Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsBefore you buy a digital Nintendo Switch game, check two things: the free space shown under System Settings > Data Management and the exact storage requirement on that game’s Nintendo eShop listing. The Data Management screen reports available System Memory and, when one is inserted, available microSD-card space.
If the requirement is larger than the space you can use, archive software you are not playing or add a compatible microSD card. Archiving keeps the game’s HOME Menu icon and save data while removing the downloadable software so it can be downloaded again later.

The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- From the HOME Menu, open System Settings.
- Scroll down the left-hand menu and select Data Management.
- Read the available space shown at the top of the screen. You will see a System Memory figure; if a microSD card is inserted and recognized, its available space is shown as well.
- Open the Nintendo eShop listing for the game you intend to buy and find its stated storage requirement.
- Compare the game’s requirement with the storage location that will hold the download. If you do not have enough room, archive software you no longer need immediately or plan for a compatible microSD card before purchasing.
Do not estimate from the game’s genre, publisher or cartridge size. Nintendo’s guidance is to verify the required space for the individual digital title in the eShop, because requirements differ from game to game.

What the two numbers on Data Management mean
System Memory
System Memory is the storage built into the console. The Data Management screen’s available-space value is the amount currently free there, after the system and any stored content have been accounted for.
Save data is kept in System Memory. It cannot be saved to or copied to a microSD card, so adding a card does not relocate your game saves or create a second save-data destination.
microSD card space
When a compatible microSD card is inserted, the same screen reports the card’s available space separately from System Memory. Downloaded software can use the card, as can software updates and downloadable content. Screenshots and videos can also be stored there.
These are separate pools. A game requirement is not automatically satisfied merely because the combined total looks large: you need enough available space in the location used for the download. Check the values individually and leave room for any additional content you intend to download.
Rank #2
- EXPAND YOUR STORAGE. Insert your card to add massive storage up to 1.5TB[1] to your Android smartphones and tablets, digital cameras, and laptops.
- SPACE FOR MORE. With expansive capacities up to 1.5TB[1], capture and store hours of Full HD video[4], movies, music, games, photos, and podcasts.
- MOVE FILES FAST. Use your card with the SANDISK QuickFlow microSD UHS-I Card USB-A Reader[6] to achieve up to 195MB/s[2] read speeds [128GB-1.5TB models] and offload your content fast.
- LOAD APPS IN A SNAP. Rated A1[3], the SANDISK Ultra microSD card is optimized for faster app launch and overall app performance.
- EASY CONTENT MANAGEMENT. Easily back up, organize, and transfer your photos and videos with the SANDISK Memory Zone desktop or Android mobile app[5].
Find the game’s exact requirement before paying
Open the intended game in Nintendo eShop and read the storage information on its product page before completing the purchase. The figure belongs to that particular listing; there is no reliable universal “average” download size that can replace it.
Nintendo Support specifically advises checking the required space before buying a digital version. The amount of storage you ultimately need can also depend on the number and type of games you keep downloaded and on extra content such as updates or downloadable content.
Compare your situation with the listing
Use this four-part comparison rather than looking at only one number:
Recommended Free Tools
| Item to check | Where to find it | Why it matters |
|---|---|---|
| Game requirement | The individual Nintendo eShop listing | This is the title-specific amount Nintendo says to verify before purchase. |
| Free System Memory | System Settings > Data Management | Save data remains here, and this is the console’s built-in free space. |
| Free microSD space | The top of Data Management when a card is inserted | This can hold downloaded software, updates, DLC, screenshots and videos. |
| Your download plan | Your own library and content choices | Keeping several games, updates or DLC downloaded requires more room than one initial installation. |
If the listed requirement fits in the available space you plan to use, the storage check passes. If it does not, make room first; a purchase does not eliminate the need for free storage to download the software.
Rank #3
- Nintendo Switch 2 uses a new standard of expandable memory card called microSD Express (sold separately). This kind of memory card is needed for faster access speeds and to ensure games will run smoothly.
- Please note: Nintendo Switch 2 is only compatible with microSD Express cards. If the microSD cards you have used for Nintendo Switch do not support microSD Express standards, you cannot use them with Nintendo Switch 2.
What to do when you are short on space
Archive software you are not currently playing
Nintendo’s archive function removes the downloaded software from storage while preserving the game’s HOME Menu icon and its save data. You can download the software again later. This is the least disruptive option when you want to keep a record of the title but do not need it installed today.
Archive enough unused software to bring the available-space figure above the eShop requirement, then return to Data Management and check the number again before buying. Remember that archived software must be downloaded again when you want to play it, so consider your internet connection and future play schedule.
Add a compatible microSD card when you need a larger library
A microSD card is an optional expansion route for downloaded software. It can also store updates, DLC, screenshots and videos, while save data remains in System Memory. Nintendo does not identify one universally correct card capacity: the appropriate amount depends on the games you buy, how many you keep installed and the content you download.

