I need to save some engineering files that need the thicknesses in the filename. Windows hates "/" or "", so I can't use a simple fraction. Symbols like this...

⅓, ⅔, ⅕, ⅖, ⅗, ⅘, ⅙, ⅚, ⅛, ⅜, ⅝, ⅞

...are nice, but don't cover the full gamitt of dimensions (ie. 1/16").

In addition, Windows hates " in the filename, so I assume in is used instead?
