Writing a Conditional Argument Based on Document K-Size...Possible?

Hi everybody,

 

Is it possible for Javascript (JSX) to determine the file size of a particular file, and then conditionally from that point read that value in order to execute a command?

 

Thanks for any feedback.

No need to reinvent the wheel, the following code should provide an example of a conditional based on file size on drive.

 


function main() {
    var folder = Folder.selectDialog("Select Folder");
    var files = folder.getFiles("*jpg");
    var smallFilesFolder = Folder(folder.fsName + "/Folder A");
    if (!smallFilesFolder.exists) {
        smallFilesFolder.create();
    }
    var largeFilesFolder = Folder(folder.fsName + "/Folder B");
    if (!largeFilesFolder.exists) {
        largeFilesFolder.create();
    }
    var len = files.length
    for (var i = 0; i < len; i++) {
        var _file = files[i];
        if (_file instanceof File) {
            if (_file.length <= 200000) { // less than equal to 200 KB
                _file.copy(smallFilesFolder + "/" + _file.name);
            } else if (_file.length > 200000) { // greater than 200 KB
                _file.copy(largeFilesFolder + "/" + _file.name);
            }
            _file.remove();
        }
    }
}

main();​

Also, this would get the active document’s file size

 

var fsize = File(app.activeDocument.path + "/" + app.activeDocument.name).length

if (fsize > 1048576) {
    $.writeln("Active document is larger than 1MB")
    //do something
}

My first question would be; 

 

1) Size on drive

or

2) Size of open file

    To answer your question, file on drive.

      I suppose one could get the length and then use that in if-clauses or a while-clause. 

      var aFile = selectFile(false, "pat")
alert (aFile.length);
////////////////////////////////////
////////////////////////////////////
////////////////////////////////////
////// select file //////
function selectFile (multi) {
if (multi == true) {var theString = "please select files"}
else {var theString = "please select one file"};
if ($.os.search(/windows/i) != -1) {var theFiles = File.openDialog (theString, '*.jpg;*.tif;*.psd;*.png', multi)}
else {var theFiles = File.openDialog (theString, getFiles, multi)};
////// filter files  for mac //////
function getFiles (theFile) {
    if (theFile.name.match(/\.(jpg|tif|psd|png)$/i) || theFile.constructor.name == "Folder") {
        return true
        };
	};
return theFiles
};
