Try Power shell
And Run this in your desired directory
gci *.txt | rename-item -newname { [string]($_.name).substring(1) }
Explanation: - gci *.txt collects all *.txt-files in the actual directory.
- rename-item -newname renames the piped results from the gci-command with the string that is generated in {}
- string.substring(1) takes the filename starting after the first character
When you want to remove the first Two characters, just replace the (1) after 'substring' with (2). In power shell, the whole filename is treated as a string(-object), points included.
