When can we save a file in hard drives?

Hi ,
Denver hope the following steps will guide you in fixing of this issue.:
Hi there ,
It seems you need help regarding storing to the harddrive,
Let me start from basics.
Your computer has two types of memory RAM and Mass storage (Hard drive)
Whenever you work on your PC you are working in RAM . Its a virtual space where you work . But when you turn off the computer everything in it is deleted ot lost.
Whenever you save a file it is automatically gone to harddrive only .
You have seen different drives or drive letter in computer or my computer that is C , D ,E F drives. These are different partitions of your harddrive and this is the place where you can save all the data.
Good luck.
