You have a pen-drive or probably an external hard drive that currently has FAT32 file system and you want to change it to NTFS, because FAT32 does not support to handling large files(over 4GB).Like now you going to copy one single file it size was more then 4GB means you get one error message "The file is too large" or "Not enough disk space error"despite disk space being available.
Important Note:While this method works perfectly, I would still advise you to backup your data in case anything goes wrong.
FAT32 to NTFS Conversion Steps
1) Open Command Prompt (cmd).
2) Type "chkdsk g: /f" (without quotes) enter, Where G is the letter of the drive to under conversion.
This checks the drive for error and fixes them automatically.
3) Type "convert G: /FS:NTFS" (without quotes) enter,G is again the letter of the drive to be converted.
The command prompt will start the conversion process and after a few minutes, CMD will say that conversion was successful.
Now you can check it in the properties of the drive it changed NTFS format.
I convert my USB drive using this steps and it worked now i can able to coping the more then 4GB files. Make it Simple
