Why do identical files have different sizes?
Because of the way file systems organize and track your data on disk, size may be displayed differently in one place than in another. When backing up online, my pictures only take up ~65 GB, but ~88 GB are reported on my computer.
What factors impact on file size?
What factors affect file size? File size is affected by three factors: pixel dimensions, image format and bit depth. In general, reducing your pixel dimensions to only what you actually require, using the JPEG format and setting the lowest possible bit depth will give you the smallest file size.
What is the difference between size and size on disk?
When you see the size of the file on the properties page, it shows the actual file size. On the other hand, the size on the disk indicates the total number of bytes occupied by a file on a hard drive.
What affects the size of a bitmap image?
Two factors that affect the size of the bitmap image is resolution and depth. Resolution is the number of pixels contained in the image. Bitmap file is very dependent on the resolution.
What are the key factors that affect the quality and file size of a sound?
A number of factors can affect the size of a sound file and the quality of its playback. These include the sample rate, sample resolution and the way that the file is compressed. When you speak or play music into a microphone, the microphone takes the sound waves and converts them into a voltage.
Why is the same file a different size in different places?
This is something that’s confused computer users for many years: the exact same file can show as taking up a different amount of space, depending on where you look and the characteristics of different disk drives. Copy that file online and things get even more confusing. I don’t think I’ve ever seen this be something to worry about.
Why are there so many different image formats?
An MPEG file uses a complex algorithm like a JPEG file does — it tries to eliminate repetition between frames to significantly compress video information. In addition it allows a soundtrack (which animated GIFs do not). Because a typical sequence has hundreds or thousands of frames, file sizes can still get quite large.
Why are PDFs different sizes when created from the same?
So, while I know there is a lot of detail in the drawing file itself, all the editing is done in the CAD file. The PDF is used to turn the drawing into something on paper and to combine PDFs. The PDFs many times have a larger size then the drawing itself.
Why are file sizes slightly different between windows and Linux?
I used ls -l on the Linux and just looked at the Properties on the Windows for file size info. Maybe because Windows shows file sizes in kbs, mbs, gbs, While linux shows them in kibs, mibs, gibs…? One kb is 1000 bytes, while one kib is 1024 bytes, and one mib 1024 kibs. Other possible reason is probably metadata.
