  • Compression of old files
  • Temporary Internet files
  • Temporary Windows file
  • Downloaded Program files
  • Recycle Bin
  • Removal of unused applications of optional Windows components

The above list, however, is not exhaustive. For instance, ‘Temporary Remote Desktop files’ and ‘Temporary Sync files’ may appear only under cretain computer configurations, fifference such as Windows Operating System and use of additional programs such as Remote Desktop. The option of removal hibernation data may not be ideal for some users as this may remove the hibernate option.

Aside from removing unnecessary files, users also have the option of compressing files that have not been accessed over a set period of time. This option provides a systematic compression scheme. Infrequently accessed files are compressed to free up disk space while leaving the frequently used files uncompressed for faster read/write access time. If after file compression. A user wishes to access a compressed file, the access times may be increased and vary from system to system. In addition to the categories that appear on the Disk Cleanup tab, the More Options tab offers additional options for freeing up hard drive space through removal of optional Windows components, installed program, and all but the most recent System Restore point or Shadow Copy data in some versions of Microsoft Windows.

Disk Defragmenter window: The Disk Defragmenter window consists of two main areas. The upper portion Lists the volumes on the local computer. The lower portion displays a graphical representation of the amount of fragmentation on the volume in colored horizontal displays called Estimated disk usage before defragmentation and Estimated disk usage after defragmentation.

Each bar under bar under Estimated disk usage before defragmentation and Estimated disk usage after defragmentation represents a grouping of dozens or even hundreds of clusters, depending on the size of the volume and the cluster. The displays are not large enough to depict each disk cluster in a volume as a vertical colored bar.

Disk defragmenter does not attempt to consolidate all of the free space on a volume. Although free space fragmented into hundreds of pieces space consolidated in a single location provides very little performance benefit. Because fragmented files, contiguous files, files that cannot be relocated from their current positions on the disk (unmovable files), and free space can all reside in the same group of clusters, the color of each vertical bar is determined by the following rules:
