什么是文件中转站？
文件中转站是一个跨设备文件与文本临时传递工具。当你需要将手机上的文件传到电脑，或者将电脑上的一段文本分享给平板时，无需安装任何软件或登录任何账号，只需三步即可完成：
- 发送：在一台设备上上传文件或输入文本，系统生成一个6位数字编号和对应的二维码。
- 分享：将编号告诉对方，或让对方扫描二维码。
- 接收：在另一台设备上输入编号或扫码，即可下载文件或取回文本。
安全与隐私
所有数据存储在 Cloudflare KV 中，采用全球分布式 CDN 基础设施，传输过程全链路 HTTPS 加密。数据在提交后 24 小时自动清除，也可在取回后手动提前删除。6位编号采用随机生成，碰撞检测确保唯一性。
使用场景
- 手机拍照后快速传到电脑编辑
- 将电脑上的配置文本推送到服务器
- 在没有微信/QQ 的设备间传递文件
- 临时分享一段代码或文本给同事
- 跨操作系统传文件（如 Linux ↔ Windows ↔ macOS）
限制说明
单次上传文件最大 50MB，文本最大 10MB。大文件自动分片存储，取回时透明拼接还原。6位编号的随机空间为 100 万个组合，同时在线的中转数据量过大时可能出现编号冲突（系统会自动重试生成）。24小时过期时间不可延长，请在有效期内取回数据。
What is Transfer Station?
Transfer Station is a cross-device temporary file and text sharing tool. When you need to send a file from your phone to your computer, or share text from your PC to your tablet—no software install or login required—just three steps:
- Send: Upload a file or enter text on one device. The system generates a 6-digit code and a QR code.
- Share: Tell the recipient the code, or have them scan the QR code.
- Receive: On the other device, enter the code or scan the QR code to download the file or retrieve the text.
Security & Privacy
All data is stored in Cloudflare KV on a globally distributed CDN infrastructure, with full HTTPS encryption. Data is automatically deleted after 24 hours, or you can manually delete it after retrieval. The 6-digit code is randomly generated with collision detection to ensure uniqueness.
Use Cases
- Quickly transfer a photo from phone to computer for editing
- Push config text from your PC to a server
- Transfer files between devices without WeChat/QQ
- Temporarily share code or text with a colleague
- Cross-OS file transfer (Linux ↔ Windows ↔ macOS)
Limitations
Maximum file size per upload is 50MB; text is limited to 10MB. Large files are automatically split into chunks and transparently reassembled on retrieval. The 6-digit code has 1 million possible combinations. If concurrent transfers are extremely high, code collisions may occur (the system auto-retries generation). The 24-hour expiry cannot be extended—please retrieve your data before it expires.
