If your SD card appears empty in Windows 10 or 11, but the storage space shows used, your files may be hidden. In this guide, we will show you how to show hidden files on SD cards in Windows and recover lost files using iCare Recovery Free (Windows).
Hidden files on SD cards often occur due to:
Before attempting recovery, always try Windows’ built-in methods.

If your files are still missing after recovery attempts, they may simply be hidden due to corrupted file attributes or malware activity. You can use the Windows Command Prompt to restore their visibility by resetting file attributes.
attrib -h -r -s /s /d E:\*.*
This command works by modifying the metadata attributes stored in the file system (FAT32, exFAT, or NTFS) that determine how files behave and whether they are visible in File Explorer.
When executed, Windows will traverse the entire SD card, updating the file attribute table for each file and folder. This is especially useful if files were hidden by a virus or by accidental attribute changes, since the attrib command directly interacts with the file system’s attribute bits instead of relying on File Explorer settings.
After the process completes, open your SD card in File Explorer and check if the missing files are now visible. If they still do not appear, it could indicate deeper file system corruption or data deletion that requires specialized recovery tools like iCare Recovery Free, TestDisk or PhotoRec.
Each file in Windows has a set of binary flags in its metadata that define how the operating system treats it. These attributes are stored in the file system itself—either in the File Allocation Table (FAT) or the Master File Table (MFT) for NTFS volumes. Common attribute bits include:
When a virus or malfunctioning software hides your files, it often does so by toggling the Hidden and System bits. The attrib command reverses these flags at the file system level, restoring normal visibility and access permissions without altering the actual data content of the files.
Understanding these attributes is helpful for diagnosing visibility and access issues, especially on removable drives where file system metadata can easily become corrupted.
Some viruses hide files on SD cards. Run a trusted antivirus scan on your SD card to detect malware. After cleaning, repeat the steps above to reveal hidden files.
If your files still do not appear or were accidentally deleted/formatted, or when SD card turns RAW, iCare Recovery Free is a safe tool to restore them:
