how to empty txt-files without deleting them

[Rocky]

Hi,
I have a series of .txt-files (sort of logfiles) in one directory which
should be emptied from time to time, without deleting the files themselves.
Is there a way to automise this?
Thanks!

You can
echo .>filename.txt
to overwrite an existing file to get a file containing a CRLF. Note that you
will get one blank line at the top of the file, and the file size will be
two bytes. If this is a problem, you could create a zero length file, and
copy that over the file you want to truncate. Or, you can look at any number
of scripting options, simple programs, or shareware tools.

Most programs that create .txt files will re-create them
if they aren't present.

If this isn't the case, then you can just copy some blank
files into that directory. Put your blank .txt files in a
new directory, and create a .bat file to copy them to the
directory you want to put them.

Example of the .bat file:

Attrib /s -r c:\ops\*.txt
copy c:\blankfiles\*.txt c:\ops\*.txt
pause


Run this file from a cmd prompt to see what the outcome is.

type nul>filename.txt will create a zero-byte file.

that's it, thanks!
