My windows 7 Drive C partition as RAW file system after disk full.

Thanks for you replay.

I am not able to boot the computer to normal mode but i can boot in recovery mode(which is recommended option).

The commands that i used is;

In recovery mode i opened Command Prompt, there i opened DISKPART, list volumethen  select volume 1(Which is Drive C on my computer) extend.

There after this message appeared "There is not usable free space on the specified disk(s) to extend the volume"

 I even tried to open the Drive C on Command Prompt but still that massage appears. And when i type DISKPARTand list  disk Drive C is not on the list, but when type list volume it is on the list with RAW file system.

You need to remove the hard drive, connect it to another computer as a slave, recover whatever data you can, preferably before you make things worse than they already are.

The situation is that the file system on the drive has been corrupted. You may be able to get data from it using Recuva or similar. After recovering as much as is ever able to be recovered, you will have to start over, installing Windows and all of your programs, none of which will be saved by any recovery program.

Note: In future, never let a drive become so full that it is unworkable, and if you must mess with partitions, use a 3rd party partition manager for the job..

Aomei is a good one, easy to understand and free to download and use..
