How to delete files from a recursively expression-based folder?

I’m using a project where there are several temporary files that, for some reason, have not been deleted over time and that are taking up a lot of space.

I need to delete all images from this particular directory recursively when these files start with the letters "LX".

How can I do this using Powershell or CMD?

For example, in the structure below, each of the subfolders has these files initiated by "LX".

DIRETORIO
    FOTOS_1
       1.jpg
       2.jpg
       LXa45axdgg.jpg
    FOTOS_2
       1.jpg
       2.jpg
       LXa4bbbbxdgg.jpg
    FOTOS_3
       1.jpg
       2.jpg
       LXa4555g.jpg

Using the cmd, you can do the following:

del /s *.{sua extensão}

or if you wish by file name, you can do the following:

del /s LX*

Remembering that for this you must be in the "root directory", ie in DIRECTORY.

If you want a confirmation before deleting each file, use the option /p.

Using the Powershell is easy.

get-childitem . -include LX*.* -recurse | foreach ($_) {remove-item $_.fullname}

The command Get-Children returns a collection of files.

  • The point (.) represents the place of departure (the folder where the script is spinning).

  • The -include LX*.*, serves to "tell" the command to return only files that satisfy this condition.
    You can add more conditions by separating them by comma: -include LX*.*, lx*.*.

  • The recurse makes the command recursive. That is, look inside the daughter folders of the current folder and inside the daughters of the daughters and so on.

After Get-Children is made a foreach which passes through all the elements of the collection and calls the command remove-item to delete it.

Del/f/s/q LX*.*

/f = Strength Read Only File Deletion

/s = includes ALL subdirectories, ie will delete ALL the files initiated in LX of all directories from which you execute the command.

/q = does not ask for confirmation. If you wish to confirm, one by one, use /p.

Remember that using the /s, the command will delete from ALL the folders then make sure that you can actually delete ALL these files.
