Back in Windows 95 OSR2 (I believe), there was a conversion tool that would take your extant FAT16 partition and change it to FAT32 non-destructively (most of the time).
Are there any tools like that now for going from one file system type to another in situ without destroying the data?
Examples: from etx3 to ext4? Or NTFS to XFS?
Answer
For ext3 to ext4 you can use:
tune2fs -O extents,uninit_bg,dir_index /dev/yourfilesystem
followed by:
fsck -pDf /dev/yourfilesystem
To return the system to a consistent state. However, I don't believe (someone correct me if I'm wrong) that this is a complete conversion. I believe there may be an issue with extents...
For FAT to NTFS:
convert (your drive letter here): /fs:ntfs
NTFS to XFS I have no idea but I would doubt it. NTFS is proprietary...
