type nul >> your_file.txt
copy /b filename.ext +,,

The following works through a set of files in a directory and refreshes the date of them.  Useful if your company has a policy for deleting old files automatically, using Powershell.

(ls your-file-name-here).LastWriteTime = Get-Date
Get-ChildItem . * -recurse | ForEach-Object{$_.LastWriteTime = get-date}

If you do this, it may be worth considering time stamping your files: textFile1_20180502.txt for example.
