[solved] Copy all files in folder to another directory

ThaRez

Hello
If I know the origin and destination path, let's say c:/org -> d:/trg, how can I copy all the files so that it overwrites those with the same file name ? Thank you!

ps. I'd also be interested in how to remove all the files in a folder... :)

I would iterate on each file in the source directory, get a file, and "copy":http://doc.qt.nokia.com/4.7/qfile.html#copy it on the final path. QFile has also a method remove to delete a file.

QDir has also the "file and folder removing functionality":http://doc.qt.nokia.com/4.7/qdir.html#remove (see also rmdir there).

Hello
Thank you for your reply! I just tried the following:

@QString orgFileName;

foreach (orgFileName, files) // files = qstringlist with file names in folder 
{
    QFile tmpFile&#40;folderPath+orgFileName&#41;; 
    qDebug() << tmpFile.copy(jPath+orgFileName);
    qDebug() << "Copy: " << folderPath+"/UI/"+orgFileName << "To: " << jPath+orgFileName;
}@

But the copy just returns false... Do I need to open/create some file or... ? Thank you!

To remove all files
Qt Code

@
QDir directory("C:/DirectoryPath");
QStringList filesList = directory.entryList(QDir::Files);
QString fileName;
foreach(fileName, fileList)
{
if(directory.remove(fileName))
qDebug() << "Removed: " << fileName;
else
qDebug() << "Not removed";
}
@

To copy look "Look here for Documentation":http://doc.qt.nokia.com/4.7-snapshot/qfile.html#copy

If you want to over write, you can check whether the file already present in the Directory using
@
QDir dir("filePath");
if(!dir.exists("fileName"))
//copy
@

Avoid overwriting, if the file is already there, simply don't copy. If you want to check for File size to see if it is the same file, then "See here":http://doc.qt.nokia.com/4.7-snapshot/qfile.html#size

Now it works, thank you!
