First, add the files whose file names you want to shorten to the list. You should not use the folder selection
dialog "Add --> Folder". Instead add the parent folder(s) of the problem causing files by dragging and dropping
them onto the program interface. As type to be imported, you can specify on request:"Read files and folders"
as well as "Include all sub-folders".
The maximum number of 260 characters fully supported by Windows refers to the entire path
(drive letter: \Folder 1\Folder 2\... \File name.extension) and not just the name, so it is important to add all parent folders
with very long names. Alternatively, you can shorten the folder names first and subsequently the file names. This is
particularly recommended if the folder structure to be processed is very extensive. In this case, define the type to be
imported as "Read folders only" and "Include all sub-folders".
To improve the clarity of the current and new status of the name length, it is also helpful to display the following columns
in the preview list:
To do this, click on the menu "List" and select the menu item "Customize columns...".
Rename Expert allows you to filter files to target only those files that contain too many
character in the file name. Set, as shown in the figure, the maximum number of allowed
characters in the path or file name and the program only shows only those files that matches
the filter criterion in the preview list.
Click on the button featuring the "Plus" symbol to add the action "Other --> Shorten names" to the action list.
The picture shows the default configuration of the action. Folder and file names are limited to 64 characters. This
setting is optional and can be changed at will. The option "Short file names individually to reach a path length
of x characters" limits all file names to the set number of characters, depending on the total path length. This
allows files from folders with fewer characters in the name to retain a longer name. The minimum length of the new
file names can also be set.
Click on the button featuring the plus (+) symbol to add the action Remove to the action list.
The next step is to set the maximum number of characters allowed in file names. The settings shown in
the figure would shorten all file names to 32 characters. File names which are already shorter than this length
will remain unchanged.
To do this, select the Rename Function "Remove --> an area --> defined by character type"
and make the settings shown in the illustration. Thereby, in this case, the file names will be
limited to a maximum length of three words or groups of digits.
In the preview list, a preview of the new name of the file is displayed in real time. Potential conflicts
such as duplicate file names, caused by the shortening, will be highlighted in red color and can be solved
for example by the additional insertion of a conditional numbering at the end of the filename. Using the
conditional numbering, a number is automatically inserted at the desired position (e.g., at the end of the
file name), if the new file name is already taken by another new file name or a file with that name already
If there are no conflicts, the Tasks dialog can now be opened by clicking on the Apply
button. All files to be renamed are listed there and the renaming process can be
started by a click on the Start button.
