When to use it

Use the free space currently shown on the destination drive, not its advertised capacity. Games A, B and C are simulated installations of 90, 65 and 40 GB; they are not named game specifications.

Inputs

Inputs Default
Game A (GB) 90
Game B (GB) 65
Game C (GB) 40
Free space (GB) 300
Reserve (GB) 50

Calculation method

Add the installation sizes. Subtract that total from current free space, then subtract the chosen reserve. If this final margin is negative, the amount to free is its magnitude; otherwise it is zero.

90 [Game A GB] + 65 [Game B GB] + 40 [Game C GB] → Install total GB

300 [Free space GB]-Install total GB → After install GB

After install GB-50 [Reserve GB] → After reserve GB

(abs(After reserve GB)-After reserve GB)/2 → Space needed GB

Change one input

Change free space from 300 to 180 GB, leaving the 50 GB reserve unchanged. The final margin changes from 55 to −65 GB and the extra space needed changes from 0 to 65 GB.

Result Default Changed
Install total (GB) 195 195
After install (GB) 105 -15
After reserve (GB) 55 -65
Space needed (GB) 0 65

Results are displayed to at most two decimal places; later formulas use unrounded values.

Scope and limits

  • Use installed sizes, not download sizes.
  • The reserve is user chosen, not a platform recommendation.
  • Negative margins show a shortfall.

Inputs must be nonnegative and use compatible units. GB is decimal; GiB is binary. Set the actual unit rather than just relabelling a number. Installation and update workspace varies by game; this arithmetic does not guarantee installation will succeed.

Common questions

Why use current free space instead of 1 TB on the box?

System files and existing data already occupy space, and GB/GiB reporting differs. Read the destination drive’s current free space and check the game’s installation requirements.

How to import your template

We recommend using the latest version of Calvance.

  1. Save the file. Choose Download template and save the .calvx file to Files on your iPhone or iPad. From a computer, you can send it to your device with AirDrop.
  2. Open Import. In All Canvases in Calvance, tap the add button to open the template screen, then choose Import.
  3. Choose the file. Select the saved .calvx file to create your own canvas. Importing uses one canvas from your allowance.
