I am copying data from a file and attempting to print it to a second file. One of the lines of data I want to copy is a path to a folder. C:\ni-rt\NIVeriStand\XNET\Raw Data Logs '\n' and '\N' are escape characters when using fprintf(fid2, mystring) When I open the write file the data looks like
C:
i-rt
Is there a way I can print the string as is to a second file?

The simplest way is not to use the string you want to write as the format string, but as one of the argument to be formatted:
fprintf(fid2, '%s', mystring);
Alternatively, you could escape the '\':
fprintf(fid2, strrep(mystring, '\', '\\'));
Option 1 is more robust and should be faster.
