If you’re asking how to set an SD card as the default storage on a Samsung tablet, there’s no system-wide setting for that. Samsung Android devices don’t support converting a removable microSD card into internal storage. If your Galaxy tablet supports microSD, you can still use a card for files and media, and move some apps when their settings allow it.
Check that your Galaxy tablet supports a microSD card
Not every Samsung tablet has a microSD slot. Check the specifications for your exact model to confirm that it supports cards and to find its maximum supported capacity. Samsung notes that screens and settings can vary by model, carrier, and software version, so don’t assume another Galaxy tablet’s instructions or capacity limit will apply to yours.

Samsung’s card-format overview lists microSD cards at up to 2 GB, microSDHC cards at over 2 GB up to 32 GB, and microSDXC cards at over 32 GB up to 2 TB. Those are format ranges, not a promise that a particular tablet supports a card of that size. Samsung recommends microSDXC for high-resolution video; confirm your tablet’s specifications and choose a compatible card for your intended use. Samsung Support: microSD card information
Move photos, videos, and other files to the card
Use Samsung’s My Files app to move or copy files. Samsung directs users to My Files rather than moving files directly from apps such as Gallery. A move frees space on the tablet; a copy leaves the original in place.

The SD card destination appears only when compatible storage is available. For Samsung’s file-management guidance, see how to use an SD card or memory card.
Move an app only if its settings allow it
Some apps can be moved to removable storage, but the option is not available for every app. On a supported tablet, open Settings > Apps, select the app, tap Storage > Change, choose SD card, then tap Move. If Change is missing, the app’s storage location cannot be changed. Preloaded apps and apps whose developers disallow removable storage are common exclusions. Don’t assume that all app data or future updates will reside on the card. Samsung Support: manage and transfer data with a memory card

Choose the right removable-storage option
| Option | Best for | Check before using |
|---|---|---|
| microSD card | Keeping files and media on removable storage in a tablet with a card slot | Confirm the tablet has a slot and check its model-specific capacity limit. Choose a card suited to the files you plan to store, especially high-resolution video. |
| USB flash drive or other external storage | Transferring or backing up files, including on a tablet without a microSD slot | Confirm the tablet supports the connection and whether a compatible OTG adapter is needed. External storage is not a default internal destination. |
Samsung also documents using external storage with Smart Switch to back up and restore selected content when the devices and connections support it. See Samsung Smart Switch guidance.
Format or remove a card safely
Back up anything you need before formatting: formatting erases the card. On supported software versions, Samsung’s route is Settings > Battery and device care or Device care > Storage; switch to the SD card view, open More options, then choose Format. Menu names and availability vary. Before removing a card, unmount it in Storage settings if your tablet offers that option. If card errors continue after formatting, Samsung advises replacing the card; card problems can cause data loss and performance issues. See Samsung’s microSD troubleshooting guidance.
