| NTFS | FAT |
|---|---|
| Default File system In Windows XP, 2k and NT | Fat 16 not compatible with XP, FAT is more |
| Support For Drives over 40gb, Files over GB | compatible with other operating Systems(Windows 95, etc) |
| Allows extended file names, foreign characters | FAT 16 has 8.3 character limitation |
| Has a severely crippled maintenance system in chkdsk Chkdsk is notoriously slow | Has better, more and interactive recovery utilities (scandisk) Scandisk is very quick Just a space for the OS to read files |
| Increased security with file encryption Smaller file clusters, 4kb | Faster on drives less than 10gb FAT 16 cluster size is 32kb |
| Compression to reduce disk space | No |
| User permissions for files and folders | No |
