# Trusted Applications
The **Trusted Applications** section defines which applications can open, edit, and save protected files. Only approved applications can access or modify protected content. PROTECT can encrypt files when users save or export them in different formats.
### Add an Application
1. Navigate to **PROTECT > Protection Scope > Trusted Application**. The page displays the list of registered applications and allows adding or editing applications.
2. Click **+New Application**.
3. In **Executable Name**, enter the executable filename, such as `winword.exe` or `acad.exe`, for the application you want to register. This defines which program is authorised to access encrypted files.
4. In **Application Suite**, specify the suite or category that the application belongs to, such as *Microsoft Office*, *Adobe*, or *AutoCAD*. This helps group related applications for easier management.
5. In **Folder Path**, enter the path substring if the executable resides in a specific location, such as `C:\Program Files\Microsoft Office`.
Click **+** to add the folder path to the selected paths list. The selected paths appear under **Folder Path Selected** on the right.
6. In **Extensions that are encrypted/decrypted**, define which file types the application can encrypt and decrypt securely. Choose one of the following options:
1. **All Extensions**
The application can encrypt or decrypt all files regardless of their extension.
2. **All but these extensions**
The application can encrypt or decrypt all files **except** those with the specified extensions.
For example, if you enter `.docx` and `.cad`, the application can encrypt or decrypt all other file types.
3. **Only these extensions**
The application can encrypt or decrypt only the file types listed here.
For example, if you add `.docx`, `.xls`, and `.ppt`, the application can encrypt or decrypt only these extensions.
Click **+** to add each extension to the list.
7. Enable **Network Drive Support** if the application needs to access encrypted files stored on network drives (shared folders or mapped drives).
8. Enable **Encrypt On Download** to encrypt files when users save or export them.
9. Click **Save**.
The application will appear in the **Application List** and will be allowed to encrypt or decrypt files securely based on your configuration.
### Edit an Application
1. Navigate to **PROTECT > Protection Scope > Trusted Application**.
2. Search for the application to edit and click the **Edit** icon in the **ACTIONS** column.
3. Update the necessary information and click **Save**.
### Delete an Application
1. Navigate to **PROTECT > Protection Scope > Trusted Application**.
2. Search for the application to delete and click the **Delete** icon in the **ACTIONS** column.
3. Click **Delete** in the Confirmation Alert.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.guardware.com/documentation/protect/protection-scope/trusted-applications.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
