DirSize

DirSize is a command line tool to show you how much disk space is used and wasted in each directory. You will find that it is far faster and more accurate than other similar tools, completing scans of 1.2 Terabyte disk structures in 40 minutes while other apps take 2 hours and are still not complete.

Its uses include:
• Finding space hogs on a network
• Finding multiple copies of a single application on a server
• Finding which directories could be archived to save space (typically those that contain lots of small files)
• Finding where most of the disk space is used
• Finding applications to remove before installing a new one
• Previewing the benefits of a smaller cluster size
• Generating daily, weekly or monthly reports showing how the disk space distribution has changed. You can easily generate html, tab- or comma-delimited output to feed directly into your favorite spreadsheet for further analysis
• Showing you the complete directory tree
• See sample HTML report

On large hard disks up to 1/4 of the total drive space is wasted! DirSize will show you where.

DirSize includes both a 32-bit version and a 16-bit version for backward compatibility. The 32-bit version of DirSize runs under Microsoft® Windows® 8 and x64, Windows 7 and x64, Vista®, Vista 64, 2008/2003 Server, XP. The 16 bit version of DirSize runs under DOS, Windows 3.x, 95, 98, ME, NT, 2000 and XP, but does not show long filenames.

User Benefits

• DirSize can now ignore the sizes of offline files.
• The directory tree can be limited to just those branches showing more than a specified amount e.g. 20 MB. This is very useful to find out who is hogging space on a network.
• Displays Windows 95 long filenames.
• Uses international thousands separator based on country information.
• For the drive, displays cluster size, free space, used space and capacity.
• For each directory shown, displays total space used, wasted space (either as a percentage or as an actual value) and directory name. If the directory has sub-directories, it also shows the combined total -this is very useful for finding the complete size of applications before deletion or backup.
• For the files examined, displays total used space, total wasted space and the cluster size used (the user can specify a size other than the drives actual cluster size so that they can see how much space would be wasted under a different configuration).
• Rounds up file sizes to the cluster size AND includes the size of each directory for the most accurate size information.
• Fully scrollable output (both up and down).
• Comma-delimited and tab-delimited output formats for easy importing into databases, spreadsheets or word processors.
• Future proof - directory sizes up to 99 GB are catered for.
• Output can be redirected to a file or to the printer.
• The characters used to draw the directory tree can be changed from DOS extended ASCII characters to standard ASCII characters.
• The statistics can be disabled to show just a directory tree.
• Directory sorting can be disabled. This is useful for comparing DirSize's output with an unsorted DIR output.
• Continuous progress indicator while accumulating file information.
