Comparing the data set size display in the operating system
On the screen shots below you will see the Recorded dataset information from Windows, Ubuntu and Mac OS respectively.
Operating system | Dataset calculation |
Windows
| The Size on disk field shown in Windows uses a calculation so that 1024 bytes equals 1 kilobyte. In the same manner, 1024 kilobytes equals 1 megabyte. Therefore, for this dataset, it is reporting 941 MB. However, you will see that in the brackets next to 941 megabytes, it shows the real value in bytes - 986 783 744 bytes. |
Ubuntu
| The Ubuntu operating system uses a base-10 calculation where 1000 bytes equals 1 kilobyte. With this in mind, it is rounding up those 986 783 744 bytes to 986 MB. |
Mac
| Similarly to Ubuntu, the Mac operating system display the base-10 value in megabytes (986,8 MB). |
The same as MAC or Ubuntu, NavVis IVION Processing uses a base-10 calculation and this same Dataset is consuming 986 MB.
