Transfer Files from SD Card to Android Phone — Copy, Move, Organise

How to Transfer Files from SD Card to Android Phone

SD cards are slower than internal storage and can't be used for all app data on modern Android. When you want files on fast internal storage — photos, videos, downloads — you need to copy them from the card. AnExplorer makes this painless whether you're using a USB OTG reader, a built-in card slot, or a combination of the two.

Method 1: USB OTG Adapter (Most Phones)

Most modern Android phones support USB OTG (On-the-Go), which means you can attach a USB card reader or flash drive and access it like a drive.

What you need:

• A USB card reader (microSD reader with USB-C is the most common)
• A USB OTG cable or adapter if your reader uses USB-A

Steps:

1. Connect the SD card reader (with card inserted) to your Android phone
2. Open AnExplorer — within a few seconds, the card appears in the left sidebar under USB Storage or External Storage
3. Tap it to browse the card's contents
4. Navigate to the files or folders you want to copy: DCIM/Camera for photos, Music for music files, etc.
5. Long-press the first file to enter selection mode
6. Tap additional files and folders to add them to the selection
7. Tap the Copy button in the toolbar (or Cut if you want to move and delete from the card)
8. Use the back button or sidebar to navigate to your phone's Internal Storage
9. Navigate to the destination folder — or create a new one with the folder+ button
10. Tap Paste — transfer starts immediately with a progress indicator

Selecting entire folders: Long-press a folder (not a file) to select it entirely — subfolders are included. This is the fastest way to migrate a full photo library or music collection.

Method 2: Built-in SD Card Slot

If your phone has a physical microSD slot (common on Samsung Galaxy, Motorola, Nokia, and many budget phones):

1. Insert the microSD card into the slot (usually on the SIM/SD tray using the SIM tool or a pin)
2. Wait for Android to mount it (a notification usually appears)
3. Open AnExplorer — the SD card appears in the sidebar as SD Card or /sdcard2
4. Follow the same copy/paste steps as Method 1 above

Permission prompt on Android 10+: The first time AnExplorer tries to write to the SD card, Android shows a folder access permission dialog — tap Allow to grant access. This is a one-time permission. If you only need to copy TO your internal storage (reading from SD), no special permission is needed beyond the usual storage permission.

Method 3: SD Card in External Adapter > PC > Phone

If neither OTG nor a card slot is available, use your PC temporarily:

1. Insert the SD card into your PC's card reader
2. Start AnExplorer's Device Connect server on your phone: AnExplorer → Device Connect → Start
3. On your PC, browse to http://[phone-IP]:8080 in a browser
4. Upload from your PC to your phone via the browser interface

This is slower but useful when handling very large transfers that benefit from a wired card reader.

What's on Your SD Card? Common Folder Locations

Copy Photos from SD Card — Photo Migration Guide

The most common SD card transfer scenario: cameras use FAT32 microSD cards and dump photos in the DCIM folder structure.

For camera photos (DSLRs, action cams, dashcams):

1. Connect SD card via USB OTG or card slot
2. Open AnExplorer → navigate to the card
3. Go into DCIM/ — inside you'll find folders like 100ANDRO, DCIM_001, etc.
4. Long-press the first folder → tap each additional folder to select them all
5. Tap Copy
6. Navigate to Internal Storage → DCIM (or Pictures if preferred)
7. Tap Paste — all photos and videos copy over

For Android phone camera card: If the SD card was previously in another Android phone:

• Photos are at /DCIM/Camera — exact same location as your current phone
• WhatsApp media is at /Android/media/com.whatsapp/WhatsApp/Media/

Move vs Copy — When to Use Each

Important: Once you Move (Cut + Paste), files are deleted from the SD card after pasting. There is no undo in AnExplorer for file moves, so verify your destination has space before cutting large batches.

Supported SD Card Formats

AnExplorer reads and writes cards in these formats:

• FAT32 — most common legacy format. Works on all Android versions. 4 GB single-file limit.
• exFAT — modern format for large cards (64 GB+). No file size limit. Works on Android 7+.
• NTFS — Windows format. AnExplorer can read NTFS cards; write support depends on device kernel. Best for importing from Windows PCs.
• ext4 — Linux format. Read support only on non-root devices. Full access with root.

If your SD card is formatted as ext4 (rare for consumer cards), you may only see files and not be able to copy with standard permissions.

After the Transfer — What to Do

Once files are on internal storage:

Rescan camera photos: Android's media scanner should pick up new photos automatically, but if they don't appear in your gallery:

• Open AnExplorer → navigate to the new photo folder
• Tap and hold the folder → look for Scan Media or similar option
• Or use AnExplorer's settings to trigger a media rescan

Remove duplication: If you copied (not moved), clean up the SD card afterward:

• Open AnExplorer → navigate to the SD card source folder
• Once you've verified the copies are good, select the originals → Delete

Troubleshooting

SD card doesn't appear in AnExplorer

1. Check that the card is properly inserted (remove and reinsert)
2. Check Android notification area — a "SD Card detected" notification should appear
3. Go to Settings → Storage to see if Android recognises the card but hasn't mounted it
4. Try a different USB OTG adapter (some cheap adapters don't supply power correctly)

"Permission denied" when copying files

• On Android 11+, SD card write access requires explicit folder-level permission
• Open Settings → Privacy → Permission manager → Files and media → AnExplorer and check it has Full access
• Or in AnExplorer: Settings → Storage → select the SD card path and grant access when the system dialog appears

Copy stops partway through

• Check available space on internal storage (AnExplorer shows this in the sidebar storage indicator)
• If copying many GB, the transfer may take time — keep the screen on (disable auto-sleep temporarily)
• Try smaller batches if a single huge copy fails: copy folder by folder rather than the entire card at once

SD card shows wrong file count or missing files

• Some Android security features restrict access to certain SD card paths
• Try granting AnExplorer full access in Settings → Apps → AnExplorer → Permissions → Files and media → Allow management of all files
