Need Help Delete Files

[jawaid]

As Salam O Alaekum,
Dosto aksar aisa hota hai ke jab hum koi file delete karte hain to error aajata hai
( Cannot delete abc.mpeg: it is being used by another person or program.
close any programs that might be using the file and try again. )

mere paas aksar yeh error aata hai... PC 10 baar shutdown ho kar open ho chuka hai leqin file delete kio nahi hooti... jab is ka mood ho ga delete ho jayegi warna hoti nahi ... suppose agar movie dekh kar delete karo to yeh msg aata hai leqin aap ne media player bhi close kardo to bhi yeh msg aata hai.. aur kaafi baar shutdown ke baad bhi yeh error kio aata hai... ????
is ka kuch tareeqa bataye is ko kaise delete kia ja sakta hai

aap ke jawab ka muntazir Jawaid Ahmed

waisey main ne 2 topic aur lagaye hain leqin is baar koi reply nahi kar raha.. khair to hai na ? Experts kahan chaley gaye ?
