I received another big 2 txt files - sizes of 1.5 and 12GB.
The first one I am able to open in the TextPad and convert to DOS (Tools-> Convert to DOS). Then I am able to work wit it.
With the other one there's no much I can do.
I cannot open it with anything, thus I cannot convert it to dos (the files are probably coming from IBM AS400 system or Unix).
Is there any way on how to write a simple vbscript or enter a dos command which would help to convert that big file into a usable dos format?
