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.

The current download, V3.101, fixes the problem. You can read more about this at the page
Windows Creators Conflict.


Converting iOS/nix Characters

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 > Rename... command from the main menu (or click the Rename button on the Actions menu) and then select the Convert Mac Filenames panel from the list on the left as shown below.

How to Convert iOS/nix Characters

Select the folder (or folders) at the start of the structure to copy

Select the folder in the Contents window. Below the S:\Shakespeare\Plays folder has been selected.

Rename Panel of the Rename Files Dilaog

You can enter a single character or a string of up to ten characters to replace each special Mac Character that is enabled. Alternately check the delete box to remove the character without replacing it.
