 Before we conducted our main study, we changed some stuff from the preliminary:

 All of our studies (almost) were conducted in the Usability Lab in the university. We had 3 different notebooks for our subjects to use, depending on which Operating System they are using at home/work. One Laptop with Windows 10, a Linux Laptop with ubuntu and a Macbook with a rather old Mac OSX (10.4).
 We tested 28 in total with 2 more people missing (will be done this weekend), with a total of 10 Windows user, 10 Mac User and 8(10) Linux User. We counterbalanced the tasksgroups, so we can check if there was a major difference in task completion if people did the “easier” task beforehand and so had the so called “learning effect”.
 The tasks groups: We prepared the folder structure beforehand for the subjects, each task has its own folder, also we counter balanced the order to avoid the learning effect.

 Group A: 8 Tasks on Standard Explorer
 Group B: 8 Tasks on Dual pane
 Group C: 8 Tasks on command line

 For every group of OS (Windows, Linux, Mac) we had different orders, so we can avoid having the learning effect. This will be an important aspect of our analysis.

+** The Process: **
 We started the main study with a round about of our topic, so the subject knows what exactly he is doing and why we are conducting our study. Afterwards he got a data privacy statement, since we recorded the screen they are using and for their insurance of privacy.
 Afterwards we started the interview, asking about some demographical stuff and their multi media knowledge in general. After the introduction the subjects filled in the ATI, a scale which gets a score to the affinity of a person towards technical systems. This score will be used to check if there is a correlation between their ATI Score (basically how or if their technical affinity affects the task completion) and the performance in the user tasks.
 The user tasks were conducted right after and depending on the knowledge of CLI (we asked beforehand if the person knows the CLI and how experienced he/she is with it), we gave them a short introduction how to use a CLI and explained shortly how the commands are used and which shortcuts are commonly (tab for autocomplete, arrow key to repeat a command…). Depending on the OS and subject, we changed the order of tasks groups (counter balancing) to avoid the learning effect. The duration of one user study last from 50 minutes (fastest) to 2,5 hours (slowest).
 As conclusion we asked the subjects some questions about the used file manager and some questions about esthetics (check “After User Tasks”).
 What we found out (without doing the evaluation and analysis yet):
 •	The normal Windows user are usually more used to the User Interfaces and functionality
 •	Linux User are commonly more used to the Terminal than the other 2
