Find file type and delete all but largest one

Posted Fri, 25 Jun 2021 05:27:51 GMT by

I have a folder with around 3k files in it that i need to go through and get the largest of each file type and only keep that one. is there a way to find the largest of a specific file type extension and then delete the remaining of said types. folder set up is like below:

(filename1).file1_abc	50kb
(filename2).file1_def	50kb
(filename3).file1_ghi	230kb
(filenanme1).file2_abc	50kb
(filename2).file2_def	187kb
(filename3).file2_ghi	50kb

... and so on for about 50 separated file types. the only ones id like to keep in the example would be (filename3).file1_ghi and (filename2).file2_def

is this possible to do? thank you for any help!

Bradley,

Looking for the largest file in the folder would be pretty easy. You can get a dataset with all the files then

loop that dataset and build another dataset that contains a list of all the extensions

the loop that new dataset and get a list of files with only that extension. Loop that list and find the largest file

and then do that for every extension. Please let us know if this makes sense.

Thanks, Chris
