Batch file rename — a wonderful drug that everyone wishes to have when you have to rename multiple files at a time. I guess a lot of us have faced with monotonous, tedious, but necessary work as renaming of photos and there is no wonder that to ease this work a lot of batch rename files Mac solutions, as well as solutions for other operating systems, appear on the market. So how to rename a file on Mac with absolutely no effort and within a couple of minutes?

From this article, you will learn how to rename files in bulk as well as some of the reasons for batch renaming. As we all know, sometimes there are situations when you need to rename a large number of photos, as you may get them from various sources. For example, when using different digital cameras, the names of the photos have different attributes and are unattractive, something like DSC01479.JPG.

They are difficult to pronounce, and even more, they do not carry any useful information. After a certain amount of time passes by and the number of photos became more and more, it could be difficult to find the file that is of a great interest to you. However, if you use batch image rename tool, you can simplify the later search for the files and make the files more informative. For example, instead of names like DSC01.JPG ... DSC999999.JPG there will be a group of files with names, for example, Christmas01 ... Christmas999999.

Rename multiple files

Perhaps, you have ever wondered how many years your child was on that or other photos or in which year exactly did you have such a wonderful New Year tree with such fluffy branches? When you shoot a photo, it seems to you that this moment will be remembered forever. But alas! Unfortunately, we can forget not only the exact date but also the year of the taken picture too soon. Of course, the date and time of creation are always kept in the information about the file, but when you have to sort multiple pictures into different folders, the process of finding out the date this way requires a lot of time, that unfortunately, not a lot of us have. Would not it be more convenient to indicate the date in the name of a file? Thus, you will never need to check whether the actual date of the photo was changed when copying files to the computer or any other operations.

What is meant under the term batch file rename?


Under the term batch renaming of files (photos), it is meant the replacement of the original name of the file by the desired one based on some principle. The process of batch renaming is usually done automatically. As a rule, the new name is usually consists of a common name (part) and an individual item (part) for every image in bulk. For instance, Sea001, Sea002, Sea003, etc. As you can see from this example, the common part is SEA and the individual part is the file sequence number.

Why is it necessary to make batch file rename


  • For instance, when you were on a long holiday abroad and upon the arrival home you have gathered all the photos from people you have been with as well as from all your devices. So when you have done this, you can see a lot of files with absolutely no meaning. It is no wonder that you want to make an order with the files instead of having a lot of folders with some sort of letters and numbers. As we have said earlier, the names that are assigned to the camera images when shooting are totally uninformative. That is why it is completely impossible to guess which picture is hidden, for example, under the name DSC02799.jpg. Therefore, when copying photos from a camera to a photo archive on a hard disk or somewhere else, they are usually renamed, giving descriptive names, telling about when and where the photo was taken, what event is displayed on it, and so on and so forth. It is useful, for example, to specify the date (possibly only year and month) in the name of the photo or the number of the frame, for example, 2011-09-05_0015.jpg or 2011-09_0015.jpg where 15 is the number of the frame, shot on September 5, 2011 or in September 2011). It is also possible to add the name of a place or an event to the name of the photo. The variant of the name of a particular photo from the group, in this case, can look something like Trolltunga_2011-09_0015.jpg.

  • The unique names of your photos can help you to identify your images, as they allow you to differ every single photo from each other. In case, if you are not using unique names sooner or later you will face the issue that the names of the photos would be duplicated when moving images from one folder to another or from one drive to another. For instance, you had the photos take on the 4th of July. Your camera creates the names for the files DSC01479.jpg, DSC01480.jpg, DSC01481.jpg, DSC01482.jpg. The same day you move the taken photos to your hard drive and erase the card of the camera and go for another shooting. Once again, your camera creates the names for the files according to the same structure DSC01479.jpg, DSC01480.jpg, DSC01481.jpg, DSC01482.jpg. I think there is no need to explain what will happen when you try to copy these photos to your hard drive….two files with the same name, but with different content. You can imagine all the mess.

  • One more variant when renaming can be rather handy is if you are a photographer. As we all know photographers edit photos a lot and even one photo can be edit thousands time. So adding sequential number can be of a great help here, as with its help it is easier to track the versions of images and to keep the history of editing.

  • Renaming in bulk is also considered to be the second important process when creating a proper digital archive. This can help in searching your files within a couple of clicks and minutes. Generally, in order to rename photo Mac users specify the file name mask in a general view. Usually, English alphabet letters, numbers, underline character, the year and month of the shooting, the serial number, and other characters can be used in such a mask (please note that symbols in different utilities may differ).
