What kind of information do you get from a file extension? Is it something you never thought about? Have you ever wondered about the technical stuff behind multimedia files? Well, today we want to share with you some interesting facts about file extensions and their importance.
File extensions are often associated with a particular type of media. For example,.jpg stands for JPEG image format. These extensions are generally attached at the end of a file name. Some extensions might include additional data to specify the features, such as MP3 or MPG. When you open a file, you usually see its extension displayed at the top left corner of the program window.
There are over 200 different file types and formats, and each one has its unique extension. The reason why these various extensions exist is simple – they allow us to categorize our files into groups. This helps us easily find them later.
Most-Used Multimedia File extensions
1. .jpg: JPEG image format
The JPEG (pronounced jaypeg) image format was created in 1992 by David Boggs and Thomas G. Lane at Cognex Corporation. It’s now widely used because it compresses the data required to store an image without visible quality degradation visit Casino en ligne. This makes it ideal for email attachments or web pages. However, it can also take longer to load than other types of image formats.
2. .mpg: MPEG video/audio format
MPEG stands for Motion Pictures Expert Group. MPEG 1 refers to a standard for digital audio coding, while MPEG 2 refers to the standard for digital video compression. As mentioned earlier, most audio and video players have built-in support for.mpg, .avi, and .mpeg files.
They play back sound and video using digital technology that converts analog signals into digital ones. That means your videos will be compatible with all modern devices. Unfortunately, there isn’t much you can do with .mov files besides watching them on non-digital devices.
3. .pdf: Portable Document Format
Portable document format (.pdf), developed by Adobe Systems Inc., is considered the de facto standard for exchanging documents online. PDF contains instructions that define how browsers should display the text and graphics inside any document stored in .pdf files.
One issue with.pdf files is that they don’t seem to work well when printed on paper printers. Many people use word processors, like Microsoft Word, to create documents, then save them as .pdf. If this happens, many computers won’t print out the contents correctly. In addition to this problem, some older printers may not even recognize the new file extension.
However, there are ways around this problem. You could scan the document and save it in another format, such as .tif, which is supported by most scanners. Another solution would be to choose a more printer-friendly file format such as Postscript.
4. .xls: Microsoft Excel spreadsheet application
Microsoft Excel spreadsheets (.xls) were originally designed for tracking financial transactions and analyzing business information. Users can also use Excel to present their finances. Spreadsheets (.xls) provide great flexibility so they’re perfect for storing large amounts of numbers, formulas, and charts.
If you want to make sure you’ll have access to the same data everywhere else, consider saving your spreadsheets in .xsl format. Because .xls files contain large amounts of data, it’s best to keep the size to under 5 megabytes (MB).
5. .doc: Microsoft Office Documents
Office documents (.doc) come in several flavors including Word (.docx), PowerPoint (.pptx), Excel (.xlsx), and others. Word is probably the most familiar to the average person; however, many users find Excel easier for doing math calculations or processing complex data sets.
While one advantage of .doc over .txt files is that they’re generally smaller, they require special software to view on a computer. There is free software available so if you simply need plain text, try switching to .txt files. For those who need to edit the formatting themselves, Word provides features similar to HTML editors that allow users to add custom styles and fonts for a particular document.
6. .rtf: Rich Text File
Rich text files (.rtf) offer a lot of advantages of .odt text editor but extend the functionality in different directions. Often they include rich content such as pictures, tables, embedded objects, hyperlinks, and other useful media types.
Also known simply as RTF files,.rtf files are typically used as templates because they store all of the necessary formatting settings needed to easily replicate an entire document. It’s easy to see why these files are very popular among designers.
