如何创建指向存储在Internet /云中但在Windows资源管理器中显示为“本地文件”的文件的链接？

[英]How to create a link to a file stored in internet / cloud but appears as a 'local file' in Windows Explorer?

Similar to OneDrive's "Files On-Demand" as well as DropBox's "Smart Sync" functionality, I am curious how to create a file that appears to be on local disk normally but is actually linked / stored in the internet or cloud. 与OneDrive的“按需文件”以及DropBox的“智能同步”功能相似，我很好奇如何创建一个看上去通常位于本地磁盘上但实际上已链接/存储在Internet或云中的文件。

I think this is different from .lnk or .url files as they retain the following even if they are stored on the cloud: 我认为这与.lnk或.url文件不同，因为即使它们存储在云中，它们也保留以下内容：

filetype (.pdf, .xlsx, etc.) 文件类型（.pdf，.xlsx等）
location on disk (eg folder path) 磁盘上的位置（例如文件夹路径）
size (original file size though size on disk is 0 ) 大小（尽管磁盘大小为0，但原始文件大小）
file icon 文件图标

Is there another type of file or any metadata that tells Explorer that a particular file should be retrieved from the internet when it is accessed? 是否存在另一种类型的文件或任何元数据，告诉资源管理器在访问特定文件时应从互联网上检索该文件？

I don't know how the others do it but if I was creating something like this I'd have my client program create the dummy 0 size files with a unique extension that I have registered to my program then when the user double clicks on it, window will try to open the file with my program and I read the file name and do the work to download the file to some temp folder so the user can view it. 我不知道其他人是怎么做的，但是如果我正在创建类似的东西，我会让我的客户端程序创建一个虚拟的0大小的文件，该文件具有我已经注册到程序中的唯一扩展名，然后当用户双击它时，窗口将尝试使用我的程序打开文件，然后我读取文件名，并进行工作以将文件下载到某个临时文件夹中，以便用户查看。

Further you could monitor the temp folder so that if the user saves any changes you could upload those changes to your cloud location. 此外，您可以监视temp文件夹，以便如果用户保存任何更改，则可以将这些更改上载到您的云位置。
