Most likely your LS already read file and keep track as a processed file.

1. Remove e:\logstash-8.11.1\data\plugins\inputs\file.sincedb\_ce.\*
2. Add line:

```auto
input {
  file{
  	sincedb_path => "NUL"
  	type =>"csv"
...

```

Read [here](https://discuss.elastic.co/t/what-exactly-does-sincedb-path-do/292504/2) about sincedb.

PS. Half of mine post are related to sincedb 😱
