In addition, Delenda allows to display continuously the number of files in each defined folder or tree. Purge the contents of a defined set of folders. Can remove the contents of sub-folders. Can use the file modification date or the file creation date

"There is an option to delete all files of a folder if and only if all the files are obsolete (i.e. no files are deleted if there exists a file of the folder which is not obsolete) Set the daily hour of the purge Set the 'keep time' for each folder; for example, you can erase files older than 24 hours in a folder, older than 48 hours in a second folder, etc. It can also be used as a Windows NT or 2000 service and in command line mode."
