How to retrieve the number of files in a folder using a custom property

Purpose

This article explains how to retrieve the count of files within a specified folder using a script and display the count as a custom property in the SureMDM console. Using this approach allows administrators to monitor file counts remotely without requiring manual access to the device.

Prerequisites

• Administrator access to the SureMDM Console
• The target device must be enrolled in SureMDM and actively online
• The target folder path must exist on the device.
• Device must be online and connected periodically to sync the custom property

Steps

1. Log in to the SureMDM console
2. Create a custom device property in account settings with the below script

function assignValue(){
var result= suremdmjs.listFiles("/sdcard/Documents");
var list = JSON.parse(result);  // here list will be JSON Array
 return list.length.toString();
}

3. Assign the created property to a subgroup
4. Once the device property is synced
5. Verify the value in the device properties of the devices present in the group

Conclusion

By configuring a custom property with the appropriate script, administrators can efficiently retrieve and monitor the number of files within a specified folder directly from the SureMDM console. This method eliminates the need for manual device access, improves visibility across managed devices, and enables quicker decision-making based on real-time file data.
