Regex - Find in Files.. and remove all files that contain any characters other than letters and numbers
- 
Hello! Please help!
- 
I need to delete all files that contain any characters other than letters and numbers.

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

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.

You can to this. make a search and replace in all files with Regular Expression:
- Search   
[~}{@%.!)\]*(?&$#,=/[^+-] - Replace by (
leave empty) 
This will delete all the special characters from files, and will remain only letters and numbers.
