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.


Converting Mac / iOS/nix Characters

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

Filenames containing iOS/nix characters can be renamed in several ways including inline editing (see: Inline Editing of iOS/nix Filenames) and by using the batch rename routine. To use the batch rename panel use the Actions > Fix Mac/iOS File Names... command from the main menu after selecting the files and or folders that should be processed. You can also use the shortcut key, Ctrl + Alt + X.

How to Convert iOS/nix Characters

Note that this works, as do all the renaming and other action commands, when in Explorer tabs as well as when in virtual folders (search results).

Be careful when just deleting the illegal characters. It is possible that by doing so you will create a name that is the same as another name which didn't have the illegal characters to begin with.

By default, you will have the opportunity to confirm the change in each filename be&fore it is applied.
