Rename multiple files in cmd

If I have multiple files in a directory and want to append something to their filenames, but not to the extension, how would I do this?

I have tried the following, with test files file1.txt and file2.txt:

ren *.txt *1.1.txt

This renames the files to file1.1.txt and file2.txt1.1.txt

I want the files to be file1 1.1.txt and file2 1.1.txt

Will this be possible from cmd or do I need to have a bat file to do this? What about PowerShell?

Solution 1:

Make sure that there are more ? than there are characters in the longest name:

ren *.txt "???????????????????????????? 1.1.txt"

See How does the Windows RENAME command interpret wildcards? for more info.

For those who like regular expressions, there is JREN.BAT - a hybrid JScript/batch command line utility that will run on any version of Windows from XP forward.

jren "^.*(?=\.)" "$& 1.1" /fm "*.txt"

or

jren "^(.*)(\.txt)$" "$1 1.1$2" /i

Solution 2:

for /f "delims=" %%i in ('dir /b /a-d *.txt') do ren "%%~i" "%%~ni 1.1%%~xi"

If you use the simple for loop without the /f parameter, already renamed files will be again renamed.

Solution 3:

Step 1:

Select all files (ctrl + A)

Step 2 :

Then choose rename option

Step 3:

Choose your filename... for ex: myfile

it automatically rename to myfile (01),myfile (02),,.....

If you want to replace spaces & bracket.. continue step 4

Step 4:

Open Windows Powershell from your current folder

Step 5:

For replace empty space to underscore (_)

 dir | rename-item -NewName {$_.name -replace [Regex]::Escape(" "),"_"}

Step 6:

For replace open bracket

 dir | rename-item -NewName {$_.name -replace [Regex]::Escape("("),""}

For replace close bracket

 dir | rename-item -NewName {$_.name -replace [Regex]::Escape(")"),""}

Solution 4:

The below command would do the job.

forfiles /M *.txt /C "cmd /c rename @file \"@fname 1.1.txt\""
