This change fixes the case where the compressed file (e.g. tools.tgz) only contains a folder with the same name (e.g. tools) in its root folder. tools.tgz: |- tools |- fileA.txt |- fileB.txt \- fileC.txt In that case, the "smart" folder creation mechanism will extract the files in a folder "tools", and this extraction folder will contain a single folder with the same name. Before this fix, the tool would try to move out the inside folder to the parent one, but there would already be a folder named "tools", so it would generate a conflict. This change first renames the inside folder to a random string, and only then it is moved outside and the old extraction folder is deleted.
