File Sizes Explained

File size measures the size of a computer file and is typically measured in bytes with a prefix. The smallest unit of measurement in computers is bit and comes from binary diginformation technology. A chip has only 2 digits - zero and ane. The nix is besides known as false (off) state and the i is known equally true (on).

The bits are combined in groups in order to grade larger units. The adjacent unit larger than the bit is the byte which is formed by the combination of eight $.25 and can represent a value from 0 to 255 which is ii to the ability of 8 - all the possible combinations of the 8 $.25 that it includes.

The next larger units after the byte are named kilobyte, megabyte, gigabyte, terabyte and and then on which atomic number 82 to cracking deal of confusion. Though the kilo prefix in the metric system means k (e.g. grams) in computers it means 1024 (due east.g. bytes). In guild to correct this mess the International Electrotechnical Committee (IEC) approved a new IEC International Standard in December 1998. You can detect the list of IEC metric and binary names in the table at the end of this article.

How to Convert File Sizes

As already described the smallest unit in computers is the flake. Converting file sizes is like to converting other units with some small differences.

To catechumen $.25 to bytes yous have to divide the count of $.25 to eight as one byte contains 8 $.25. To further catechumen the bytes to kilobytes you accept to split the value by 1024. To convert from kilobytes to megabytes you have to split up the kilobytes to 1024 again and and so on. This is a bit dissimilar than in metric organisation where values are divided past yard to convert them to the side by side larger unit of measurement. For instance 1 km is 1000 meters.

Why one Megabyte is 1024 Kilobytes Instead of yard Kilobytes?

Where does the 1024 number come from? Well most numbers in computers are two to the power of 10, and 1024 is ii to the ability of x. That is because computers use the binary arrangement - not the decimal. Of form you can represent the decimal or any other system on a figurer, but at its cadre hardware level the calculator uses the binary organization. In 1998 IEC introduced new naming convention for the file sizes which now creates even more than confusion. If you lot were using computers for a long time you may think that a megabyte is yet 1024 kilobytes, but that is no longer the case. Megabyte is now m kilobytes which on the other hand is one yard bytes. The quondam multiples of 1024 units are now with new prefixes and mebibyte is 1024 kibibytes and a kibibyte is 1024 bytes. Changing something existing and well established and known by billions of people in my opinion is not a skilful idea, but information technology is my own personal position. It would exist much less confusing to use new unit names, but that would not represent to the metric system naming convention. In that location was no perfect solution so we have to become used to information technology.

If y'all are purchasing a storage device yous can run across that a 2TB difficult drives displays equally 1.82 TB which is much smaller in Windows. Windows yet uses the old unit naming convention which causes the discrepancy. Of class the new naming convention is very welcome for the storage manufacturers as they now provide ten% less storage while using the same naming convention. And then carry in ming that when purchasing a new hard bulldoze or memory card.

File Size Metric and IEC binary prefixes

Here is a list of some of the commonly used units in the metric and their corresponding IEC binary prefixes:

Proper name	Size		Name	Size
kilobyte (kB)	10 three		kibibyte (KiB)	2 10
megabyte (MB)	x 6		mebibyte(MiB)	2 20
gigabyte (GB)	10 9		gibibyte (GiB)	two xxx
terabyte (TB)	10 12		tebibyte (TiB)	ii forty
petabyte (Lead)	10 15		pebibyte (PiB)	2 50
exabyte (EB)	x 18		exbibyte (EiB)	two threescore
zettabyte (ZB)	10 21		zebibyte (ZiB)	2 lxx
yottabyte (YB)	x 24		yobibyte (YiB)	2 80

File Size Limits - File Systems

File sizes are limited by the file arrangement that is used and its implementation. Here are details on the common file systems:

	FAT16	FAT32	NTFS
Maximum File Size	2 32 - ane bytes	2 32 - 1 bytes	two 64 - 1 KB
Maximum Book Size	four GB	32 GB	2 64 clusters
Files Per Book	2 16	2 22	ii 32 - 1

View File Sizes in Windows File Explorer

The cadre file management application in Windows ten, 8, 7, Vista, XP is the Windows File Explorer. You lot tin can use it to manage files and view file sizes. As you can see on the screenshot beneath nosotros accept a list of some prototype files. The rightmost "Size" column displays the size of the files. To view the sizes of the files you accept to switch the view to "Details". To exercise that click the "More than options" button at the height-right corner of Windows Explorer and select "Details".

