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.


Mac / *nix Filenames
on Windows


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

What are Mac / *nix / iOS filename characters

The Apple Mac operating system (iOS), along with Unix based systems and some other computer systems, allow characters in filenames that are illegal in the Windows world (these are listed in the table below).

But these files can still be stored on Windows Servers, NAS systems and other storage media that can be accessed by both Windows and Apple computers creating a real headache for System Administrators and Windows users who will see strange characters (typically a dot, a question mark, or a bar) for every character Windows considers illegal.

And, to turn the headache into a migrain some specialized file storage systems will not allow these file names at all.

FileBoss takes the hassle out of working with Mac filenames on Windows systems with the following tools and features.

  • Viewing Mac filenames normally in both Explore and Virtual Folder tabs
  • Viewing Mac filenames using meta-codes for the illegal characters e.g. <?>
  • Searching based on filenames can now include searching for special Mac characters such as the backslash, slash and double quote marks (just to name a few)
  • A quick way to search for all filenames containing Mac characters
  • The ability to convert Mac characters into other characters or strings for Windows Compatibility (or just delete them), either through FileBoss's traditional search and replace renaming routine or a new renaming routine which can replace all Mac characters at once.
  • Mac characters can be replaced (and yes, even added to filenames, if you dare) during inline editing (F2) of filenames.
  • A special renaming routine to remove or change all of these characters at one time.

Viewing Apple / Mac / iOS / nix Filenames

Control how Apple Filenames are displayed

FileBoss displays the special Apple /iOS filename characters in one of three ways. The different views are set using the View > Mac iOS filenames > commands from the main menu.

The default view is the normal Windows view shows the characters as they are shown in Windows Explorer and other file managers - normally as a dot or bar character depending on the system font. All of the special characters are displayed with the same dot or bar so there is no way to tell which is which.

Another FileBoss view is to show the characters as what they actually are, such as an asterisk, backslash or other character.

The third view, the meta view shows the Mac characters between left and right chevrons. For example the backslash would be displayed as <\>. This is useful when entering a Mac Character in a search or when renaming a file, since just entering a bare backslash would not be accepted by Windows (FileBoss does the translation behind the scenes to keep Windows happy).
