We can recall these matches with the new format, for example if we set the new format toĬhanging the 'old format' or 'new format' will generate new 'new filenames'. They are essentially a * wildcard (lazily match any character any number of times)įor example, take the following filename:Īnd storing what * matches in the variables called %1 and %2 %1, %2, %3 have special meaning, these variables capture matched text in the old filenames. These two fields are automatically generated, based on the initial filenames.ĭepending on the initial filenames, there might not be any noticeable patterns, in which case Everything will use %1 for the old format and new format (%1 on its own will match the entire filename).

Old format and new format define the old filename pattern and new filename pattern. What is a more detailed explanation for using the 'Old Name' and 'New Name' text boxes? Sorry for being rather uneducated, I have little more than high school basic knowledge. How does explicitly clicking the 'Match Case' and 'Regex' boxes help my task? Or do I always need too leave them unchecked? How do I apply the additional tools to the job by clicking the 'right arrow button(s)' which reveals a whole new set of functions? What do the those new functions mean ?

What is a more detailed explanation for using the 'Old Name' and 'New Name' text boxes? When you have a list of file names these boxes now show something in them that is rather a vague representation of what seems to be MSDOS commands. I have before, used the 'rename' command for this task, but because I do not fully understand the 'language', it seems that I lack knowledge, of how to do these sorts of tasks more efficiently than just selecting each and every file, one-by-one to rename.

Is there a walk thru for file renaming? I have a bunch of irregular named files, that I would like to rename them, into a much more organized format.