The size is automatically displayed in the most appropriate units - in this case KB. Clicking the column title the files will be sorted by size. Unfortunately the binder sizes are non listed in the "Size" column. To view those you can use our gratis Folder Size Explorer awarding which will reveal all folder sizes and all missing disk space.

If you want more precise information you can right-click a file and select 'Backdrop'. The following file properties panel will be displayed:

Here you lot can find the exact file size and also the other file properties like created, modified, and accessed times. Some of the file attributes are also listed and tin can be toggled. These are the read-simply and hidden flags. Y'all can also correct-click a folder and select "Backdrop" from the popup card. That will brandish the information about the folder and will also summate its size. Note that this may take some fourth dimension for large folders. You accept to wait until the size property stops changing. There is no indication when the calculation is complete and the size property may stay for several seconds without a change so continue to grow. Make certain to expect at to the lowest degree x seconds after the concluding change to be sure that the calculation is complete.

File Size Basics - Common File Sizes

If yous are new to computers and files here are several samples of common file formats (types) and their boilerplate sizes:

1. Text File (TXT) - Text files are one of the smallest file types. Their sizes are equal to the count of characters they contain. A few pages text file is typically 1-2 KB. These are considered "TINY" files.
2. Discussion documents (Physician, DOCX) - These files contain styling and formatting and are quite larger. A few pages Doctor file without images is nearly 50-300KB. these are considered "SMALL" files.
3. A photo (JPG) from a common 12 MPX photographic camera is about iii-5 MB. These are considered "MEDIUM" size.
4. MP3 Audio File - a full length song is between 3 and 10 MB depending on its duration and quality (compression). The other compressed audio files are too in this range - MP4, FLAC, OGG etc. Uncompressed WAV files used in CDs are very large. They are about 10 MB per minute - eastward.g. about 70 MB for a 7 minutes vocal.
5. A 10 2d low resolution 640X480 AVI video is well-nigh 15 MB - This size leans towards "LARGE".
6. A 1-1.5 hr video with a lower SD resolution is about 700-1000MB This is considered a "LARGE" file.
7. A 1-1.5 hour video with Total HD quality is about 7-10GB depending on the codec (compression) that is used to shop it.

If you are new to files and computers, the above sample file sizes will give you a rough thought about file types and their common file sizes. Of course those are approximate sizes and may vary, just the files of those types are approximately in those size ranges.

Mutual Media and Storage Sizes

1. Diskette 5" 360 KB Single Sided - 720KB Double Sided - no longer used
2. Diskette 3" i.44 MB - no longer used
3. CD (Compact Disk) - 650-700MB (74-80 minutes)
4. DVD-R Single Layer - four.7 GB
5. DVD-R Dual Layer - 8.five GB
6. Difficult Bulldoze (HDD,SSD) - tin can vary from megabytes to Terabytes
7. Flash Drive (USB Stick) - can vary from megabytes to gigabytes

Size-related Questions

What is the largest file that I can send in electronic mail?

This depends both on the sender's and receiver's email service provider, but a files size of five to 10 MB is considered safe. This is about ii to v photos depending on their size. Large files can not be sent via email and ordinarily are shared using a file hosting service like Google Drive, Dropbox, or Microsoft OneDrive. You upload the file to i of those services and share the link with your partner via e-mail or a messaging awarding.

Can I send a video file via electronic mail?

Video files are unremarkably larger than 10MB and yous will not be able to send them as an zipper in an email Yous have to use a file sharing service to upload the video to the Internet and share a link to it with your friends. File sharing services provide option to password-protect your files and share them only with the users that you lot give access to.

Can I reduce file sizes?

Aye you can using a file compression tool like WinZip, 7Zip, WinRAR and others. Using those tools you can archive files to compress them. In guild to alter or view the files they have to be extracted - decompressed. Please note that image, sound and video files can not be compressed every bit those formats already use internal compression. Compressing such files will either have well-nigh no result or can even make the compressed version larger than the original.
