What is CDR file format?

A CDR file is a vector graphics file created by CorelDraw, a popular graphic-design program. It stores a single image made up of vector graphics, text, and bitmap images. Vector graphics are made up of lines, shapes, and curves that are based on mathematical equations, and are used to create illustrations, logos, and other graphic designs. CDR files can contain important design elements including layers, color tables, effects, and objects. They are usually saved as compressed files, which helps to reduce file size. CDR files are frequently used by professional graphic artists, but they can also be used by amateur users to create custom logos and drawings. CDR files are not compatible with many other programs, so it is important to use CorelDraw to open them and make changes. Once a file is saved in a CDR format, other programs may not be able to open it. However, some programs may be able to import and export CDR files.

What is XLSB file format?

The XLSB file format is a binary file format used for Microsoft Excel workbooks. Unlike the XLSX and XLSM file formats, which are based on the Open XML format, XLSB is a binary format that stores data in a binary structure. This binary structure allows for faster file processing and improved performance compared to the XML-based formats.

XLSB files contain spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. The binary format optimizes storage and calculation efficiency, making it well-suited for large datasets and complex calculations. It also provides better data integrity and recovery capabilities, as the binary structure reduces the risk of file corruption.

Due to its binary nature, XLSB files are not easily readable or editable by humans. They are primarily intended for use by Excel and other applications that can read and process the binary format. However, Excel provides full compatibility and support for opening, editing, and saving XLSB files.

The advantages of using XLSB files include faster file operations, reduced file size compared to XML-based formats, and improved performance in terms of opening, saving, and recalculating complex workbooks. XLSB files are particularly useful for workbooks that involve large amounts of data or complex formulas.
