The MOSDAL folder, stored in the user's My Documents folder, organizes captured log data by component, allowing users to locate and begin troubleshooting efficiently. All captured data is formatted in plain text, making it simple to review information for a specific area of troubleshooting.

MOSDAL is designed to provide a broad picture of the user’s system, providing them with the information needed  to perform the next step in resolving their issue. MOSDAL’s folders and the data collected include:
