<![CDATA[Copying files from qrc suddenly stopped working]]>Hi, I'm trying to copy 2 files from a resource (qrc). It was working fine, untill I changed the path where I was originally copying the files to. I tried changing it back, but that also stopped working. I haven't changed anything anywhere, just the destination path.
Here's what I have:

QString dir = getUserPath() + "/AppData/Local/Temp/Sucharek/";
QDir createTempFolder; createTempFolder.mkdir(dir);

qDebug() << QFile::copy(":/files/drivers.zip", dir + "drivers.zip"); //returns false, the other one too
QFile::copy(":/files/platform-tools.zip", dir + "platform-tools.zip");

I have checked the spelling, the path, tried changing it to a different destination path, still returns false and doesn't work.
Edit: The folder in specified path does exist.

If nothing else is working, did you do a full clean delete and rebuild? Just to make sure the resources are properly compiled into the executable right.

Did you add a prefix or an alias to that file ?

689d89fb-a9fe-4b00-997d-a0901093742f-image.png

I used the non-static version and QFile returned Cannot open :/files/platform-tools.zip for input. Once again, I checked the spelling, paths, they do exist.
The commands I'm using:
QFile file(":/files/platform-tools.zip"); file.copy(dir + "platform-tools.zip"); qDebug() << file.errorString();

Also use the non-static version of QFile::copy() and check the error string afterwards.
