[Using programs during free space Wipe Data]

Hi...

I'm new in this foroum... so excuse me if I've posted in wrong place...

 

Last Night I Used 'free space wipe data' for my C drive (my windows drive)... during the process I opened my microsoft office products(microsoft word and excel) which were installed in the drive..

and after opening the programs I faced with this Error: the program has stopped working...

I search about it and realized that I shouldn't use my pc during the progress...

so I have a question...

does it can hurt my C drive files or my microsoft office program or my hard drive?

please help me about this topic....
