Call of Duty: Modern Warfare III has different minimum, recommended, and higher-performance PC targets. The game and its shared Call of Duty components can also change with updates, so check the current official specification and your launcher before reserving disk space.
First identify the exact title: Modern Warfare III (2023) is not the older Modern Warfare 3 (2011). Review the publisher's current PC requirements for your chosen quality target, including Windows version, CPU, GPU, memory, graphics API, network connection, and storage. Do not rely on one static storage number: selected content packs, high-resolution assets, and patches can change installed size.
As a launch-era reference, Activision listed these desktop targets: multiplayer-only minimum, Windows 10 64-bit, Core i3-6100 or Ryzen 3 1200, 8 GB RAM, GTX 960/GTX 1650 or RX 470, and 79 GB of SSD space; full-game minimum, Core i5-6600 or Ryzen 5 1400 with the same 8 GB RAM and GPU class, and 149 GB; recommended 60 FPS at high settings, Core i7-6700K or Ryzen 5 1600X, 16 GB RAM, GTX 1080 Ti/RTX 3060 or RX 6600 XT/Arc A770, and 149 GB. Activision also lists DirectX 12, broadband internet, and optional high-resolution cache space. These figures can change with updates, so confirm the official current requirements before installing.
In Windows, open Settings > System > About to see processor and RAM. Open Device Manager > Display adapters for the GPU model, or use dxdiag for driver details. Compare the exact model, not just a brand name. An SSD helps loading but cannot make an unsupported GPU meet rendering requirements.
Open File Explorer > This PC and check the drive where your launcher installs games. Leave headroom beyond the listed game size for downloads, temporary unpacking, shader caches, Windows updates, and future patches. The launcher may temporarily need much more free space than the final installed files occupy.
If C: is tight, go to Settings > System > Storage > Cleanup recommendations. Review temporary files individually before removing them. Do not delete Downloads, old Windows installation files, or game folders you still need merely because they appear large. Uninstall unused games through their launchers and let the launcher move the library when supported rather than dragging only a program folder.
Step 1. Check the target SSD's available capacity and file system in File Explorer. Back up local save files or configuration folders that are not cloud-synced; do not assume every game's saves live in the installation directory.
Step 2. In Steam, Battle.net, or the launcher you actually use, create or select a library folder on the SSD. Use the launcher's Move or Change install location function if offered. If the launcher has no move function, uninstall and reinstall the game to the new library rather than copying incomplete files.
Step 3. Let the launcher verify files, start the game, and confirm the account, content packs, and saved settings. Only remove the old installation after the new location launches successfully.
Qiling Disk Master is a partition manager, not a way to bypass hardware requirements. If unallocated space is already adjacent to the game partition on the same physical disk, you may be able to extend that partition after a backup. Do not confuse unused capacity on another disk with adjacent unallocated space. When no suitable space exists, use a larger compatible SSD or move other libraries instead.
A clone to a larger SSD can preserve Windows and applications during an upgrade, but it overwrites the selected destination and requires a separate first-boot test. Choose it only when you are replacing the drive rather than simply making room for one game.
Use the publisher's current PC specification, check your actual Windows hardware and free space, then use the launcher's supported move function or a verified SSD upgrade.
