This error, often accompanied by a detailed traceback, can be a roadblock for players looking to back up, modify, or share their game progress. This article dives deep into the common causes behind this error, specifically the not a compressed Palworld save, found b'PlM' instead of b'PlZ' message, and provides a comprehensive guide to troubleshooting and resolving it. Let's get your Palworld save back on track.

Understanding the Error Message: "Not a Compressed Palworld Save"

When delving into the world of Palworld and attempting to manage your saved game data, encountering an error message can be a frustrating experience. A common issue that players face is the dreaded "not a compressed Palworld save, found b'PlM' instead of b'PlZ'" error. This error message, often accompanied by a detailed traceback, indicates a problem with the file format of your save data. In essence, the system is expecting a compressed save file (identified by the 'PlZ' header) but instead finds an uncompressed or incorrectly formatted file (identified by the 'PlM' header). This discrepancy prevents the save file from being processed correctly, leading to the error. Let's break down the key components of this error and understand what they mean for your Palworld save.

Key Components of the Error

  • "Not a compressed Palworld save": This part of the message clearly states that the system was expecting a compressed save file. Palworld, like many modern games, uses compression to reduce the size of save files, making them easier to store and transfer. This compression is a crucial step in the saving process, and if it's missing, the file cannot be read correctly.
  • "Found b'PlM' instead of b'PlZ'": This is the heart of the error message. The b'PlM' and b'PlZ' are byte signatures, short sequences of bytes that act as identifiers or "magic numbers" for the file format. In this case, b'PlZ' signifies a compressed Palworld save file, while b'PlM' indicates an uncompressed or potentially corrupted file. When the system encounters b'PlM' instead of the expected b'PlZ', it knows that the file is not in the correct format.

What Does This Mean for Your Save File?

This error typically means that the save file you are trying to process is either:

  1. Not a Palworld Save File: You might have accidentally selected a file that is not a Palworld save, or it's a file from a different game or application.
  2. Corrupted: The save file might have been corrupted during the saving process, transfer, or storage. Corruption can occur due to various reasons, such as power outages, software glitches, or hardware failures.
  3. An Incorrectly Modified Save File: If you've attempted to manually modify the save file without using the proper tools or methods, you might have inadvertently changed the file format, leading to this error.
  4. An Older Version of the Save: It's possible that the save file is from an older version of the game or a different platform, and it's not compatible with the current tools or software you're using.

The Importance of Understanding the Traceback

Accompanying the error message is often a traceback, a detailed log of the steps the system took leading up to the error. The traceback can seem daunting at first, but it provides valuable clues about the origin of the problem. In the example provided:
