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.


Add File Times to Filenames

FileBoss makes simple work of renaming files

Whether you want to add sequential numbers, change case, change extensions, remove or convert spaces, add folder names or each file's time to its name FileBoss has a quick and easy routine for doing so. And whether you are renaming files just a few at a time or batch rename by the thousands the routines work exactly the same.

How to add file times to filenames

1) Select the files you want to rename using file times

In the following example we have selected fifteen jpeg files that have just been imported from a digital camera.

2) Select Actions > Rename... from the main menu

Rename menu item on the Actions menu

3) Select the Advanced tab

The display below shows all the tabs used for renaming files. It is important to remember that when the OK button is pressed only the settings in the current tab - in this case the Advanced tab - will be used to rename the files.

1) Click on the Advanced Formatting tab it is not already selected.

2) Specify the format for how the selected files should be renamed. The format codes above, <name> - <created>.<ext> tells FileBoss to:

  • start with the current file's name (<name>),
  • then put a space a dash and another space, ( - ),
  • then write the current file's created time (<created>) - in the format
  • then write a dot (.),
  • and finally write the current extension (<ext>)

3) Specifies the format in which the file time should be written. For a list of formats and how to create new ones click the More Formats help button.

4) The sample format will change as you change the options in the dialog. It gives immediate feedback as to what the renamed files will be.

The above fragment of the Advanced tab only shows the details needed for adding file times to filenames. There are other codes and options in the Advanced rename tab giving complete control over adding sequence numbers and file times when renaming files.

4) Confirm the renamed files

After pressing the OK button in the above step, FileBoss will find the first file to be renamed and display a confirmation dialog similar to the one below.

You can continue to rename or skip each file individually or at any time you can Rename All the rest of the files or Skip Rest thus ending the renaming.

Note that you can edit the new name anyway you like and then press the Rename button giving you total control over how the file is named.

5) See the results of adding file times to filenames

When FileBoss has finished renaming the files the new names will appear immediately in the Contents window.
