One question...

How would I find a TARGET project file which contains a certain component?
There is no direct way in TARGET to search for a project with a specific component used.

However, you can use Windows command line to output a BOM (Bill of Material = parts list) as a searchable text file for all projects in the current directory:

for /r %i in (*.T3001) do "C:\Program Files (x86)\ibf\TarV30\professional\TarV30.exe" %i -b

The path in
quotes must of course be adapted to your current version and edition.

The text files *_BOM.txt created from the *.T3001 files by the parameter -b can then be searched with a search tool. By the way: The Windows search for file contents has been unusable for many Windows versions, so we suggest nimble external tools.
