[JS] rename files without opening in PS

dc-master  schrieb … How can I rename file(s) by script? is there anyway to rename a file without open it in Photoshop? for example: I have these files in a folder: 1Wh-1.jpg 1Cl-3.jpg 1Gy-5.jpg (these names are fix and my Action always save file by these name) and want to rename them to: 1Wh-13005-1.jpg 1Cl-10810-3.jpg 1Gy-10420-5.jpg …

Do you alwas have this three file names?

And do you always want to rename with the same numbers in between?

Or is there a rule for your file names?

eg: [digit][letter[letter][-][digit][.][jpg]

And in which case which number should be pushed in between?

Only a study for more security:

check if your jpg(s) follows this name convention and try (files with other names are not affected):

//var inputFolder = Folder.selectDialog("Select a folder containing .jpg files to process");
var inputFolder = Folder("~/Desktop/TestFolder/Rename");
var aFile = null;
var nameParts = null;
var fileList = inputFolder.getFiles ( /\.jpg$/i );
for ( var i = 0; i < fileList.length; i++ ) {
    aFile = fileList;
    if (aFile.name.match ( /^\d[A-Z][a-z]-\d\./ ) != null ) {
        nameparts = aFile.name.split("-");
        if (nameparts[0].search ( "1Wh" ) != -1) {
            nameparts.splice(1, 0, "13005")
            fileList.rename (nameparts.join("-"));
        };
        if (nameparts[0].search ( "1Cl" ) != -1) {
            nameparts.splice(1, 0, "10810")
            fileList.rename (nameparts.join("-"));
        };
        if (nameparts[0].search ( "1Gy" ) != -1) {
            nameparts.splice(1, 0, "10420")
            fileList.rename (nameparts.join("-"));
        };
    };
};
alert ( 'Done' );

Using Adobe Bridge, it would be similar to my previous reply in the other topic thread:

Re: using top layer name in save as for web and generate file name

However your filename pattern has now changed, so the find/replace would need to be adjusted to use a regular expression… So:

Find: (^.+-)(.+)

Replace: $113005-$2

(there are many valid regular expressions, the example above is very “loose” and if there were always going to be a fixed pattern such as a leading digit followed by two alphabetical then a hyphen then the expression could be made “tighter")

JavaScript can also use Regular Expressions...

Targeting a hard-coded file path/file:

#target photoshop
var aFile = File('~/Desktop/1Wh-1.jpg');  
aFile.rename( aFile.name.replace(/(^.+-)(.+)/, '$113005-$2') );  
alert("File renamed") 

Or using a hard-coded input folder path, filtering on all files with a .jpg extension:

#target photoshop
var inputFolder = Folder ( '~/Desktop/' );  
var fileList = inputFolder.getFiles( '*.jpg' );  
for ( var i = 0; i < fileList.length; i++ ) {  
fileList.rename( fileList.name.replace( /(^.+-)(.+)/, '$113005-$2') );     
};
alert('Matching .jpg files in Desktop folder renamed')

Or using a dialog to select the source folder containing .jpg or .JPG files, rather than hard-coding it:

#target photoshop
var inputFolder = Folder.selectDialog("Select a folder containing .jpg files to process");  
var fileList = inputFolder.getFiles(/\.jpg$/i);  
for ( var i = 0; i < fileList.length; i++ ) {  
fileList.rename( fileList.name.replace( /(^.+-)(.+)/, '$113005-$2') );     
};
alert('Matching .jpg files in target folder renamed')

The .getFiles extension mask can of course be expanded for other file types:

.getFiles(/\.(jpg|tif|psd)$/i);

Or using no file extension mask .getFiles();

I’m still trying to figure out how to create a GUI dialog to populate a variable for the replacement text, rather than hard coding it in.

As far as I know, the only way is to copy the file with a new name, then delete the old file.

var oldFile = new File('/c/myFile.jpg');
oldFile.copy('/c/newFileName.jpg');
oldFile.remove();
