Copying CSV file from linux to pendrive causes format change how to fix it ?

[Ramkumar Mohan]

This is my Code ,

const QString srcPath = QFileDialog::getOpenFileName(this, "Source file", "/home/pi/git/build-UI-Desktop-Debug/",  "csv files (*.csv)");
if (srcPath.isNull())
    return false;
QString name = "Data.csv";
QString dstPath = QFileDialog::getSaveFileName(this, "Destination file", "/media/pi/"  + name, "All files (*.*)"); 
if (dstPath.isNull())
    return false;

if (QFile::exists(dstPath))
    if (!QFile::remove(dstPath))
        return false;

return QFile::copy(srcPath, dstPath);

Output :-

What is a "format change"?

What did the user enter as source & destination file names/paths? How do we know where/what the file you show in the screenshot is?

QFile::copy() should just do a copy. Have you checked a byte-by-byte comparison tool to see if the source & destination files are identical?

This looks to me like the copy is still in progress. Maybe its a very large file and you need to give it some time to complete.

Surely the OP would have allowed for that before posting?! :)
