The Main Window’s Layout

Main Window Layout

The bar chart and the pie chart on the top show the non-removable area, and the area that can be reclaimed (Gray, White and Green).

The Graph

There are three different areas – Automatic Clean, Guard Privacy, and Advanced.

The files that SubRosaSoft Drive Cleaner can remove include the following:

Mail Downloads (Under Automatic Clean)

Mail Downloads Pane

Attachments to emails are stored here.

They are additionally stores in the email message itself, so deleting them will make no difference apart from freeing up some space.

Logs (Under Automatic Clean)

Logs Pane

Logs are kept by applications in order to create a history that may be of use for diagnostics.

or example a log is generated every time an app crashes in case the developer needs to determine what happened. Over time these can build up.

Cache (Under Automatic Clean)

Cache Pane

Caches speed up applications by duplicating commonly used data so it can be accessed again faster in the future.

However caches sometimes become bloated, and this can result in both slower application performance and wasted disk space.

Guard Privacy (not available in demo mode)

Guard Privacy Pane

For quarantine purposes a log of all files that have been downloaded is kept permanently.

Over time that list is no longer needed. If you would rather it were not present on your computer you can delete it here. Deleting it will remove only the list, not the files themselves, so it is safe to do.

Sleep Image (Under Advanced)

Sleep Image Pane

Remove the file /private/var/vm/sleepimage

This file is the contents of memory written to disk the last time of your computer hibernated, in order to read it back into memory when it wakes up.

You can safely delete this file any time your computer is awake. It is necessary to do this manually because Administrator rights are needed.

To delete the Sleep Image, click Delete Sleep Image. The action should happen in seconds and easily will reclaim one or more gigabytes.

Application Support (Under Advanced)

Application Support Pane

The Application Support folder (~/Library/Application Support/) contains essential items for applications. However if you have deleted an application and will not be using it again, there are often remnants left over that can very large.

It is worth taking a look for anything left behind that you’re sure you don’t want. You can pick what to delete based on your needs.

Removing Application Support files requires you to manually determine what to delete. Click the magnifying glass button at the bottom of the Application Support panel; Drive Cleaner will display a list from which you can manually select and delete.

Application Support Window

Quick Tip: What to remove
Applications you installed and no longer need are good candidates for removals.

Foreign Language Files (Under Advanced)

Foreign Language Files Pane

In general, applications contain all of the data related to the application in every language that the application supports.

To free up space being used by language files you will never use, click this button. Drive Cleaner will scan through the .app bundles and delete them automatically.

Scanning for Foreign Language files may take more than a few minutes as there are many files to scan thru.
