+        text: Create a class that will implement TemporaryFileManager interface with it's methods.
+      - name: Setup GroupDocs.Viewer for Java to use the class

+
+[GroupDocs.Viewer](https://products.groupdocs.com/viewer/java) allows you to control a way temporary files and directories is created. Follow these steps to implement custom logic for creating temporary files and folders:
+
+1. Create a class that implements the `com.groupdocs.viewer.common.tempfiles.TemporaryFileManager` interface and its methods:
+
+{{< tabs "example1">}}
+{{< tab "Java" >}}
+```java
+class CustomTemporaryFileManager implements TemporaryFileManager {
+
+    @Override
+    public Path createTempDirectory() {
+        // Implementation
+    }
+
+    @Override
+    public Path createTempDirectory(String... pathsAsStrings) {
+        // Implementation
+    }
+
+    @Override
+    public Path createTempDirectory(Path... paths) {
+        // Implementation
+    }
+
+    @Override
+    public Path createTempFile() {
+        // Implementation
+    }
+
+    @Override
+    public Path createTempFile(String... pathsAsStrings) {
+        // Implementation
+    }
+
+    @Override
+    public Path createTempFile(Path... paths) {
+        // Implementation
+    }
+
+    @Override
+    public void delete(Path path) {
+        // Implementation
+    }
+
+    @Override
+    public void cleanup() {
+        // Implementation
+    }
+}
+```
+{{< /tab >}}
+{{< /tabs >}}
+
+2. Create an object of the class and specify it as a parameter of the `setInstance` method of `TemporaryFileManagerFactory`:
+{{< tabs "example2">}}
+{{< tab "Java" >}}
+```java
+final CustomTemporaryFileManager customTemporaryFileManager = new CustomTemporaryFileManager();
+TemporaryFileManagerFactory.setInstance(customTemporaryFileManager);
+```
+{{< /tab >}}
+{{< /tabs >}}
+   Now [GroupDocs.Viewer](https://products.groupdocs.com/viewer/java) uses this implementation for creating temporary files and directories.
+
+3. Use the implementation for your needs as follows:
+
+{{< tabs "example3">}}
+{{< tab "Java" >}}
+```java
+final TemporaryFileManager temporaryFileManager = TemporaryFileManagerFactory.getInstance();
+final Path tempFile = temporaryFileManager.createTempFile("temp.txt");
+// Do something with the file
+temporaryFileManager.delete(tempFile);
+```
+{{< /tab >}}
+{{< /tabs >}}
+
+{{< alert style="info" >}}
+
+Default implementation creates the temporary files and directories in a directory specified by the `java.io.tmpdir` property.
+
+{{< /alert >}}
