You can use Cleaner to search folders and subfolders and select all the following files/folders:
● SVN repository folders/files
● GIT repository folders/files
● DS_Store files
● .localized files
● Thumbs.db files
● desktop.ini files
● $RECYCLE.BIN folder
In addition to searching for the above files/folders, you can specify your own, e.g. *.bak, *.tmp, etc
Cleaner is full screen friendly and can have multiple search windows open at the same time.
OSX 10.8+ Cleaner now moves files/folders to the Trash. To free up your drive you will need to empty the Trash after use.
