Questions and answers

  • What is the significance of the ._XLSX file format and how does it differ from the regular .XLSX format?

    The ._XLSX file format is not a standard file format. It appears to be an extension used by some software applications or operating systems to denote a temporary or backup file.

    On the other hand, the regular .XLSX format is the file extension used by Microsoft Excel to save spreadsheets in the Open XML format. It is a widely used and accepted file format for storing and sharing spreadsheet data.

    It is important to note that the significance, features, and differences of the ._XLSX file format, if any, would depend on the specific software or system that utilizes it.

  • How can I identify and differentiate a ._XLSX file from other file types?

    You can identify and differentiate a ._XLSX file from other file types by examining its file extension and its internal file structure.

    1. File Extension: The file extension of a ._XLSX file is ".xlsx". This extension indicates that the file is a Microsoft Excel spreadsheet file. However, it is important to note that the file extension alone may not always be reliable, as it can be easily changed or manipulated.
    2. Internal File Structure: The ._XLSX file format is based on the Office Open XML (OOXML) standard. It is essentially a ZIP archive containing various XML files and other resources. You can differentiate a ._XLSX file from other file types by examining its internal structure. Here's how:

    a. Rename the file extension from ".xlsx" to ".zip".

    b. Extract the contents of the ZIP archive.

    c. Look for specific files and directories that are unique to a ._XLSX file. For example:

    - The presence of a directory named "_rels" containing relationship files.

    - The presence of a file named "[Content_Types].xml" that describes the content types of other files in the archive.

    - The presence of a directory named "xl" containing XML files related to the spreadsheet.

    - The presence of a file named "workbook.xml" that defines the structure of the workbook.

    - The presence of a file named "sharedStrings.xml" that stores shared string values used in the spreadsheet.

    By examining the file extension and the internal file structure, you can reliably identify and differentiate a ._XLSX file from other file types.

  • What are the various methods or software options available to open and view a ._XLSX file on different operating systems?
