What Are Common Causes of ".123" Files Lost or Failure?

There can be several common causes for ".123" files being lost or facing failure:

  1. Accidental deletion: The most common cause is accidental deletion by the user. If a user mistakenly deletes a ".123" file, it can be difficult to recover it unless a backup is available.
  2. Software or hardware issues: Issues with software or hardware can lead to ".123" file loss or failure. This can include software crashes, system errors, or hardware malfunctions that result in data corruption or loss.
  3. File system errors: File system errors can occur due to improper system shutdown, power outages, or other system issues. These errors can corrupt ".123" files and make them inaccessible or unreadable.
  4. Virus or malware attacks: Viruses or malware can infect and damage files on a computer, including ".123" files. This can result in loss of data or the file becoming unreadable.
  5. Disk formatting or partitioning: If a disk is formatted or partitioned without taking proper backup measures, it can lead to the loss of all data on the disk, including ".123" files.
  6. Human error: Human error, such as accidental overwriting or saving changes to the wrong file, can also cause ".123" file loss or failure.
  7. Storage media failure: If the storage media where the ".123" files are stored, such as a hard drive or flash drive, fails or becomes damaged, it can result in the loss of the files.
  8. Software compatibility issues: If the software used to create or open ".123" files is not compatible with the system or has issues, it may lead to file failure or loss.

It is important to regularly backup ".123" files and take necessary precautions to prevent data loss, such as using reliable storage devices, maintaining up-to-date antivirus software, and being cautious while handling files.

Questions and answers

  • What is the file format .123, and what type of data does it typically contain?

    The file format .123 is associated with the Lotus 1-2-3 spreadsheet software, which was popular in the 1980s and early 1990s. It was developed by Lotus Software and later acquired by IBM.

    The .123 file format contains spreadsheet data, including tables, formulas, charts, and other related information. It is primarily used for storing numerical and textual data in a tabular format, similar to other spreadsheet file formats like .xls (Microsoft Excel) and .ods (OpenDocument Spreadsheet).

  • What are the possible applications or programs that can be used to open and view .123 files?

    The .123 file extension is primarily associated with the Lotus 1-2-3 spreadsheet program, which was popular in the 1980s and 1990s. However, Lotus 1-2-3 is no longer widely used, and many modern spreadsheet programs may not be able to open .123 files directly.

    Here are a few possible applications that can be used to open and view .123 files:

    1. Apache OpenOffice Calc: OpenOffice Calc is a free and open-source spreadsheet program that can open .123 files. It is compatible with Windows, macOS, and Linux operating systems.
    2. LibreOffice Calc: LibreOffice Calc is another free and open-source spreadsheet program that can open .123 files. It is very similar to OpenOffice Calc and is also compatible with Windows, macOS, and Linux.
    3. Microsoft Excel: Although Microsoft Excel is primarily designed for its own file formats (.xlsx, .xls), it may be able to open .123 files as well. However, compatibility may vary depending on the version of Excel you are using.
    4. Gnumeric: Gnumeric is a lightweight and free spreadsheet program that can open .123 files. It is available for Linux, Windows, and macOS.
    5. Online file converters: There are various online file conversion services available that can convert .123 files to more modern spreadsheet formats like .xlsx or .csv. Once converted, you can use any spreadsheet program to open the converted file.

    It is important to note that the compatibility and functionality of these programs may vary, and some features of the original .123 file may not be fully supported. It is recommended to make a backup of the .123 file before attempting to open it in any of these programs.

  • Are there any specific steps or instructions to follow in order to successfully open a .123 file on a computer or mobile device?

    To successfully open a .123 file on a computer or mobile device, you can follow these steps:

    1. Determine the file type: .123 files are typically associated with Lotus 1-2-3, a discontinued spreadsheet program. Ensure that you have a compatible software or application installed on your device to open this file type.
    2. Install Lotus 1-2-3 or compatible software: If you don't have Lotus 1-2-3 installed, search for a compatible spreadsheet program that can handle .123 files. Examples include Microsoft Excel, LibreOffice Calc, or Google Sheets. Install the software if necessary.
    3. Open the file using the software: Once you have a suitable program installed, launch it on your computer or mobile device. Then, either use the "File" menu and select "Open" or use the software's dedicated "Open" button to browse for the .123 file.
    4. Locate and select the .123 file: Use the file browser provided by the software to navigate to the location where the .123 file is stored. Select the file and click "Open" or a similar option to load it into the software.
    5. Adjust any import settings: Depending on the software, you may be presented with import settings or options specific to the .123 file format. Ensure that the settings are appropriate for your needs and click "OK" or "Import" to proceed.
    6. View and edit the .123 file: Once the file is successfully opened, you can view and edit the spreadsheet data as needed. Save any changes you make using the software's "Save" or "Save As" feature.

    Note: If the .123 file is not associated with Lotus 1-2-3 or any compatible software, it's possible that it may be a different file type with a similar extension. In such cases, you may need to determine the correct program to open it or convert it to a different format.
