Hello @asadjs ,

  1. Use namingFunction to set file’s name used by a file system
  2. Use fileName to set file’s name when it’s being downloaded
3

@dr.dimitru Can you share code for namingFunction?

The code depends on what you want the file to be named on disk and / or on access

’ if (imagefile) {
//var file = e.currentTarget.files[0];
let self = this;
let fileName, fileExtension;
fileName = imagefile.name;
fileExtension = fileName.substr((fileName.lastIndexOf(’.’) + 1));
console.log (fileExtension);
let newFileName = res+’.’+fileExtension
console.log(newFileName);
if (imagefile) {
let uploadInstance = Images.insert({
file: imagefile,
// namingFunction:function(){return newFileName},
meta: {
locator: self.props.fileLocator,
userId: res // Optional, used to check on server for file tampering
},
streams: ‘dynamic’,
chunkSize: ‘dynamic’,
allowWebWorkers: true
}, false)

Since you’re looking at the insert here, you should try number 2 on dr.dimitru’s list.

In your insert method call, just add another attribute named fileName with the name you want the file to have:

        let uploadInstance = Images.insert({
            file: imagefile,
            fileName: newFileName,
            meta: {
                locator: self.props.fileLocator,
                userId: res // Optional, used to check on server for file tampering
            },
            streams: 'dynamic',
            chunkSize: 'dynamic',
            allowWebWorkers: true 
        }, false)

What is the variable res, you define newFileName using it but it isn’t in your code snippet?
