Solve : trim first 5 characters off of file names?

Answer» <html><body><p>Looking for a way to trim first 5 character places off of a bunch of file names named<br/>01 - filename.mp3 so that the file is trimmed to a name of filename.mp3 without the 01(space)-(space) before the song title.<br/><br/>I saw a program for sale called better file rename for $20, but was <a href="https://interviewquestions.tuteehub.com/tag/wondering-7723068" style="font-weight:bold;" target="_blank" title="Click to know more about WONDERING">WONDERING</a> if anyone knew of a way to do it for free through batch using a read in file name and then trim and rename as filename without the first 5 characters leading into the file name? I dont see why batch wouldnt be able to do it, but this exceeds my batching abilities, so a solution would be a learning experience if you could also describe what does what in the batch.<br/><br/>I have about 3000 <a href="https://interviewquestions.tuteehub.com/tag/songs-239631" style="font-weight:bold;" target="_blank" title="Click to know more about SONGS">SONGS</a> that I want to trim this off of, so I am not sure if there is a way to read in with wildcard *.mp3 for all files in that directory and have it <a href="https://interviewquestions.tuteehub.com/tag/chug-2027578" style="font-weight:bold;" target="_blank" title="Click to know more about CHUG">CHUG</a> through them until they are all renamed without first 5 characters that always start with 01(space)-(space), 02(space)-(space) ect where the leading 2 digits is the track number so maybe ??(space)-(space) can be used as a wildcard type match for the files to test against them, or if the test would be to look for a dash ( - ) at the 4th character place of each file name and if there is a dash at the 4th character place, then trim first 5 character places off of the filename with a read in of that files name, trim, and rename?<br/><br/>Thanks.Try this.  It's not fully tested so instead of renaming the files it will copy them to your %temp% folder from which they can be deleted at will.  When you have tested and proved the script, change the copy line to <br/><strong>ren "!filename!" "!newfilename!"</strong><br/><br/> Code: <a>[Select]</a>echo off<br/>cls<br/>setlocal enabledelayedexpansion <br/><br/>:: Set default directory to the directory containing .mp3 files<br/>pushd path\to\files\|| echo PUSHD <a href="https://interviewquestions.tuteehub.com/tag/failed-2080748" style="font-weight:bold;" target="_blank" title="Click to know more about FAILED">FAILED</a> - job terminated&amp;exit /b<br/><br/>:: Loop thru' a bare directory listing of mp3 files, reading each filename<br/>:: into the environment variable %filename%, creating a new environment<br/>:: variable %newfilename% containing %filename% less the first 5 chars<br/>:: then renaming..<br/><br/>for /f "tokens=*" %%1 in ('dir /b *.mp3') do (<br/>    set filename=%%1<br/>    set newfilename=!filename:~5!<br/>    copy "!filename!"

Note it takes care of variable number of spaces between your numbers, not just 5. COOL!  ... I am going to use this right now to trim up the file names. Thanks!!!For renaming versatility, I cannot recommend a program more than ExplorerXP -- it can trim, stuff, replace and renumber multiple files.<br/><br/>The version I have does not work on vista but is fine on XP (its not been updated on download.com since 2006, so I doubt there will be a new version)<br/><br/>Graham Quote from: gpl on August 23, 2010, 12:33:03 AM<blockquote>For renaming versatility, I cannot recommend a program more than ExplorerXP -- it can trim, stuff, replace and renumber multiple files.<br/></blockquote> there are alot of such kind of software for renaming files.
