Regex - Find in Files.. and remove all files that contain any characters other than letters and numbers

[Stas]

Hello! Please help!

1. I need to delete all files that contain any characters other than letters and numbers.

2. Remove any characters other than letters and numbers in all txt files.

[Stas]

But best of all is the ability to list all the characters that are in some documents. Then remove all these documents or replace these symbols on any others.

@Stas

a regex can modify text but cannot delete files.

You can to this. make a search and replace in all files with Regular Expression:

1. Search [~}{@%.!)\]*(?&$#,=/[^+-]
2. Replace by (leave empty)

This will delete all the special characters from files, and will remain only letters and numbers.
