Need more storage

Worth separating two different things first. Cloud storage and the drive inside the machine are not the same resource - a Microsoft 365 or OneDrive plan adds quota to your account, not space to the laptop. If the drive is what is full, the options below are the ones that actually change it.

1. Reclaim what is already on the drive

A new laptop commonly carries 20-40 GB that can be removed without losing any personal file:

• Settings > System > Storage > Temporary files - Windows Update cleanup, the previous Windows installation, and the delivery optimization cache
• In an elevated Command Prompt, powercfg /h off deletes hiberfil.sys, which is sized to installed RAM and is often 8-16 GB on a modern machine
• Settings > System > Storage > Storage Sense, to stop the same categories refilling silently

If the drive is 256 GB and only 15 GB is free, this step often decides whether hardware is needed at all. It is also worth checking what the space is actually going to before buying anything - Settings > System > Storage shows the breakdown per category.

2. microSD card, if the model has a reader

Several Galaxy Book models include a microSD slot. Folders can be relocated rather than copied: right-click Documents, Pictures or Downloads > Properties > Location > Move, then point it at the card. Cards are slow and are a poor place for installed applications, but they are fine for media and archives.

3. The internal SSD

Two variants exist and they behave very differently:

• Onboard / soldered - there is no slot and nothing can be added. This has to be confirmed before ordering any part.
• M.2 2280 NVMe slot - the existing drive can be replaced, or a second one fitted on models with a free slot.

The reliable source is the service manual or the support page for that exact model number, not the marketing name. msinfo32 gives the model, and the maintenance section of the manual states whether the SSD is customer-replaceable and which length the slot accepts. On several thin Galaxy Books the drive is not user-accessible, and opening the chassis can affect the warranty.

4. External SSD over USB-C

The least invasive option and usually the most capacity per unit of cost. It handles games, media and archives well; it is not a suitable system drive.

One caution about moving user folders

If Documents or Pictures are redirected to a card or an external drive and that device is later removed, the folders appear empty until it is reconnected, and some applications quietly recreate their data in the default location. Move one folder at a time and confirm the applications still find their files before moving the next.

If you purchase a Microsoft 365 plan, you can move your files to the cloud and access them using Files On-Demand.

When you open a cloud-only file, it downloads to your computer and becomes locally available.

With Storage Sense enabled, the file can automatically return to being cloud-only.

Hi. I'm David, and I'm happy to help you.

If you would like to increase your computer's internal storage, please let me know the exact model of your Samsung Galaxy so I can check the best options for you.

If you prefer, you can share a screenshot of your system information.

• Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.

Looking forward to your reply.
