ST2 stores nearly all of the interesting files for users under the data directory.
For portable installations, look inside ST2/Data. Here, the ST2 part refers to the directory to which you’ve extracted the contens of the compressed file containing ST2.
Note that only for portable installations does a directory named Data exist. For the other types of installation, the data directory is the location indicated above.
