A file extension is a set of characters at the end of a filename that denotes the type of file. File extensions are used to help identify the contents of a file and to determine what type of software should be used to open the file.
Most computer systems use file extensions to determine the file type. The file extension is usually three or four characters long and is preceded by a period. The file extension is followed by the filename.
Some common file extensions include .jpg for images, .pdf for PDF files, and .doc for Word documents.
The file extension is usually included in the file name when the file is stored on a computer. However, the file extension is not always displayed in the filename.
Windows systems hide the file extension by default. To see the file extension, you need to change the settings in the Folder Options window.
Some file extensions are automatically associated with a particular software program. For example, .doc files are usually opened with Microsoft Word, and .jpg files are usually opened with a photo viewer.
If you don’t have the appropriate software installed to open a file, you can download a free or trial version of the software from the software manufacturer’s website.
Some file extensions are associated with specific file types that can only be opened with special software. For example, .mov files are typically video files that can only be opened with a video player.
It’s important to know the file extension of a file before trying to open it. This can help you determine which software to use to open the file.

What does a file extension tell your computer quizlet?
What does a file extension tell your computer quizlet?
A file extension is a letters and/or numbers after the dot in a computer file name. File extensions tell your computer what kind of file it is. For example, the file name “picture.jpg” has the file extension “jpg” which tells your computer that the file is a JPEG image file.
Some file extensions are assigned by the program that created the file. For example, the file extension “doc” is assigned to Microsoft Word documents. Other file extensions are assigned by the operating system. For example, the file extension “mp3” is assigned to MP3 audio files.
Most file extensions are hidden. This means that you cannot see them when you are looking at the file names in Windows Explorer. To see the file extensions, you need to change the view of the folders to Details view.
What is the purpose of file extensions?
When you save a file on your computer, you might notice that it has a .doc, .pdf, or .jpg extension. What do these extensions mean, and what is their purpose?
Extensions are simply a way to identify the type of file a particular document is. For example, a .doc extension indicates that a document is a Word document, while a .pdf extension indicates that a document is a PDF file.
This system is used to help computer programs understand which type of file they are dealing with. For example, if you try to open a .pdf file in a program that can’t handle PDF files, the program will usually give you a warning and ask you if you want to open the file in a different program that can open PDF files.
Extensions can also help you identify the format of a file. For example, if you have a file that ends with the .jpg extension, you know that it is a JPEG image file.
Some extensions are also associated with certain programs. For example, the .doc extension is associated with Microsoft Word, while the .ppt extension is associated with Microsoft PowerPoint. This means that if you try to open a file with a .doc or .ppt extension, the program will usually start up automatically.
So, what’s the point of file extensions?
Simply put, file extensions help computer programs understand what type of file they are dealing with. This can be helpful for both the programs and the users, as it can make it easier to open files and understand their content.
What must happen when a file is saved?
When you save a file, the following must happen:
1. The operating system must save the file to disk.
2. The disk must be able to write to the file.
3. The disk must have enough free space to write the file.
4. The file must be saved in the correct format.
5. The file’s permissions must be set correctly.
6. The file’s owner must have permission to write to the file.
7. The file’s group must have permission to write to the file.
8. The file’s other users must have permission to write to the file.

What is a file file extension?
A file file extension is an identifier added to the end of a filename to indicate the file’s type. This identifier is used by computers to determine how to open the file.
File extensions are typically three or four letters long, and are typically appended to the filename after a dot. For example, the file “myfile.txt” would have the extension “txt”.
Some file extensions are built into the operating system, while others are custom created by the user. Common file extensions include:
.txt – Text file
.jpg – JPEG image
.mp3 – MP3 audio file
.avi – Video file
What will happen if we do not save a file?
If you do not save a file, it will be lost. Any changes you have made to the file will be lost, and the file will be reverted to the last saved version.
Where can I find recently saved files?
There are a few different ways to find recently saved files. One way is to look in your computer’s file explorer. Another way is to use the search bar on your computer.
One way to find your recently saved files is to look in your computer’s file explorer. The file explorer is a program that allows you to view and navigate through the files and folders on your computer. To open the file explorer, click on the “File Explorer” icon on your computer’s desktop.
The file explorer will open and display a list of the folders on your computer.

The “Date Modified” tab will list the files that were saved on your computer in the last few days, weeks, or months.
Another way to find your recently saved files is to use the search bar on your computer. The search bar is a program that allows you to search for files and folders on your computer. To open the search bar, click on the “Windows Logo” button in the bottom-left corner of your computer’s desktop.
The search bar will open and display a list of the files and folders on your computer. To search for recently saved files, type “recently saved” in the search bar and press the “Enter” key.
