On macOS and Linux, storage sizes shown in Tresorit may differ from those shown by your operating system. This happens because storage sizes are calculated differently.
Decimal vs. binary measurements
Storage manufacturers use the decimal system (base 10): 1 GB = 1,000,000,000 bytes
Operating systems typically use the binary system (base 2): 1 GiB = 1,073,741,824 bytes
Tresorit displays storage sizes using decimal units by default.
In practice
The same data may appear with different sizes depending on where it is displayed – the byte count is unchanged, and no files are missing or altered.
Example: 32 GB can appear as ~28-30 GB in the different system views.
Change Tresorit settings
You can change the storage measurement in Tresorit to match your operating system:
Go to Preferences → General and enable Show sizes in GiB.
