Filendelser

Filendelser, also known as file extensions, are the suffixes added to the end of a filename to indicate the type of file and the format it uses. They are typically a combination of three or four letters, preceded by a period. For example, a Microsoft Word document might have the extension .docx, while a JPEG image file might have the extension .jpg. File extensions are an essential part of computer systems, as they help users and applications identify the file type and determine how to handle it. They also play a crucial role in ensuring data integrity and security, as they can be used to restrict access to certain file types or to prevent the execution of potentially harmful files. In some cases, file extensions can also be used to indicate the version of a file format or the specific application that created it. However, it is important to note that file extensions can sometimes be misleading or incorrect, as they can be changed or removed without affecting the actual content of the file. Therefore, it is always a good practice to verify the file type and format using other methods, such as examining the file header or using specialized software.
