## File name

Usually, the file name is *not* `measurements.zip` but instead something like `bb2241039-2026-01-09.zip` that includes both the ID if your device (`bb2241039`) and the current date (`2026-01-09`).

### Don't confuse *measurements.zip* with DDB

Both the [device data bundle](/software/file-formats/device-data-bundle-ddb.md) and the *measurements.zip* file uses a file name in the `bb2241039-2026-01-09.zip` format. It is easy to confuse the two but their purpose is very different.
{% endhint %}

## Contents

Contains a single folder called `measurements` . Within this folder you find a [BDR file](/software/file-formats/bdr-file.md) for each *Measure*-like program started on your device. Example:

* `measure-bb2241039-2026-01-08T134344+0100-R98.bdr`
* `measure-bb2241039-2026-01-08T153547+0100-R99.bdr`
* `measure-bb2241039-2026-01-08T154559+0100-S00.bdr`
* `measure-bb2241039-2026-01-08T154954+0100-S01.bdr`
* `measure-bb2241039-2026-01-08T155239+0100-S02.bdr`

The file name includes:

* Device ID (`bb2241039`)
* When the measurement started in the ISO 8601 format including the UTC offset (`2026-01-08T155239+0100`)
* The mnemonic measurement ID (`S02`)

## ZIP format

The *measurements.zip* file uses the [ZIP file format](https://en.wikipedia.org/wiki/ZIP_\(file_format\)). Modern operating systems such as Microsoft Windows has built-in support for ZIP files and readily opens these files.
