This tutorial shows how QCAD can be used on a portable drive or USB stick.
QCAD can be installed or extracted on a portable drive or USB stick without the need to install it on the computers hard drive. This way, it is possible to carry QCAD along on a portable drive and to use it on any computer with an appropriate port and a supported operating system.
To make sure that QCAD stores its configuration on the portable drive, you will have to use the -config command line switch to tell QCAD which directory to use to store the configuration files. You might want to create a Batch or Bash script that does that for you when launching QCAD.
