Hi and thank you for your answer. Atime and Mtime are Access Time and Modification Time as native properties of files and folders in most filesystems (sorry atime and mtime as names are maybe mostly linux stuff). You can easily see these properties setting a custom directory view (using Details listing) in File Explorer, and choosing to show them as custom columns when listing the directory. If you check Variable Set From File, there is the option to check and set variables according to the file time properties, one for Access Time and one for Modification Time. But I am not sure if I can do the same check with folders. The check floders this way is very handy monitoring or scanning a filesystem for changes, for example for backup, archive or versioning macro. When a file is changed within a directory, also the mtime and atime of its directory is changed. This means that if you are scanning a filesystem with 1.000.000 in 100.000 folders to perform any action on the files, you can skip all the folders that have a mtime later than a preconfigured date, making the script by far faster. I hope I was able to explain myself a bit better. Cheers
