The creation time is the time that the file 3471N/A * <p> If the file system implementation does not support a time stamp 3471N/A * to indicate the time when the file was created then this method returns 3471N/A * an implementation specific default value, typically the {@link 3471N/A * #lastModifiedTime() last-modified-time} or a {@code FileTime} 3471N/A * representing the epoch (1970-01-01T00:00:00Z). 3471N/A * @return a {@code FileTime} representing the time the file was created 893N/A * Tells whether the file is a regular file with opaque content. 893N/A * Tells whether the file is a directory. 1381N/A * Tells whether the file is a symbolic link. 893N/A * Tells whether the file is something other than a regular file, directory, 893N/A * Returns the size of the file (in bytes). The size may differ from the 893N/A * actual size on the file system due to compression, support for sparse 893N/A * files, or other reasons. The size of files that are not {@link 893N/A * #isRegularFile regular} files is implementation specific and 893N/A * therefore unspecified. 908N/A * @return the file size, in bytes 893N/A * Returns an object that uniquely identifies the given file, or {@code 893N/A * null} if a file key is not available. On some platforms or file systems 893N/A * it is possible to use an identifier, or a combination of identifiers to 893N/A * uniquely identify a file. Such identifiers are important for operations 893N/A * such as file tree traversal in file systems that support <a 893N/A * that allow a file to be an entry in more than one directory. On UNIX file 893N/A * systems, for example, the <em>device ID</em> and <em>inode</em> are 893N/A * commonly used for such purposes. 893N/A * <p> The file key returned by this method can only be guaranteed to be 893N/A * unique if the file system and files remain static. Whether a file system 893N/A * re-uses identifiers after a file is deleted is implementation dependent and 893N/A * therefore unspecified. 893N/A * <p> File keys returned by this method can be compared for equality and are 893N/A * suitable for use in collections. If the file system and files remain static, 3471N/A * and two files are the {@link java.nio.file.Files#isSameFile same} with 893N/A * non-{@code null} file keys, then their file keys are equal. 893N/A * @see java.nio.file.Files#walkFileTree
