In certain cases, there may be a slight difference between the stated storage capacity in Tresorit and your OSX, iOS or Linux file manager. This is due to your Operating Systems decision to process and store data in a different format than the industry standard.
Decimal vs Binary measurements
Storage device manufacturers measure capacity using the decimal system (base 10), so 1 gigabyte (GB) is calculated as exactly 1,000,000,000 bytes. The capacity of the storage media for example in your Mac, iPad, iPod, iPhone or any other Apple hardware, is measured using this decimal system. This is detailed on the product packaging and online through the statement "1 GB = 1 billion bytes."
However, when you view the actual storage capacity of your iPhone or iPad, the capacity is reported using the binary system (base 2) of measurement. In binary, 1 GB is calculated as 1,073,741,824 bytes.
What this means in practice
The way decimal and binary numeral systems measure a GB is what causes a 32 GB data to appear as approximately 28 GB, even though the data still has 32 billion bytes (not 28 billion bytes), as reported.
As Tresorit was not designed to use Apple products' native measurement practices, its storage display will mirror these differences. Don’t worry,your data is safe and nothing is missing. Note that this is only the result of measurement practices and your storage capacity is the same no matter which system (decimal or binary) is used.
Change your settings
Change the storage measurement in Tresorit to match your operating system. Head to the General tab under Preferences, and check the box left of "Show sizes in GiB".
