First, add the files to the list, whose file name you want to shorten. For that, add the parent folder(s)
of the problem-causing files via drag & drop onto the program interface. As type to read in set
Files and Include Subfolders.
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.
Rename Expert allows to filter files for selectively editing only those files that contain too many
characters in the file name. Set, as shown in the figure, the number of maximum allowable characters
in the path or file name, and the program displays only the files matching the filter criteria in the list.
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.
