If you want to validate a supplied folder:
The best way is using the control event (not custom action!) SetTargetPath, when the supplied path does not qualify, a suitable message is shown and all remaining control events are skipped.
SetTargetPath checks for many properties, eg. not existing drives, valid characters, read-only folders, volumes without support for long file names, etc.
If you're just after a name to be used for a file:
In the temp folder, create a unique folder, in that folder try creating a file with the supplied name.
