## Class IgfsPath

- java.lang.Object
- - org.apache.ignite.igfs.IgfsPath

All Implemented Interfaces:
  Externalizable, Serializable, Comparable<IgfsPath>, Binarylizable

    public final class IgfsPath
    extends Object
    implements Comparable<IgfsPath>, Externalizable, Binarylizable

`IGFS` path to file in the file system. For example, to get information about a file you would use the following code:

         IgfsPath dirPath = new IgfsPath("/my/working/dir");
         IgfsPath filePath = new IgfsPath(dirPath, "file.txt");

         // Get metadata about file.
         IgfsFile file = igfs.info(filePath);
