What is a PLW file?

PLW files mostly belong to PicoLog for Windows. PLW files are created by PicoLog for Windows to record sensor data from Pico Technology's data loggers. They use an internal binary format that efficiently organizes measurement data.
If you have a PLW file, it contains logged information captured during experiments or testing sessions. The file stores data in a structured way that only the PicoLog software can read directly.
Here are some key points summarized by FilExt.com:

• Data Capture: Designed to record continuous sensor measurements.
• Binary Format: Optimized for performance and efficient storage.
• PicoLog Integration: Managed by PicoLog for Windows, which offers viewing and conversion options.

FilExt.com tip: Additional details can be found at Pico Technology's website.

How to open a PLW file

You need a suitable software like PicoLog for Windows to open a PLW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PLW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PLW file directly in the browser:.

PLW file extension format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the PLW files looks like this:

The PLW file extension is rather rarely used and mainly uses a special format. However, the following two file formats are common:

• 80% of all PLW files have the same signature 94 06 50 69 63 6F 4C 6F 67 20 66 6F 72 20 57 69. They consist of illegible, cryptic characters. The files are 20 KB to 350 KB in size, with a median of 41 KB. The file type was developed 10 years ago and is still in use today. The files contain the following words: PicoLog for Windows. These files are attributed to data, group, temperature, sphere, noname, cube, temp, smallest, brass, cycle, inner and cure.

All other PLW files (20%) have no consistent format. Sometimes used for writer or line. If you want to find out what your PLW file contains, drag and drop it onto this page.
