What is a .PAR file?

A PAR file is an aircraft parameters file used by FMS (Flying-Model-Simulator), a flight simulation game for Windows. It saves the airplane geometry and physics properties such as mass, center of gravity, and inertia moments. PAR files are used for creating custom aircraft to fly in the game.

What Are Common Causes of ".PAR" Files Lost or Failure?

There are several common causes of ".PAR" files lost or failure:

  1. File corruption: If the ".PAR" file becomes corrupted due to disk errors, software glitches, or other issues, it may result in loss or failure.
  2. Incomplete or interrupted downloads: If the ".PAR" file download process is interrupted or not completed successfully, it may lead to missing or incomplete files.
  3. File deletion: Accidental deletion of the ".PAR" file or its associated files can cause loss or failure.
  4. Disk or storage device failure: If the disk or storage device containing the ".PAR" files fails or becomes inaccessible, it can result in loss or failure.
  5. Virus or malware attacks: If the ".PAR" files are infected by viruses or malware, they may become corrupted or deleted, leading to loss or failure.
  6. Software or hardware conflicts: Compatibility issues between the software used to create or extract ".PAR" files and the system hardware or operating system can cause failure or loss.
  7. User error: Mistakes made by the user, such as improper handling of files, incorrect settings, or accidental formatting of storage devices, can result in ".PAR" file loss or failure.

It is important to regularly back up ".PAR" files and take necessary precautions to prevent data loss or failure.

How to recover lost ".PAR" files?

Sometimes while working with a computer, laptop or other stationary or mobile devices, you may encounter various bugs, freezes, hardware or software failures, even in spite of regular updates and junk cleaning. As a result, an important ".PAR" file may be deleted.

Questions and answers

  • What is the purpose of a .PAR recovery file?

    A .PAR recovery file, also known as a parity file, is used for error detection and recovery in data storage systems. The purpose of a .PAR recovery file is to provide redundancy and protection against data loss or corruption.

    When files are stored or transferred, there is always a risk of data corruption or loss due to various factors such as transmission errors, disk failures, or accidental deletion. A .PAR recovery file is created by using a parity algorithm to generate additional data based on the original file's contents. This additional data, stored in the .PAR file, can be used to reconstruct or repair the original file in case of data loss or corruption.

    The .PAR recovery file works by calculating parity information based on the original file's data blocks. This parity information allows for the detection and correction of errors in the original file. If any part of the original file becomes corrupted or lost, the .PAR file can be used along with the remaining intact data to reconstruct the missing or damaged parts.

    In summary, the purpose of a .PAR recovery file is to provide a form of error detection and recovery mechanism, enabling the reconstruction or repair of data in case of data loss or corruption.

  • How does a .PAR recovery file work to repair corrupted or missing data?

    A .PAR recovery file, also known as a parity file, works by using a mathematical algorithm called Reed-Solomon error correction to repair corrupted or missing data. It is commonly used in situations where data needs to be protected against errors or loss, such as in file sharing or data storage systems.

    Here's how it works:

    1. Parity Calculation: When a .PAR recovery file is created, it calculates parity information based on the original data. Parity information is essentially additional data that is generated using mathematical calculations.
    2. Error Detection: When the original data is corrupted or missing, the .PAR recovery file is used to check for errors. It compares the corrupted data with the parity information to detect errors or missing parts.
    3. Error Correction: Once errors are detected, the .PAR recovery file uses the parity information to reconstruct the missing or corrupted parts of the data. It does this by applying the Reed-Solomon error correction algorithm, which uses the parity information to fill in the gaps or fix errors.
    4. Reconstruction: After the error correction process, the missing or corrupted parts of the data are reconstructed, resulting in a repaired version of the original data.

    It's important to note that the .PAR recovery file needs to have enough parity information to be able to reconstruct the missing or corrupted parts. The more parity information available, the higher the chances of successful recovery. Additionally, the size of the .PAR recovery file will depend on the amount of original data and the desired level of error protection.

  • Are there any limitations or drawbacks to using .PAR recovery files for data recovery?

    Yes, there are some limitations and drawbacks to using .PAR recovery files for data recovery:

    1. Dependency on PAR2 software: PAR recovery files require specific software (such as QuickPar or MultiPar) to perform the recovery process. This means that you need to have the appropriate software installed on your system to utilize the .PAR files.
    2. Limited file types: PAR recovery files are primarily used for recovery of data in the form of files, such as documents, images, videos, etc. They may not be suitable for recovering other types of data like system files, applications, or databases.
    3. Redundant data: PAR recovery files create redundancy by adding extra data to the original files. This redundancy can be quite large, especially when dealing with large files, resulting in increased storage requirements.
    4. Time-consuming recovery process: The process of recovering data using .PAR files can be time-consuming, especially when dealing with large files or a large number of files. The recovery process involves analyzing and reconstructing the data from the original and PAR files, which can take a significant amount of time.
    5. Limited error correction: While PAR recovery files can help recover data in case of file corruption or loss, they have limitations in terms of error correction. They can only correct errors up to a certain extent, and if the data is severely damaged or corrupted, the recovery may not be successful.
    6. Storage limitations: Storing a large number of PAR recovery files can require significant storage space, especially if you have multiple versions or revisions of the same file. This can be a drawback if you have limited storage capacity.

    Overall, while PAR recovery files can be helpful in certain scenarios, they have their limitations and may not be suitable for all types of data recovery situations. It is important to assess the specific requirements and limitations before relying solely on .PAR files for data recovery.
