Update May 2017

A May 2017 Microsft security update for Windows 10 conflicted with a major routine in FileBoss resulting in FileBoss not starting on some Windows 10 systems.

Versions V3.101 and later, fix the problem. You can read more about this at the page
Windows Creators Conflict.


Finding Files with iMac / iOS/nix Characters in their Filenames

Please note that this docmentation applies to FileBoss V4 which will be released in September/October 2021

Note that this documentation applies to FileBoss V4 which will be released in August 2021.

There are three ways to find filenames that contain Mac Characters that are illegal under Windows.


Visually inspect the names in an Explorer Tab. This is easiest if the display of Mac characters is set to using Meta-codes. (Use the View > iOS/nix Filenames > Show Meta Tags command from the main menu. See Viewing Mac Filenames for more.)

Standard File Search Routine

Use the Search > Find Files... command from the main menu and then use the Mac Filename Meta-Codes in the search pattern as you would use any other characters. A list of valid Mac Meta-Codes is at the bottom of this page.

Search Dialog for files with names containing Mac characters


Viewing the Results


Three views of Apple Characters


Remember that you can change how the special characters are displayed using the View >  iOS/nix Filenames > commands from the main menu or the icon on the main menu bar. Using the Meta-codes option will make the illegal characters (illegal as far as Windows in concerned that is) more noticeable.



Meta Codes for iOS/nix Specific Characters

Valid Meta-Chars for Apple Filenames are:




Description (used by Windows for)




Used by Windows to separate path elements




Reserved, can be used in some places as a backslash




Wild-card to match any string in searches

Question Mark



Wild-card to match any single character in searches

L. Chevron

R. Chevron

Dbl. Quote

Used internally and by DOS subsystem
