Our file is a numbered collection of items that we put into each box, and each item number will correspond with a box number. We can place our item into a box in any order we want, as long as the box is empty. As we put an item into each box, we put a sticky note onto the same box with the number of the next empty box that we are going to use.
We can think of this as a bread crumb trail that will show the next person what order to follow when retrieving the items from the row of boxes. The box that we place our final item into will be marked with a sticker that says 'end' onto it to show that this is the end of the file.
As we place items into each box, we can write down on a piece of paper how many items file segments we placed into boxes blocks , and list the order that we placed them in. We will end up with a File Allocation Table with a Busy Column box empty or full , and a Next Column the next box number you need to look at. Now that we have documented everything, we can ask anyone to read our table and retrieve our file, as long as they know what the starting block number of that file is, regardless of the order that we placed our items into the boxes.
They will know when they have come to the end of the file when they find the box with the 'end' sticker on it that matches the number of the last file segment on our list.
FAT32 performs very well when there is a lot of free space on a hard drive. Speed generally deteriorates over time as files are deleted and new files are added because file fragments jumble things up a bit for FAT This is due to FAT writing files to the hard drive in empty blocks as it finds them. Fragments of the same file are often assigned to empty blocks in different locations on the hard drive wherever empty spaces are.
This adds extra seek time to file operations as the hard drive has to move backward and forward when retrieving all the fragments of each file. With mechanical hard drives this makes the physical read and write head seek around the platter and can slow things down with time. Defragmenting combats this effect by reordering blocks into consecutive lines, freeing up empty blocks between file allocations, and making files faster to read because they are all consecutively stored next to one another.
How is it used? Where is it used? Who would use it? Where is it commonly found? Why is it ideal for the place it is found? It has remained popular with these types of storage devices thanks to its relative reliability and compatibility with a wide array of operating systems and devices. It is a departure from FAT in many ways.
It also keeps logs of all activity on a hard drive in a log. All of this information is stored in hidden files on the hard drive that contain metadata. They can be accessed with special software tools. This is mainly for forensic use, and most end users have no clue that they are there. This is because of the advanced encryption and security standards that it supports.
Sectors are the smallest size of an individually addressable area of memory, while a cluster is a contiguous series of sectors.
The size of a cluster is defined inside the Master Boot Record of the hard drive. In computing, a file system determines how data is stored and retrieved. Without using the file system, information placed in a storage medium would be one large body of data with no way to know where one piece of information stops and the next one begins. FAT32 is one of the oldest of the three file systems available to Windows. The FAT32 contains four bytes per cluster inside the file allocation table.
It is known as the most updated file system from Microsoft for Windows OS. This system is compatible with flash drives, thumb drives, or memory cards. The full form of exFAT is an extended file allocation table. It has large limits on file and partition sizes. It optimizes exFAT for flash drives. NTFS is a modern-day file system that is used by default used by Windows.
This file system has the file size and partition size limits, which are so huge that you are not likely to run up with disk space. It supports file permissions for security, a change in a journal that allows you to recover when your computer crashes, reach disk quota limits, shadow copies of your backup, etc.
Skip to content. Usage: Flash drives will often be formatted with FAT32 for maximum compatibility. Be sure not to store a single file that is larger than 4 GB. However, it has limits on file size and partition size, which may cause inconvenience if you want to store large files. However, I have formatted my file system to FAT32 and stored important files in it. MiniTool Partition Wizard Free Edition is a free partition manager trusted by tens of millions of users.
Step 1. Install it on your computer and launch it to get the main interface. Free Download. Step 2. Step 4. After the conversion is completed, you can click Close to exit the window. It is a file system introduced by Microsoft in , which is similar to FAT32 files system, but does not have the limits of FAT32 file system.
