Here are some of these incommon but very cool features:
FSO features that are rarely understood
GetSpecialFolder Method Returns the path to a specific Windows folder: Windows installation directory; Windows system directory; Windows temporary directory FSO.GetSpecialFolder([0, 1, or 2])
GetTempName Method Returns a randomly generated file or directory name for when temporary data is required
GetAbsolutePathName Method Returns the absolute path to the folder (similar to Server.MapPath).
For example, FSO.GetAbsolutePathName(region) will return a result similar to the following: c:mydocsmyfolder egg
GetExtensionName Method Returns the extension of the last part of the path
(For example: FSO.GetExtensionName(c:docs est.txt) will return txt)
GetBaseName and GetParentFolder Methods Returns the parent folder of the last part of the path
(For example: FSO.GetParentFolder (c:docsmydocs) will return 'docs')
Drives Property Returns a collection of all locally available drives for building resource browser-like user interfaces.
When using the above functions, it is best to create a code for error handling. Because if the required parameters do not exist, troublesome information will be generated.
