# Viewing files in Config File Manager

## Viewing startup and running configuration files

OpUtils automatically downloads the startup and running configuration files when a cisco device is added to the Config File Manager tool. To view these configuration files, please follow the steps given below.

1. Click on **Networking Tools** and select **Config File Manager.**
2. In the list of managed devices, in the row of the device whose configuration file you wish to view, under the **Config_Files** column, click on the startup or running configuration files icon.
3. This displays the configuration file of the specific device.

## Comparing configuration files

Config File Manager enables you to compare any two configuration files that are downloaded using OpUtils. This capability helps you compare and understand the configurations applied to different cisco devices in your network.

To compare configuration files,

1. Goto **Config File Manager** under **Networking Tools**.
2. In the **Actions** tab click on the **Compare** icon.
3. Select the **device**, **Configuration Type**, and **Config Files** you wish to compare under the **LHS** and **RHS** input fields.

OpUtils displays the comparison side by side and also highlights the changes between the configuration files with color codes that indicate lines that were added, deleted, or modified.
