体验。

Oversized attachments refer to attachments with large file sizes, typically used for uploading large files such as videos, audios, large documents, etc. Due to the large size of these files, ordinary upload methods may result in long upload times or easy interruptions, thus requiring special handling methods. The upload of oversized attachments usually uses shard upload and breakpoint resume techniques to optimize the user experience. And fast file upload experience

‌断点续传‌是一种技术，允许在文件上传或下载过程中，如果遇到网络中断或其他问题导致传输中断，用户可以从中断的地方继续传输，而不是从头开始。断点续传通过将文件分割成多个小块进行上传，如果上传过程中断，下次可以继续从上次中断的地方开始上传，而不是重新上传整个文件。这种技术可以有效减少上传时间，提高用户体验。 

Discontinuous transmission is a technique that allows users to resume transmission from the point of interruption during file upload or download, rather than starting from scratch, in the event of a network interruption or other issues causing the transmission to be interrupted. Discontinued upload divides the file into multiple small pieces for uploading. If the upload process is interrupted, the next upload can start from the last interrupted place instead of re uploading the entire file. This technology can effectively reduce upload time and improve user experience.

拖拽上传‌是一种用户友好的文件上传方式，允许用户通过拖拽操作将文件直接从本地拖放到网页上的指定区域进行上传。这种方式简化了上传流程，提高了操作的便捷性和用户体验。拖拽上传通常与现代Web应用结合使用，提供更直观和快速的文件上传体验。
