All those new files have to be output to the same, new directory.
So my problems are (I tried different things without success):
- how do I get the names of the subdirectories, so that I could use them as the new filenames?
- how do I loop through those subdirectories? (I guess I could use a workspace-runner, but then I would have to get the names of the subdirectories first > could this be done with the Schema-Reader...?)
Thanks in advance

Mosaic your tifs with a group-by on path_rootname and use the same as a fanout on the tif writer.
Basically same as JDH's approach, but I would use the FilenamePartExtractor transformer to extract subdirectory name.
(1) Select the root directory for the Dataset of the TIFF Reader using the Advanced Browser, so that the reader reads every tiff file in the root/subdirectories.
(2) Expose "fme_dataset" in the TIFF Reader Feature Type Properties dialog > Format Attributes tab page. The "fme_dataset" will store full path of each tiff file.
(3) Add a FilenamePartExtractor and set "fme_datset" to the "Source Filename" parameter. The Folder Name Attribute (named "_dirname" by default) will be added to the feature, which stores the subdirectory name.
(4) Add a RasterMosaicker and set "_dirname" to the "Group By" parameter.
(5) Use "_dirname" as the Fanout Attribute for the TIFF Writer Feature Type, so that the resulting tiff file name will be the "_dirname" (subdirectory name).

thanks a lot for your detailled answer. It works perfectly!
(To get all the resulting files into the same directory, I had to set the fanout dataset parameter for the writer (navigator: advanced > parameter) to "no")
