The QDS file extension is used for Windows Query Directory Search files. These files store saved search queries configured in Windows Server. QDS files can be distributed to reuse searches.
To open a QDS file, first verify if your software is associated properly with this file type. If not, install a program like Microsoft Windows that supports QDS files. Some programs supporting QDS files are Microsoft Windows and Windows Server.
If you have problems opening an unknown QDS file, determine the cause first. To open QDS files, associate the extension with appropriate software in Windows Registry or use a program that already supports this file type. Many files only contain simple text, so try opening in a text editor.
QDS files also store parameters for fractal images in the QuaSZ 3D software. To open QuaSZ Parameter files, use the QuaSZ program. In QuaSZ, go to File > Open and locate the QDS file to open it.
