Can one add custom properties to NTFS folders?

问题

I would like to be able to add my own custom data/properties to existing folders on NTFS, so that if a folder is moved, the properties move with it. One solution would be to store a file within the folder to contain whatever I need or want.

What I am particularly interested in, is whether or not there is a way to add custom properties to the directory file system object itself.

回答1:

If you are feeling brave (~~or foolish~~) perhaps an Alternative Data Stream would be an alternative.

I am not sure if can be applied to a directory as opposed to a normal file and it's littered with concerns that need to be considered:

There are no standard windows user tool that lists them (e.g. can't view from explorer or cmd prompt, but can be opened in most programs given correct name).
They will not transfer off of the NTFS filesystem well.
They may also raise some AV flags, I do not know.

Happy coding.

Here is a way in c# to show file custom properties

DSOFile.OleDocumentPropertiesClass file = new DSOFile.OleDocumentPropertiesClass();

file.Open(@"C:\setup.exe", false, DSOFile.dsoFileOpenOptions.dsoOptionDefault);

string key = "key1";

object value = "value1";

// Adds new custom property.

file.CustomProperties.Add(key, ref value);

// Go through existing custom properties.

foreach (DSOFile.CustomProperty p in file.CustomProperties)

{
Console.WriteLine("{0}:{1}", p.Name, p.get_Value().ToString());
}

file.Close(true);

First in file.CustomProperties.Add(key, ref value); by modifying the attribute key(the property, you can modify it, here are the following. in key you should put one of the following attribute_names, that are here described as constants by names from their real values

Const FILE_ATTRIBUTE_READONLY = 1
Const FILE_ATTRIBUTE_HIDDEN = 2
Const FILE_ATTRIBUTE_SYSTEM = 4
Const FILE_ATTRIBUTE_DIRECTORY = &H10
Const FILE_ATTRIBUTE_ARCHIVE = &H20
Const FILE_ATTRIBUTE_ENCRYPTED = &H40
Const FILE_ATTRIBUTE_NORMAL = &H80
Const FILE_ATTRIBUTE_TEMPORARY = &H100
Const FILE_ATTRIBUTE_SPARSE_FILE = &H200
Const FILE_ATTRIBUTE_REPARSE_POINT = &H400
Const FILE_ATTRIBUTE_COMPRESSED = &H800
Const FILE_ATTRIBUTE_OFFLINE = &H1000
Const FILE_ATTRIBUTE_NOT_CONTENT_INDEXED = &H2000

Then you should assign the desired value to the constant, in value

Then to see each properties of each file it show them on the line

Console.WriteLine("{0}:{1}", p.Name, p.get_Value().ToString());
