Convert windows drive or disk file system from FAT32 to NTFS without losing data

Hi all,

I had a problem with my external hard disk when copying some 25GB file.

I had troubleshoot the problem and understand that, my hard disk file system is FAT32, which can only copy max 4GB single file size


I was thinking without losing my data, how can I change the file system, so that, I copy more than 4GB sized single files

Then I come across the following commands in Windows

1) chkdsk : Check disk

2) convert : Convert disk file system


chkdsk command


cmd> chkdsk volume_letter: [options]


Checks for disk errors and fix it

cmd> chkdsk I: /f


convert command


cmd> convert volume_letter: FS:NTFS [options]


Convert volume from FAT to NTFS in verbose

cmd> convert I: /FS:NTFS /V


Possible Errors with solutions

Insufficient Memory


Nearly 4 GB files in existing FAT32 system


Move the files to local drive, do chkdsk and then convert
