Clears unnecessary files from your computer's hard disk. You can use command-line options to specify that Cleanmgr cleans up Temp files, Internet files, downloaded files, and Recycle Bin files. You can then schedule the task to run at a specific time by using the Scheduled Tasks tool.
Downloaded Program Files Folder
Downloaded Program Files - Downloaded program files are ActiveX controls and Java programs that are downloaded automatically from the Internet when you view certain pages. These files are temporarily stored in the Downloaded Program Files folder on the hard disk. This option includes a View Files button so that you can see the files before Disk Cleanup removes them. The button opens the C:\Winnt\Downloaded Program Files folder.
Temporary Files - Programs sometimes store temporary information in a Temp folder. Before a program quits, the program usually deletes this information. You can safely delete temporary files that have not been modified within the last week.
Temporary Offline Files - Temporary offline files are local copies of recently used network files. These files are automatically cached so that you can use them after you disconnect from the network. A View Files button opens the Offline Files folder.
Offline Files - Offline files are local copies of network files that you specifically want to have available offline so that you can use them after you disconnect from the network. A View Files button opens the Offline Files folder.
But when I checked the contents of that folder from a command line, usingthe dir command, I didn't see anything indicating there wasany Java-related files in the directory. Instead, I saw the following:
But I can run a Visual BasicScript (VBS) script from the command line to obtain information similarto what is available from within Windows Explorer.When I ran the script show-downloaded-program-files.vbs, I saw thefollowing:

Windows contains plenty of files and folders that you don't really need. Between hidden caches, old junk that wastes space, and files you can actually delete to solve problems, knowing what's safe to remove from Windows can be challenging.
Let's step through some Windows files and folders that are totally safe to remove, along with why you might want to erase them. This will help you free up disk space and learn more about your PC. Note that some of these folders are in system-protected locations, so take care when deleting them.
Aside from wasting time doing this yourself when you could automate the process, it's safer to let the Disk Cleanup tool do these cleanings for you. This avoids accidentally deleting files that you need or messing with the wrong folders.
Whenever you upgrade your version of Windows, the system keeps a copy of your prior files, called Windows.old. This folder essentially holds everything that made up your old installation, in case something didn't transfer correctly.
Obviously, removing these files makes it harder to recover data in case of an issue. After performing a Windows upgrade (even just to the latest version of Windows 10 or 11) we advise you to hold onto this folder until you're sure everything is working properly.
This folder's name is a bit confusing; it doesn't have anything to do with apps you've downloaded. Instead, it holds files used by Internet Explorer's ActiveX controls and Java applets, so if you use the same feature on a website, you don't have to download it twice.
The LiveKernelReports folder is another directory that likely comes up when you're scanning for large files on your computer. This folder is home to dump files, which are ongoing information logs that Windows keeps. If your computer runs into an issue, you can analyze the contents of these files to start troubleshooting your problem.
Any huge files ending with the DMP file extension in this folder are safe to delete if you don't need to look deeper into them. Like the above locations, though, we recommend using Disk Cleanup instead of deleting the file yourself.
While the Rempl folder isn't large, you might be surprised when you see it appear on your system. It contains several small files, and you might even notice a few Task Manager processes connected to it.
It takes a bit of looking around to find them, but Windows holds plenty of files and folders that aren't necessary. Remember that your computer does a pretty good job of keeping itself clean, so you don't have to constantly remove the contents of these folders unless you're really low on disk space.
Downloaded Program Files are Activex controls and Java applets downloaded automatically from the Internet when you view certain pages. They are temporarily stored in the Downloaded ProgramFiles folder on your hard disk. Feel free to delete them.
Step 2. After the process, select the "Deleted Files" and "Other Lost Files" folders in the left panel. Then, you can apply the "Filter" feature or click the "Search files or folders" button to find the deleted files.
/bin and /usr/bin is where the scripts are that start the programs. The direct equivalent of "Program Files" though is probably /opt or maybe/usr/share (see Filesystem Hierarchy Standard). That directory contains the various support files for most programs.
To find out where a specific program is installed, you can do a number of steps. First you need to locate its .desktop file. Desktop files are simular to shortcuts in Windows, and for system applications they are located in /usr/share/applications. The desktop files for applications that are only available for the current user are in /.local/share/applications. Take for example Google Chrome, which has the desktop file /usr/share/applications/google-chrome.desktop and look for the line that starts with Exec=, this determines how to start Google Chrome. It says:
In windows, every program that we install gets its own directory inside the Program Files directory. In that directory, further sub-directories are created for different kind of files. There is no fixed structure for sub-directories. Programs decide for themselves what they want to call each directory and where they want to put what.
But in Linux when a program is installed, different kind of files are copied to different locations. Executables are copied to /usr/bin, library files to /usr/lib, documentation to one or more of /usr/man, /usr/info and /usr/doc. If there are configuration files, they are usually in the user's home directory or in /etc.
Ubuntu doesn't really have a programs folder containing all of the data for each program. In Unix and Unix-like operating systems, EVERYTHING is a file, even the terminal commands. They're files as well. The way Unix handles programs can be pretty chaotic, and organized at the same time.
In Linux, your files are split up between specific sub directories depending on their function. There are directories for libraries, icons, man pages, Log files, configuration and so on. You may use some of them, but the system will manage all of them. They are not coupled together, but exist together with similar files from other programs.
If you normally use the Disk Cleanup tool in Windows 10 to remove temporary and unnecessary files, after installing the Windows 10 October 2018 Update you need to be more careful. This is because Microsoft has quietly added the "Downloads" folder as an additional location that files can be removed.
After updating to the October 2018 update, users are now performing the same process and not realizing they are also selecting the new "Downloads" option as well. This causes all of the files that have been stored over the years to be deleted from the Downloads folder and users are not too happy about this.
It's important to understand that the "Downloads" option is unchecked by default and it's a helpful feature to those that use downloads folder for temporary files. On the other hand, if you use it as a place to store needed files, make sure the option is unchecked or you will lose the content stored in the folder.
A few months ago I changed the download settings on my computer (Windows 10) so that whenever I download a file from the web, it prompts me to choose where I want to save it (e.g. Downloads, My Documents, Desktop, etc). Before changing the settings my computer would automatically save most program files to the Program Files folder (naturally). But today I was trying to download the Anaconda/Python software, and I figured I should save it to the Program Files folder. However, when I choose this folder at the download prompt it says "You don't have permission to save in this location. Contact the administrator to obtain permission." But this is on my laptop, and I am the sole user. So how don't I have permission/how can I obtain permission? 2ff7e9595c
