Because the 4g sd card on your hand is only used as a USB flash drive, you don't need to consider the format of your mobile phone. You just want to format it into NTFS format. Needless to say, the advantages of the NTFS format can be used to automatically compress files (virtually increasing space), encrypt files, Set permissions, and so on. Here are a lot of details about the specific search.
However, there is not much information on whether the SD card can be formatted into the NTFS format on the Internet. I have tried to format the USB flash disk into the NTFS format before. There is no problem if you want to use the SD card.
Insert the SD card to the USB interface of the computer through the card reader. In the resource manager, right-click the SD card and format it. However, there is only FAT32 (card is the new standard sdhccard), and no other format can be selected. It seems that this mission cannot be fulfilled in the graphic interface.
Go to the command line mode and start -- <remote -- <cmd -- <press enter to open the black command line interface.
Run the "K: \ <format K:/Fs: NTFS/V: 4g_ntfs/C/X" command. The "K" is the drive letter: "The disk is formatted as NTFS, and the volume is marked as" 4g_ntfs ". compression is used. If necessary, force remove other occupied files.
After you press enter, the following message is displayed:
Insert a new disk in drive K:
After the preparation is complete, press enter...
Press enter and prompt:
The device optimized for deletion does not support the NTFS file system.
To change the device optimization method, select the "Policies" tab on the properties page of the device.
Oh! No. Follow the prompts, double-click the delete device icon in the lower right corner, select the display device, and then select the Property setting policy of "generic storage device USB device" (which may display some differences, change the "optimize for rapid deletion (r)" of "Write cache and secure deletion" to "optimize for performance (p)" below )". After you click OK, the system prompts you to restart.
Note that: Double-click the icon by default.
Click attribute display at this time
You can see that there is no "policy" item mentioned in the prompt, so double-click the icon and check it.
Then, click Properties:
Use the following command: "K: \ <format K:/Fs: NTFS/V: 4g_ntfs/C/X:
The file system type is FAT32.
The new file system is NTFS.

No problem at all. Try to copy some files into the SD card and everything works. In this way, the SD card is formatted into the NTFS format to improve security and increase the available space in a certain program, although not a lot.
