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.


Changing Case of Filenames

Or to upper case, lower case or even first caps!

A webmaster had to move several sites from a Windows based server to Linux. In the process she wanted to reduce all filenames to lower case to reduce problems with Linux's case-sensitive conventions.

She used FileBoss' Quick Set renaming panel to quickly set thousands of filenames to lower case.

First Create a File Set if Necessary

   If all the files you want to change are in one folder display that folder in an Explore View and go straight to Select the Files to be Copied.


   Click here to see how to create a File Set.

   Remember that you can save File Set definitions for later use making it easy and quick to repeat this operation another time.

Second Select the Files to be Changed

   Use any of FileBoss' advanced selection methods to pick the files you want to change. From simply selecting 'All' to selecting by almost any criteria you can think of FileBoss will make this step really easy.

   Click here find out more about selecting files and folders.

Third Set the Case of the Filenames

   Use the Actions > Rename... command from the main menu

   or press Ctrl+R

The Rename dialog will appear

   Select the 'Quick Sets' tab across the top.

   In the Name and Extension groups select whether you want to set the names to Lower Case, Upper Case, Word Cap or No Change.

   Click OK and you will be able to either confirm or skip each file or have FileBoss rename all selected files without pause.
