Ask for the implementation of the file delete

[ZhangHuan0407]

Hi all.
I like to type code, I'm currently learning how to make a network disk for myself.

During a simple debugging process, I found that the following steps exist for "Delete files under a folder"

Through the logs, guess the call order:
FindFilesWithPattern(“\linux-x64\sv", “\linux-x64\sv\DokanNet.resources.dll”, out files, ref DokanFileInfo info);
CreateFile(“\linux-x64\sv\DokanNet.resources.dll”, DokanNet.FileAccess.Delete, FileShare.Delete, FileMode.Open, FileOptions.None, FileAttributes.None, ref DokanFileInfo info);
GetFileInformation(“\linux-x64\sv\DokanNet.resources.dll”);
Cleanup(“\linux-x64\sv\DokanNet.resources.dll”, ref DokanFileInfo info); // with DeletePending symbol

My question is:

1. The CreateFile interface looks like "get file symbol" instead of "create file"?

2. I don't see DeleteFile being called, my understanding is:
   if (DeleteFile(filePath) == DokanResult.Success)
   Cleanup(filePath)
   But in reality Dokan doesn't work like this?

It all depends on how applications call it. Either they call CreateFile with FILE_FLAG_DELETE_ON_CLOSE specified and then call CloseHandle, or they call DeleteFile which internally calls CreateFile, DeleteFile and CloseHandle.

And yes, CreateFile is used to both create new files and open existing files and directories.
