# Remove last few characters of a folder name

Posted on 2013-02-07

I found this script on this website to remove the last few characters of a file name but I was wondering if the same could be done for a folder name:

@echo off
setlocal enabledelayedexpansion

for %%F in (*.docx) do (
set fn=%%~nF
ren  "%%F"  "!fn:~0,-4!%%~xF"
)

Can it be changed to check a folder and rename all the sub folders by removing the last 7 characters?

Thank you.

Yes, this would do what you wanted.  Typically folders don't have extensions, if that isn't trrue in your case let me know and we can adjust.  Change the folder name in the PUSHD to match the root folder you want to search for subfolders in.

@echo off
setlocal enabledelayedexpansion

pushd "c:\temp"

for /D %%F in (*) do (
set fn=%%~nF
ren "%%~F" "!fn:~0,-4!
)

Thank you for your response.  I have folders with foldernames like below:

folder1_folder_12345678_1234567
folder2_folder_98765432_9876543
folder3_folder_12345321_8765348

When I run the script above it returns:

folder1_folder_1234
folder2_folder_9876
folder3_folder_8765

It seems to be erasing more than 7 characters.  Any ideas?

Thank you.

BP,

If I add 'echo' to the script it shows the rename of the folders correctly.  I can change the # 7, 8, 9 or 10 characters and it shows the rename correctly.  Once I remove the 'echo' it erases more than the # of characters.

@echo off
setlocal enabledelayedexpansion

pushd "c:\temp"

for /D %%F in (*) do (
set fn=%%~nF
echo  ren "%%~F" "!fn:~0,-4!
)

Looks like I lost a double quote along the way, try changing:

echo  ren "%%~F" "!fn:~0,-4!

to

echo  ren "%%~F" "!fn:~0,-4!"

BP,

I tried that and when I use echo it returns the correct folder name.  Once I take the echo out, I receive this message "a duplicate file name exists, or the file cannot be found".  Right after that almost the whole file name gets erased.

Thank you.

Wht is the file name causing a problem, does it have any special characters in it (non alphabetic)?

All the folders have underscores in them and commas.

Folder1_test_20130208_1234567
Folder2_test_20130208_1234987
Folder3_folder_02130208_9876543
Test,test1_02130208_1234876

Can be named like that. Different names, all have the date in them.

Odd, I ran the test here, and it worked as expected.  See the logging below.

BP,

Thank you.  Sorry, yes it is working correctly.  What I didn't notice is that there can be folders like below:

FOLDER_FOLDER1_20130210_1234567
FOLDER_FOLDER1_20130210_9876543

When the script runs it does what it is suppose to and removed the last 7 characters and prompts that there is a duplicate name because once the last 7 are removed those folders would be identical.

I am not sure how to handle that.

Thank you

If you can come up with the logic that you want when a duplicate occurs we can try to add that to the script.  Should really have it in there since dupes can occur.  Would you want to add something to the end?  Or just flag as a problem? Etc.

What if there were duplicates could you leave 1 character, delete 6 instead of 7 characters. Or add a number 1 to it?

Would that be difficult?

Anything would work.

I see you closed this question (thanks for the feedback).  If you still want help with the duplicate problem, post as another question, link it to this one, and I'll work something up.
