![]() The date is the first eight characters, the sequence number the last four digits, and the location sits in the middle. So a file renamed by myself looks something like this: 20160118-great_sandy_np-0001.CR2. I do a lot of outdoor photography so the custom text I enter happens to be the location of the shoot. What to enter is probably the biggest decision. If you really shoot more than this on a daily basis then make it a five-digit sequence. Combined with the date information above this gives 10 000 images per day (0001 to 9999). Including the time I regard as a rare edge case.Įnd with a four-digit sequence number. Almost all photographers do not need to include the time as well. Doing this will guarantee that that files will list chronologically. Start with the date in this format YYYYMMDD. In fact, a camera-generated filename is just a randomly-generated name consisting of digits and letters, and is neither meaningful, for a human, nor unique and so, duplication is possible. Some people get very excited about preserving the original, camera-generated filename, but unless there is some forensic auditing that is required then there really is not a good reason to preserve the camera-generated filename. If one is going to go to the trouble of renaming then at least make sure the result is meaningful to you. Meaningful names: A filename like 47qR45.JPEG may be unique, and prevent duplicates, but it is meaningless to a human being. If you have a renaming strategy that guarantees that each filename is, in fact, unique, then the situation outlined above just cannot occur. However, what happens if that file accidentally ends up in the same folder as the first MyDogSpot.JPEG? Hopefully both the OS and whatever application realise that they are actually two unique files but they may not - in which case unless you happen to have your wits about you, you may, in fact, allow one file to be overwritten by the other. Unique filenames - although a filename is more than just MyDogSpot.JPG, it actually includes the entire root, like this C:\My Pictures/2015/Birthday/MyDogSpot.JPEG, so having another image file of the same name but in a different folder means that the operating system and other applications will realise the two files are different. If, as Johan correctly suggests, that filenames are not the way to search for an image what is the point of renaming a file? I was so close to finding the solution.help me, Stephen Marsh-Kenobi.Johan is correct however, trying to decide exactly what is useful for a purpose is not necessarily that easy. ![]() I want to remove the number/letter sequences before the "DATE_TIME", resulting in the files being named: The sequence beings with a series of zeros and ends with a number and lowercase letter. Similar to a previous post, there is a sequence of numbers which changes. I too have a sequence of numbers and letters I want to remove from my filenames, of which there are hundreds. Due to a lack of knowledge in coding, I could not use the solutions you provided to solve my problem so am writing to you with the hopes you will catch this. Though I am chiming in here 1,127 days late and a dollar short, I am experiencing a problem similar to those of the previous posts. It is usually a wise move to tick the box “Preserve current filename in XMP metadata” so that it is easy to undo the batch rename if something goes wrong (also use the preview button on the upper right to preview all files, rather than just the single file preview at the foot of the interface). There are at least two valid approaches (notice the syntax highlighting to help understand what is going on): ![]() The following code does not care how many number of digits, just as long as the filename starts with 1 or more digits and ends in an _ underscore (offers greater flexibility than hard coding in a specific number of fixed digits). In the Find: text field type: _\d it should work on all 3 digit strings. From the second drop-down choose: Original Filename.
