If you want to overwrite after reading, then do not use QIODevice::ReadWrite
You can, simply do resize(0) before writing

Indeed, which probably callstruncate(). It does not say whether you must thenseek(0)as well, many platforms require seek-when-change-from-read-to-write. It's yet another way. Personally I probably would not open forReadWriteand do that. The OP now has a choice of approaches.
