I want to ask how to convert from FAT32 to NTFS in Windows without losing data on the conversion? And i have read a few article about conversion and it should do in Command Prompt with code

CONVERT C: /FS:NTFS

But i'm not sure if i do that my data wont lose. so anyone who had an experience in this before???

A concise, practical addendum to the thread (for and others): the Windows CONVERT utility does perform an in-place FAT/FAT32 → NTFS conversion and normally preserves files, but it’s not risk‑free and the change is one‑way (to go back you must reformat). Treat the command as a sensitive operation and plan accordingly. (learn.microsoft.com)

Concrete prep and troubleshooting to add to earlier posts: run a full disk check to repair errors and bad sectors before converting (example), and confirm plenty of free space — conversion can fail with “Insufficient Memory” or “Insufficient disk space” if the system has low RAM, the volume has bad sectors, or very large single files are present. If conversion fails, the safest recovery path is using the backup you made, reformatting as NTFS, then restoring files. (itprotoday.com)

If you want to reduce post‑conversion fragmentation of NTFS metadata, create a contiguous placeholder file for the Master File Table and then let the converter use it (this is an advanced option). Example placeholder creation (adjust path/size to suit number of files):

fsutil file createnew D:\cvtarea.bin 104857600

(That placeholder is then specified to CONVERT via the /cvtarea option; see Microsoft docs for details and exact sizing guidance.) Also note CONVERT will offer to schedule the operation at reboot if the volume is in use, and converted boot volumes may receive default NTFS permissions. (learn.microsoft.com)

Final notes: and were right to flag disk checks and backups; is correct that most conversions complete without data loss — but the real issues are damaged files, low RAM, full volumes, or bad sectors. For removable/bootable media or when conversion repeatedly fails, copying off, formatting to NTFS, then copying back (or using a reliable partition tool) is often faster and safer. (howtogeek.com)

hi, i have never tried it myself ,but just want to say as with anything we do like this on a computer its always recommended to backup ones data anyway .so at worse all you loose is windows and programs if something goes wrong.also just read this todo before the convert .
Completely defrag, and scandisk your machine. Then, open a command prompt (Start->Run, type in "cmd" in the box and hit "Ok"), and then type:CONVERT C: /FS:NTFS

before you do that format using convert c: /fs:ntfs try to back up first your data, so that if you missed it you have already a back up data...
