The floppies i buy have 1.44MB as the capacity mentioned but in windows the capacity is shown as 1.38MB. Why is it so.

Because there are two system files which are normally not displayed on every disk:

The files are MSDOS.sys and IO.sys both are about 37Kb big so if you add them up and add that to a disk's capacity you get aproximately the 1.44Mb you're expecting. Just type chkdsk a: at the DOS prompt and you get something like this

E:\>chkdsk a:
El tipo del sistema de archivos es FAT.
Volumen ROMPAQ creado el 27/07/2000 a las 12:00
El n?mero de serie del volumen es 1F51-17EB

512 bytes en cada unidad de asignaci?n.
2.847 unidades de asignaci?n en disco en total.
2.456 unidades de asignaci?n disponibles en disco.

Even though thetext is in Spanish you get the idea, right? :)

As a side comment, if you format a floppy in DOS 6.22 or earlier, you get the full 1.44MB.

The lost space started with Windows 95.
