Introduction

NavVis IVION Cloud Processing entitles every user to a limited storage space. Every new Recorded dataset that a user uploads to their instance, substracts the storage space by its size.

Questions

How is the Dataset file size calculated in NavVis IVION Cloud Processing?

Why is the dataset size on Windows smaller than the size on NavVis IVION Processing?

Answer

On the illustration below you will see the Recorded dataset information from Windows, Ubuntu and MAC OS, respectively.

The "size on disk" Windows is using a calculation such 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.

On the other hand, Ubuntu operating system, is using 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. 

Similarly, MAC OS is reporting the "base 10" value in megabytes - 986,8 MB.

Just like MAC or Ubuntu, NavVis IVION Processing is using a base 10 calculation and this same dataset is consuming 986 MB. 

Conclusion

If you are a Windows user, you might notice that the size on disk of your datasets does not quite match the size occupied on NavVis IVION Processing. This article explains you why is the calculation on Windows different and that the NavVis IVION Processing reports the true value.
