Rename Files
Top  Previous  Next

Rename Files* is an easy to use tools. Allows to mass rename several files at once.

When you enter to this option, you'll get a "
Select files" dialog to select one or multiple files to rename (if you don't like this behavior, just disable the "Ask Files on Start" option in Settings tab).

You may drag and drop files from Windows Explorer (or compatible program) to Rename Files window. All dropped files are added to list, if a subfolder is included and "Recurse Subfolders" option is checked, all subfolders contents are added too.

lightsmallRename files shows a checkbox next to each file. Only checked files will be processed. This mechanism is to avoid accidents or errors when you processing files. When you rename files, is a good idea to keep then not longer than 64 characters. All tabs uses the rename rules specified in Common Rules. Please remember two concepts: filename part and extension. The filename part is the complete name of a file without the extension. The extension is usually the last 3 characters followed by a period. Example: file.txt --> filename part is "file", extension is ".txt".
lightsmall By default, Rename Files shows an Automatic Preview of how your files will be renamed using the parameters you specify. The file list shows the original file name, and the Preview of New Name. All files that change the name based on your parameters, will show an arrow right. You may see a warning symbol warning if some name may be unable to use in Windows.

Counter
The Counter tab is to rename files using counters.

For example: you start with number 1, you have 150 files in list and you set digits to 2; when counter reach 99, it can't be 100 because is beyond limit of digits, so is reset to 0. If the counter mode is Descending, the counter is reset to the greatest number supported by specified digits (if digits = 3, counter is reset to 999 if needed).  
·Separate with: you may enter a text to separate the counter from the filename (if Insert Counter is enabled). The default is one space. You can select a previous used text while you type, or use the arrow to get a list.
