使用方法
只需三步，即可从您的设备送达任何人的收件箱。
Whether you need a fast cloud file upload tool or a simple way to upload and share files online, the process takes three steps and needs no software to install.
1. 上传
拖放文件或从设备中选择。每个文件最大 5 GB，无需账号。
Drag files onto the page or pick them with the file browser. You can add several files and upload more at any time.
2. 获取链接
我们会为每个文件生成唯一的下载链接，几秒钟即可复制。
Every transfer gets its own unique, hard-to-guess link. You can copy it with one click, or leave it as it is and send it on your own terms.
3. 分享
将链接粘贴到任何地方，或直接通过 LinearFiles 发送邮件。链接 4 天后过期。
To send the link by email, enter the recipient's address, add an optional note, and LinearFiles sends it for you. Your recipient clicks the link and downloads the file directly in their browser. They do not need to create an account or install anything.
What happens behind the scenes
Your files are sent over an encrypted HTTPS connection and stored in Amazon Simple Storage Service (S3), a cloud file storage service. They are not kept on our web server's own disk, and the link is the only way to reach them.
When links expire
Every link expires 4 days after upload. After that, a background job removes the file from storage. If someone opens the link after it has expired, they see an "expired" page instead of the file.
Quick reference
- File size: up to 5 GB per file.
- Link lifetime: 4 days from upload.
- Accounts: not needed to upload or to download.
- Sharing: copy the link, or email it from LinearFiles.
Tips for sharing
- Send the link only to the people who should receive the file. Anyone with the link can download it until it expires.
- Download what you need before the 4-day window closes. After a link expires, the file is gone, so upload it again to get a new link.
- Add a short note when you email a link so the recipient knows what to expect.
