When you search for a file in Windows 10, how do you specify a wildcard for any number?

To give you an example: I know that a file is called something like: some-picture-100x100.jpg.

I do not really know the resolution. It could also be some-picture-360x360.jpg, but it definitely has 3 numbers on the left side of an x and another 3 numbers on the right side of it. How do I search for that?

Edit: If you know RegEx, what I'm looking for is the equivalent to [0-9]. It seems not to exist, but if it does, please let me know.

    AFAIK the only two wildcards are * and ? While not perfect you could search "* ???x???.jpg"

I don't believe there's a specific wildcard for a "number" rather than a character, but you can make use of the DOS-type wildcards * and ?.

* would match 0 or more characters, while ? would match a single character.

You can also use the filename: flag to indicate you only want to search filenames.

For example, you could try this in the Windows Explorer search box: filename:*-???x???.jpg

  • Thank you. I thought there might be something equivalent to [0-9] in RegEx. Since I want to delete a lot of files that match this pattern, I have to be careful then not to delete anything that has letters instead of numbers at these positions. Feb 23, 2018 at 17:18
