# Directory
> A directory on a []'s filesystem.
A directory on a \[`Machine`]'s filesystem.
Obtain via \[`Machine.dir`] or \[`Machine.tempDir`]. The handle stays
bound to the machine it came from: paths are meaningful only on that
machine, and all operations run there.
## Constructor
```typescript
Directory(): Directory
```
### Returns
`Directory`
## Methods
### copyTo()
```typescript
copyTo(dest: string): Directory
```
Copies the directory recursively to `dest` on the same machine,
returning a handle to the copy. Fails when `dest` already exists.
Local: an absolute `dest` is used as-is. A relative `dest` is joined
to the `SimularFiles` root (`..` is kept — this is a default base,
not a sandbox).
Android: `dest` must be absolute.
#### Parameters
#### Returns
`Directory`
### delete()
```typescript
delete(): void
```
Deletes the directory and everything in it, invalidating the handle.
### isReadonly()
```typescript
isReadonly(): boolean
```
Whether the directory is read-only.
#### Returns
`boolean`
### listDirs()
```typescript
listDirs(): Directory[]
```
All subdirectories of this directory (non-recursive), hidden ones
included.
#### Returns
`Directory[]`
### listFiles()
```typescript
listFiles(): File[]
```
All files in this directory (non-recursive), hidden files included.
#### Returns
`File[]`
### modified()
```typescript
modified(): number
```
The last modification time of the directory itself as milliseconds
since the Unix epoch.
#### Returns
`number`
### moveTo()
```typescript
moveTo(dest: string): void
```
Moves the directory to `dest` on the same machine. Fails when
`dest` already exists. Path resolution as in \[`Directory.copyTo`].
#### Parameters
### name()
```typescript
name(): string
```
The directory name (last component of the path).
#### Returns
`string`
### path()
```typescript
path(): string
```
The directory's path on its machine, as a string.
#### Returns
`string`
### rename()
```typescript
rename(newName: string): void
```
Renames the directory in place (same parent directory). `newName`
must be a single filename component.
#### Parameters
