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?

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$2" /i 3for /f "delims=" %%i in ('dir /b /a-d *.txt') do ren "%%~i" "%%~ni 1.1%%~xi" If you use the simple for loop without the /f parameter, already renamed files will be again renamed.
Step 1:
Select all files (ctrl + A)
Step 2 :
Then choose rename option
Step 3:
Choose your filename... for ex: myfile
it automatically rename to myfile (01),myfile (02),,.....
If you want to replace spaces & bracket.. continue step 4
Step 4:
Open Windows Powershell from your current folder
Step 5:
For replace empty space to underscore (_)
dir | rename-item -NewName {$_.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(")"),""} 2The below command would do the job.

1I tried pasting Endoro's command (Thanks Endoro) directly into the command prompt to add a prefix to files but encountered an error. Solution was to reduce %% to %, so:
for /f "delims=" %i in ('dir /b /a-d *.*') do ren "%~i" "Service.Enviro.%~ni%~xi" I found the following in a small comment in Supperuser.com:
@JacksOnF1re - New information/technique added to my answer. You can actually delete your Copy of prefix using an obscure forward slash technique: ren "Copy of .txt" "////////"
Of How does the Windows RENAME command interpret wildcards? See in this thread, the answer of dbenham.
My problem was slightly different, I wanted to add a Prefix to the file and remove from the beginning what I don't need. In my case I had several hundred of enumerated files such as:
SKMBT_C36019101512510_001.jpg SKMBT_C36019101512510_002.jpg SKMBT_C36019101512510_003.jpg SKMBT_C36019101512510_004.jpg : : Now I wanted to respectively rename them all to (Album 07 picture #):
A07_P001.jpg A07_P002.jpg A07_P003.jpg A07_P004.jpg : : I did it with a single command line and it worked like charm:
ren "SKMBT_C36019101512510_*.*" "/////////////////A06_P*.*" Note:
- Quoting (
") the"<Name Scheme>"is not an option, it does not work otherwise, in our example:"SKMBT_C36019101512510_*.*"and"/////////////////A06_P*.*"were quoted. - I had to exactly count the number of characters I want to remove and leave space for my new characters: The
A06_Pactually replaced2510_and theSKMBT_C3601910151was removed, by using exactly the number of slashes/////////////////(17 characters). - I recommend copying your files (making a backup), before applying the above.
I was puzzled by this also... didn't like the parentheses that windows puts in when you rename in bulk. In my research I decided to write a script with PowerShell instead. Super easy and worked like a charm. Now I can use it whenever I need to batch process file renaming... which is frequent. I take hundreds of photos and the camera names them IMG1234.JPG etc...
Here is the script I wrote:
# filename: bulk_file_rename.ps1 # by: subcan # PowerShell script to rename multiple files within a folder to a # name that increments without (#) # create counter $int = 1 # ask user for what they want $regex = Read-Host "Regex for files you are looking for? ex. IMG*.JPG " $file_name = Read-Host "What is new file name, without extension? ex. New Image " $extension = Read-Host "What extension do you want? ex. .JPG " # get a total count of the files that meet regex $total = Get-ChildItem -Filter $regex | measure # while loop to rename all files with new name while ($int -le $total.Count) { # diplay where in loop you are Write-Host "within while loop" $int # create variable for concatinated new name - # $int.ToString(000) ensures 3 digit number 001, 010, etc $new_name = $file_name + $int.ToString(000)+$extension # get the first occurance and rename Get-ChildItem -Filter $regex | select -First 1 | Rename-Item -NewName $new_name # display renamed file name Write-Host "Renamed to" $new_name # increment counter $int++ } I hope that this is helpful to someone out there.
subcan
This works for your specific case:
ren file?.txt "file? 1.1.txt"
