Very simple question here.

I'm implementing a process whereby I need to ask an operator to change both
the name and format of a file. The format must change from .csv to .txt

If i ask them to simply change the file extension while changing the name
rather than opening the file save as etc. is there any possibility of a
loss of data integrity?

The .csv file will contain a list of 32 alphanumeric characters separated
into 8 blocks of 4 by 7 dashes €œ-€œ.

Having tested this with a some codes and it seems to work fine. I just want
to make sure that I have all bases covered as these codes are business
critical and my job wouldnt be worth getting this one wrong!

Any input you have would be greatly appreciated!
