Add a line of content into .txt file.

nguyenthinhvt95 — Mon, 10 Mar 2025 04:49:03 GMT

I have a problem need your help:

I create a txt file to count how many file export per month to report to boss.

the structure of content line in .txt file (show in the picture):

"Number count" , "Path project" , "extra infomation".

At the moment I use foreach funtions to reach all line of .txt file and then use token by "," to get the final number.

It working well but it take really a long time to reach all line of .txt.

Is there any function that allows adding a new line of content to a TXT file, with the requirement that the added line must be on a new line compared to the existing content in the TXT?"

if oyu whant to append text to a file you use this:

string $filepath = "C:\test.txt" string $txttoappend = "This should be added to the file as new line" FILE OPEN $filepath FOR APPEND AS output FILE WRITE $txttoappend TO output FILE CLOSE output

if reading and handle entries in that file is to slow in the powermill macro language consider using a simple C# application.

Hi @icse

You are right, I use method cmd to create a new .txt file and then I append this to the main txt file. This really fast.

Thank you for a suggestion.
