Create a package using the option "Projet translation memory" (last screen). Within the project settings select file-based TM.

I see no such option.

On the last screen in Studio 2011 I have:

New project TM for each package

Existing project TM for each package

No project TM in the package

I selected "New project TM for each package". There is no existing project TM since we don't use project TMs internally, only one main server-based TM.

Thank you for your help!

OK, I do not have server based TMs here. What you can do is to create a Project TM via batch task (Project - Batch tasks). In this process you should be able to chose a file-based tm.

OK, I just want to make sure, that this newly created project TM inside the package contains all the data from our server-based master TM.

If it does, then why only 2,5 MB instead of 25 MB?

A project TM never contains the full data of a master TM. The purpose of project TM is to create a translation memory, which contains exactly the segments from the main TM, which are needed for the particular project.

You can check the package (it is a zip container, so you can open it with WinZIP or similar - or just add ZIP as file name extension and open in Windows), if there is a TM folder and what kind of TM is enclosed there.

When creating a project TM the minimum match value and the number of hit settings in the TM settings within the project settings are relevant. With 70/5 you get a number of units in your project TM. If you change the settings to for example 40/9, the number of units will be more than two times bigger.
