# Providing Windows crash dump file

If you experience OmniScope crashes on Windows platform, please go to:

Options -> Open Logs

In the explorer folder that opens please find a file with **\*.dmp** extension. It's a crash dump file that we can use to investigate the crash - please provide the file so that we can provide the fix.

If the application crashes on startup and it's impossible to access the Open Logs option, please find the crash dump file in this directory:

```
C:\Users\USERNAME\AppData\Local\NobeOmniScope
```

## Full Memory Dump (Windows)

By default OmniScope writes a **mini dump** — a compact snapshot that covers the crashed thread and key module info. If you are asked by support to provide more detail, you can enable a **full memory dump** in Preferences:

**Preferences → Crash Diagnostics → Full memory dump**

With this option on, the next crash will produce a much larger `.dmp` file that includes all thread stacks, handle data, and loaded code segments. This is helpful when a mini dump does not contain enough context to reproduce the issue.

{% hint style="warning" %}
Full memory dumps can be several hundred MB in size. Only enable this when asked by support and disable it again once the dump has been collected.
{% endhint %}
