You might not be aware but for ACR software to run on your computer it needs to meet a minimum spec (http://selfhelp.acr.com.au/workstation_specs.htm). There may be occasions when your computer’s hard disk can slowly fill up with data and once it reaches a critical point ACR will not launch and will display a warning message until the issue is resolved:
What can you do?
Resolving disk space issues can be a relatively simple process but as a word of warning, deleting any files or data from your computer can be dangerous. Only delete files that you know are no longer needed or have been backed up.
Disclaimer: ACR does not take responsibility if you accidentally delete important or critical files and recommend that you take a backup of any files or folders to a USB disk or other location BEFORE deleting any files. We also recommend that your local or onsite IT technician guide you with their preferred process if they are available.
Remove Old Files
Have a look at your Desktop, Downloads & Documents folders. There may be old files that you no longer need which you could simply delete.
Empty Your Recycle Bin
When you delete files in Windows, the default process is to “temporarily” move the files into the recycle bin without deleting them. This means the files are still using space on your computer and they manually need to be cleaned out from time to time. Look for the recycle bin icon on your desktop, right click it and select “Empty Recycle bin”.
Use Disk Cleanup
https://support.microsoft.com/en-us/help/17421/windows-free-up-drive-space
Windows includes a built-in tool that deletes temporary files and other unimportant data. To access it, right-click one of your hard drives in the Computer window and select Properties. (Alternatively you can just search for Disk Cleanup in the Start Menu.)
Select the types of files you want to delete and click OK. This includes temporary files,log files, files in your recycle bin, and other unimportant files.
Uninstall Desktop Programs you no longer need
Uninstalling programs will free up space, but some programs use very little space. From the Programs and Features control panel, you can click the Size column to see just how much space each program installed is using. The easiest way to get there is to search for “Uninstall Programs” in the Start Menu.
Analyse Hard Disk Space
To find out exactly what is using space on your hard drive, you can use a hard disk analysis program. These applications scan your hard drive and display exactly which files and folders are taking up the most space.
After scanning your system, WinDirStat shows you exactly which folders, file types, and files are using the most space. Ensure you don’t delete any important system files – only delete personal data files. If you see a program’s folder in the Program Files folder using a large amount of space, you can uninstall that program – WinDirStat can tell you just how much space a program is using, even if the Programs and Features Control Panel doesn’t.
Clean Temporary Files
Windows’ Disk Cleanup tool is useful, but it doesn’t delete temporary files used by other programs. For example, it won’t clear Firefox or Chrome browser caches, which can use gigabytes of hard disk space. (Your browser cache uses hard disk space to save you time when accessing websites in the future, but this is little comfort if you need the hard disk space now.)
For more aggressive temporary and junk file cleaning, try CCleaner. CCleaner cleans junk files from a variety of third-party programs and also cleans up Windows files that Disk Cleanup won’t touch.
