…nilla scripts

To use new functions with file system types support, you need to use FSType explicitly

P.S. old exist() function was renamed to GetFileDesc() and new functions were introduced under the exist() name.
To prevent any problems with vanilla scripts, this commit reverts the code to the vanilla behaviour
