Question / Problem
I downloaded and installed TreeSize Free and now there are other programs installed as well.
Answer / Solution
The official installer for TreeSize Free (as well as the portable version and the version available in the Windows Store) would not install any other applicationand is tested to contain no malware, adware, or similar.
Please assure to download TreeSize Free from trusted sources only, like our official download server at https://www.jam-software.com/treesize_free
