use Drag and drop file as /f findstr

Question

Im trying to write a script where users can drag and drop a *.txt or blank extension file for the /F file list search string any suggestions?

This is all that I have so far.

@echo off 
for /F %%i in (*.) do (
  echo searching for %%i 
  Findstr  /s /I /n   "%%i" *.txt >>\\myourput.csv
)

Answer 1

for /F %%i in (%*) do (

%* stands for "all parameters" (if you drag one or more files to the batchfile, the batchfile will run with those file(s) as parameters)

Use %1 to use the first parameter only.
