Can be literally anything. aspen does not use this data in any way or shape.

This object will set initial metadata.

Additional metadata can be added using FileEntry#addMetadata (existing metadata can be updated using same method).

You can get the value of key using FileEntry#getMetadata. And can be removed using FileEntry#removeMetadata

You can use Root#onDidChangeMetadata hook to get notified whenever a FileEntry's metadata is changed, added or removed.

Examples:

• Your own state tracking systems
• Your own event management stuff
• ctime, mtime, size, you name it

If a path is given, it'll work fine as the basename will be extracted automatically

Avoid hardcoding the numerical value, instead, use the FileType enum to select either File or Directory
