When working in a station, you often create files of various types in its file space—for example, a Px file if adding a new view, if creating a new Nav file, whenever exporting a view to pdf/txt/csv file, or if making a station backup .dist file. In addition, you often create new station file folders, and also copy graphic image files over to the station’s file space.

Regardless of file types, whenever saving files (or before copying files to the station), we strongly recommend that you restrict all characters in file and folder names to ones in the “original” set of ASCII characters in the BNF for Niagara file paths, namely:

a-z │ A-Z │ 0-9 │ specials

specials= space │ . │ : │ - │ _ │ $ │ + │ ( │ ) │ & │ ‘ │ ’ │ @ │ [ │ ]

Otherwise, use of other characters, for example, a tilde ( ~ ) in file or folder names may result in obscure problems—particularly on JACE platforms (QNX-based hosts). Note that earlier revisions of NiagaraAX automatically restricted file names in dialogs to only the original set of characters above. However, starting in NiagaraAX 3.6.47 and later, these file naming rules were “relaxed” to deal with other issues relating to Web Workbench and locally cached files.
