+
+// Load the folder info with sub folders and with file contents.
+await existent.load({ withSub: true, withContent: true })  👈
+
+// Create and load the folder info without the 
+// content (be careful when loading big files).
+nonExistent.loadSync() 👈

+  withSub: true,    👈
+  withContent: true 👈
+})
+```
+
+When copying the folder you can set the `mockedValues` to `true` to copy the 
+files with fake names:
+
+```typescript
+import { Folder } from '@athenna/common'
+
+const copiedFolder = await folder.copy(Path.storage('copy-of-file'), {
+  mockedValues: true 👈
+})
+```
+
+#### `Folder.move()` & `Folder.moveSync()` 
+
+Move the folder to other location:
+
+```typescript
+import { Folder } from '@athenna/common'
+
+const movedFolder = folder.moveSync('./move-of-folder')               👈
+const movedFolder = await folder.move(Path.storage('move-of-folder')) 👈
+```
+
+To move the folder and load the sub folders and the content of the 
+move set the `withSub` and `withContent` as `true`:
+
+```typescript
+import { Folder } from '@athenna/common'

+
+const movedFolder = await folder.move(Path.storage('file-path'), {
+  mockedValues: true 👈
+})
+```
+
+#### `Folder.remove()` & `Folder.removeSync()` 
+
