_GANTRY
"c:\GetTT"

_SNOWBALL
"c:\GetSnowball"

_TT
"c:\GetActivity"

_APP_PATH
"c:\windows\desktop\CreateAct"


I don't know whether I should add the txt file names like:"c:\GetSnowball\snow_3.txt" bcoz in GetSnowball folder, 
there might be other txt files in it(eg snow_w.txt). But only one txt file will b there at a time.
