If you have an nfname containing "\c", for instance, "f:\ab\cde\myfile.txt", all command output may display the nfname truncated before the "\c"
e.g. in that example, you''d see "f:\ab" by nfname in listcat, and then no further output.

Warning, escape sequences are executed by the shell at cftutil command time.

You may try using the uppercase CFTUTIL instead, it ensure data protection.

You can also have "sysin" like for the cftutil (cftutil #cftutil_command_file)

if using the CFTUTIL (uppercase one, ensure quote are used for the text set for the NFNAME

To avoid blank contraction when exists in a file name, just ensure the file name is enterred with both double quotes AND single quote
