If you want to do this from within a batch (. When typed directly into the Command Prompt ( CMD.EXE). So you can recursively rename files to lowercase with this command: for /f "Tokens=*" %f in ('dir /l/b/a-d/s') do (move /y "%f" "%f")īecause it turns out that Move can cope with directory paths. ![]() Note this batch is written to run from the folder containing the files you want to rename. ![]() … you cannot specify a new drive or path for your destination file. If a machine wrote these files and each and every one one is formatted exactly alike (ending in 9 characters of underscore + date in your example), you might be able to get along with an ordinary batch file. To make it recursive, but it doesn’t work,Īllows you to specify a drive and path with filename1 (the source),įilename2 (the destination) must be just a filename. Sawny suggested a simple modification to loftysnake’s answer If a given filename is not modified by the expression, it will not be renamed. The perlexpr argument is a Perl expression which is expected to modify the string in Perl for at least some of the filenames specified. (3) Removing the BOM: right, easy, depending on your goals. DESCRIPTION 'rename' renames the filenames supplied according to the rule specified as the first argument. Place it as second line, and it will give you an error message about the BOM at the first line but will execute the second line normally. Works for the current directory but does not search subfolders. Place echo as first line of the batch file and run it, it will not work. The accepted answer to this question, by loftysnake, If /i "%folder:~0,1%" NEQ "d" LwrCase_Folder - %1 is NOT a folder.&endlocal&goto :EOFįor /f "Tokens=*" %%f in ('dir %sw%') do ( If not exist %1 LwrCase_Folder - %1 NOT found.&goto :EOF If Syntax: LwrCase_Folder FullyQualifiedDirectoryName&goto :EOF NOTE: LwrCase.bat makes use the the /L switch of the DIR command, which returns lower case names. Where FullyQualifiedDirectoryName is the fully qualify folder path, and /S is an optional parameter that will also rename files names in all sub-folders. To rename all the files names in a directory, use: LwrCase_Folder FullyQualifiedDirectoryName Where FullyQualifiedFileName is the fully qualified file name to be renamed. ![]() To rename a file name to lower case, use: LwrCase FullyQualifiedFileName Using only standard commands, I have scripted LwrCase.bat and LwrCase_Folder.bat, to rename a file name to lower case, or rename all file names in a folder to lower case.
