Rename png file in bulk

[nursyfnz]

Hi, I need help to programmatically rename png file in bulk with numbering 1,2,3, and so on using LabView. I only want to use number for the name of the pictures.

Are they all in one folder or in an entire hierarchy?

You can use "list folder" or "recursive file list" with *.png as pattern, then process the files in a loop and moving the old name to the generated new name for each. Is there anything you need more detailed help?

Make sure you use the proper path tools and don't operate on full paths as strings. Only the filename operations should involve anything "pink".

How should the numbers be assigned? Based on alphabetical order? Based on creation date? Randomly?

If you turn names into numbers, I would also make sure to use a fixed number of decimal digits padded with zeroes (e.g. 001, 002, 002 ... 099 ... 234 ...) so alphabetical and numerical ordering is the same.

You can use the "Move" function to rename files (Functions → Programming → File I/O → Adv File Funcs → Move)

All  images are in one folder. I want it to be arranged based on time. The first one would be named as 1, next will be 2, and so on. I don't want any other character as shown below.

Are the current names such that if they are sorted by name they are also sorted by date or do we explicitly need to sort by the timestamp?

Would it be sufficient to create a new name that corresponds to the number inside the parentheses of the existing name? As I already said, you need to be careful with the sorting, because e.g. "12" would come alphabetically before "8".

They are sorted by name they are also sorted by date. No, It is not sufficient to create a new name that corresponds to the number inside the parentheses of the existing name. You may ignore the number inside the parentheses as it is not sufficient. Just numbering 1,2,3... are needed.

See if this can give you some idea.... (make a copy of the folder before testing, just to make sure....)

For robustness, you might want to sort on the date:

I agree with Paul that you still might want to sort by date, because windows explored does some mixed sorting that might not be fully alphabetical if the name also contains numbers.

The file list on the LabVIEW function will be fully alphabetical and might not agree with what you see in windows explorer.