Treat any capacity as a planning decision, not a requirement for every owner. If one or two titles fit after archiving, buying a card may be unnecessary; if you regularly keep many digital games and their additional content installed, expansion can reduce repeated archiving.

Storage limits that are easy to misunderstand
- Save data does not move to microSD. A card expands room for downloadable software and related content, not for copying or relocating game saves.
- The eShop requirement is title-specific. Do not substitute a generic estimate or another game’s size for the figure on the listing you are buying.
- Updates and DLC count toward your plan. Nintendo describes storage needs in terms of the games and content downloaded, so a base installation is not the only consideration when you intend to add content.
- USB hard drives are not a supported expansion method. Nintendo’s Data Management FAQ says external USB hard drives are not currently supported for Switch storage expansion.
- System Memory and microSD space are reported separately. Read both values at the top of Data Management instead of treating them as one interchangeable number.
Common mistakes and how to avoid them
Checking only the console’s built-in space
If a microSD card is installed, ignoring its separate figure can make your available room look smaller than it is. Read both entries. Conversely, do not assume the card can solve a save-data problem; saves remain in System Memory.
Assuming every digital edition is the same size
Download requirements vary by game. Always open the exact eShop product page for the edition you are purchasing and use its stated requirement.
Buying extra storage before checking what you already have
Run the Data Management check first. You may have sufficient room after archiving one or more unused downloads, and Nintendo does not prescribe a single card size for all players.

Planning for the initial download but not later content
If you expect to install updates or DLC, include that content in your storage plan. Nintendo notes that the amount needed depends on the content downloaded, not just the title’s initial listing.

Nintendo Switch, Switch Lite and Switch OLED versus Switch 2
The menu procedure described here is the Nintendo Support procedure for Nintendo Switch, Nintendo Switch Lite and Nintendo Switch OLED. Nintendo publishes a separate storage-check procedure for Nintendo Switch 2, which refers to microSD Express cards.
Do not apply an ordinary original-Switch microSD recommendation to Switch 2. If you own a Switch 2, follow Nintendo’s Switch 2 storage instructions and use the card type specified for that console instead.
A practical pre-purchase checklist
- Identify your console model: Switch, Switch Lite or Switch OLED use the procedure above; Switch 2 has separate guidance.
- Open System Settings > Data Management and note available System Memory.
- Note the separately listed microSD space if a card is inserted.
- Open the exact Nintendo eShop listing for the digital game and record its stated requirement.
- Decide where the download will be stored and confirm that location has enough free space.
- Account for updates, DLC and other downloads you plan to keep.
- If space is insufficient, archive software you do not need now or obtain a compatible microSD card; do not expect a card to store save data.
- Recheck Data Management after archiving or installing a card, then complete the purchase.
Bottom line
The dependable answer to “How do I know if I need to buy extra storage?” is to compare the game’s own Nintendo eShop requirement with the free-space figures in System Settings > Data Management. Buy a compatible microSD card only when your current free space and download plans justify it; otherwise, archiving unused software can provide the room without moving or risking save data.
