Furthermore, in this tutorial, we will explain the way to create a batch to delete file automatically using the command line. This is useful if you have limited space on an HDD and need to delete files on some folders that populated automatically.
In my case SQL backups folder. After the tutorial where we created batch to zip files , this is another useful tutorial for your daily jobs. You will need to delete those files manually every day and this is not good practice.
On the other hand, you can create a script to delete the file automatically. All of that without installing any third-party software.
In fact, this example will show steps for creating a batch file and you can use Task Scheduler to run. In fact, Batch files are scripts that can run to perform tasks on your system. They are the best ways to save time. In fact, we will delete files on specific folders. NOTE: The code above takes into account leap years, as well as the exact number of days in each month. NOTE: The math only goes one way; it cannot correctly get future dates from negative input it will try, but will likely go past the last day of the month.
Originally suggested my Iman. It cleans anything older than 15 days out of my 'Temp' folder and 30 days for anything in my AutoCAD backup folder. I use variables because the line can get quite long and I can reuse them for other locations. You just need to find the dos path to your recycle bin associated with your login. This is on a work computer for me and it works. You might be able to pull this off. You can take a look at this question , for a simpler example.
The complexity comes, when you start comparing the dates. It may be easy to tell if the date is greater or not, but there are many situations to consider if you need to actually get the difference between two dates. Expanding on aku's answer, I see a lot of people asking about UNC paths.
Simply mapping the unc path to a drive letter will make forfiles happy. Mapping and unmapping of drives can be done programmatically in a batch file, for example. This will delete all files with a. If you want to make sure Z: isn't mapped to anything else before using it you could do something simple as. This one did it for me. It works with a date and you can substract the wanted amount in years to go back in time:. The script will allow you to use measurements like days, minutes ,seconds or hours.
To choose weather to filter the files by time of creation, access or modification To list files before or after a certain date or between two dates To choose if to show files or dirs or both To be recursive or not.

FILE is only the name, so if you're dealing with subfolders, it won't work.
This answer works when "older than 7 days" is defined as "modified more than 7 days ago" rather than "created more than 7 days ago". How can the latter be achieved? Show 22 more comments. David Tonhofer Iman Iman 6 6 silver badges 2 2 bronze badges.
For the most part, this is a fairly impractical answer. If I have a directory with lots of data in it, there is will not work well.
I'd go with one of the answer that does it "in place" — adamb0mb. As robocopy is really robust, it will in fact work for any directory size, obscure file names, basically arbitrary path lengths and include directories if you need it to - something which surely cannot be said about many other Windows utilities.
Plus, robocopy does support UNC paths - which forfiles from the accepted answer won't do. My thoughts were more along the lines: "My files are already where I want them. I don't want to have to move them. Don't overload Robocopy to do it" — adamb0mb. Show 2 more comments.

First, the tables: Days since UTC for each year including leap days. Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Year with days: 0 31 59 90 Year with days: 0 31 60 91 Converting a date to number of seconds since is quite easy using those tables. Attention please! The file can be deleted if seconds rem value is lower than the value calculated above. Further the batch code below is optimized for 24 hours time format.
