i change file names before backup
some days 10, some days +100 files changing with order

using fast file renamer program. but that program very simple. dont understand file-name and file-ext type

if possible, will be good before backup

Test this: < and > are not legal in a filename so I ignored that.

Some lines are repeated to cater for MULTIPLE repeating . and - characters
It only shows the command on the screen, so remove the `echo` to make it work.

Code: [Select]echo off
for /f "DELIMS=" %%a in ('dir *.xls *.xlsx *.doc *.docx *.txt *.pdf *.log *.dat /a:-d /o:n /b') do call :next "%%a"
pause
GOTO:EOF
:next
set "newname=%~nx1"

set "newname=%newname:,= %"
set "newname=%newname:)=%"
set "newname=%newname:(=%"
set "newname=%newname:!=%"
set "newname=%newname:..=.%"
set "newname=%newname:..=.%"
set "newname=%newname:..=.%"
set "newname=%newname:..=.%"
set "newname=%newname:..=.%"
set "newname=%newname:--=-%"
set "newname=%newname:--=-%"
set "newname=%newname:--=-%"
set "newname=%newname:--=-%"
set "newname=%newname:--=-%"

echo ren %1 "%newname%
