I'm not sure that I've seen any outside of empty text files before I edit them. It seems that all sorts of programs create (and, if they're nice, maybe eventually delete) these files. I would NOT delete 0-byters on the system drive, ever. Only delete them in data directories where you know what you're deleting. Or just ignore this script entirely -- it's kind of an idle curiosity. But if you're curious and just want to list the files without deleting anything, do DelZero C:\ /R /N /Q.Â
CarlD Posted February 6, 2021 Author Posted February 6, 2021 (edited) Turned this around so that, by default, it only lists 0-byters, does not delete them. Use the new option /D to delete the listed files. Compare: ListZero C:\ /R /Q  with: ListZero C:\ /R /Q /D <== NOT RECOMMENDED Edited February 6, 2021 by CarlD Update
Exit Posted February 6, 2021 Posted February 6, 2021 @CarlD Unfortunately, your script does not consider alternate data streams (ADS). Here's the proof: Open the command prompt and enter the following commands: 1.) echo This is a file with valid data>test.txt:valid_data 2.) dir / R test.txt Test.txt is listed as empty file in your script, but it contains 32 bytes. The proof is: 3.) notepad test.txt:valid_data Musashi and CarlD 2 App: Au3toCmd       UDF: _SingleScript()                Â

Will have to investigate as I've played with ADS exactly once in the past. Thank you for pointing this out. In the meantime, I changed around some options, and added an option /X exclude_file, where you can list the extensions of files that you want to exclude from the listing. Â
CarlD Posted February 7, 2021 Author Posted February 7, 2021 Added check for alternate data streams (ADS). Can be disabled with option /-A. Exit 1
Exit Posted February 7, 2021 Posted February 7, 2021 @CarlD Perfect solution. Here is a small suggestion for improvement: Possibility to use the recycle bin 🚮 The option could be: /DR (delete to recycle bin) CarlD 1 App: Au3toCmd       UDF: _SingleScript()                Â

CarlD Posted February 7, 2021 Author Posted February 7, 2021 Added the /DR option -- thanks! The usage has changed slightly. You must specify at least one path on the command line. ListZero with no arg shows help. Exit 1
