With the File Renamer mode you can quickly rename a bunch of files.
Enter a folder in the "Folder"-entry or click on the "..." button to
browse for a folder.
You can enter a certain file filter to select only those files you're
interested in. For example "*.txt" or "*test*" (without the quotes!).
Select the files you wish to rename in the file listview.
Enter your format for the filenames.
To insert a basic numbering somewhere in the file use "%i".
Use something like "%.4i" to insert numbers like "0001". The 4 is the
amount of digits you want.
(For advanced users: the syntax is equal to the syntax of printf().
Only type "i" is supported.).
You can click the "Add Num..." button to get a list of numbering
formats. Click on one to insert it in the "Filename format" on the
current cursor position.
Enter your starting index. The file numbering will start with
this number and will be automatically incremented with the given
increment after each file.
Specify the increment for the file numbering.
If you want to preserve the extension of the files, enable the
"Do not change extension" checkbox.
You can use the "Auto Fill Values" button to automatically fill
in the "Filename format" and the "Starting index" based on the selected
file. This will not always give the right results, so it is
recommended that you check the values before you continue.
