Pressing the Batch... button in the main tag window will open the Batch process window, shown below.

This dialogue allows you to carry out a number of operations as an automated batch process on all the files loaded. The actions you can carry out, either separately or all at once, are
- Use the filename to construct tag data.
- Carry out automated edit operations on either v1 or v2 tag.
- Insert an auto-incrementing track number. This setting is independent of any setting made in the main window.
- Copy frames from v1 to v2 or v2 to v1. Either all the frames, or a selection, may be copied
- Delete all images from the v2 tag
- Add a text frame or image to the v2 tag
- Write v1 tag.
- Write v2 tag, with or without trimming excess padding at the same time
- Rename the files. The renaming follows the rule as shown in the writable field if Advanced is selected. The rule can be selected from the popup menu button, or entered directly, and is independent of any setting made in the main window.
The actions are carried out in the order given above. When the files are being processed the Lock buttons in the main tag windows are obeyed.
The processing always starts with file 1 of the selection, whichever file is actually being displayed at the time. The batch processing can be done more than once on the same set of files if needed.
The final button Clear all locks when batch process ends, when ticked, will do just that. It prevents you being caught out by loading a new set of files when you have forgotten to manually clear the lock buttons.
Of the four action buttons at the foot of the dialogue, Close does just that without any processing occuring.
The Save button allows the current settings in the Batch process window (and the related Auto Edit and Copy Selection windows) to be saved, and they will be reloaded when ID3TagEd is next run. Reload enables these saved settings to be restored at any time after having changed (but not saved) them.
The Process button will start the batch processing.
