Placeholder files for Windows 10 OneDrive are not documented

[sba923]

https://docs.microsoft.com/en-us/windows/desktop/w8cookbook/placeholder-files documents placeholder files for Windows 8.0 OneDrive (somewhat).

There is no equivalent for Windows 10 OneDrive placeholder files.

Notably, the use of attribute bits (ReparsePoint, SparseFile, Offline, Pinned, Unpinned...) and of reparse point tags (IO_REPARSE_TAG_CLOUD*) is not documented.

FWIW, I've collected this data while working on PowerShell issues PowerShell/PowerShell#8315 / PowerShell/PowerShell#9461 and PR PowerShell/PowerShell#8745

@GrantMeStrength Can you please take a look at this issue?

Alexis, this one might be aligned with your Cloud Filter docs.

Windows 10 OneDrive placeholder files

@sba923, they're called "Files On-Demand" now.

[sba923]

AFAIK "Files On Demand" is the name of the Windows _product featur_e.

What I used to call "placeholders" is called "online-only files" e.g. in https://support.microsoft.com/en-us/office/save-disk-space-with-onedrive-files-on-demand-for-windows-0e6860d3-d9f3-4971-b321-7092438fb38e

Maybe all that's needed is a well-defined corpus of hyperlinked documents on the topic.

@sba923, to my knowledge, "Files On-Demand" encapsulates "Online-only files" - FOD refers to the product feature, whereas OOF refers to a specific state of the files affected by the functionality.

I concur.

But my document issue remains 😝
