Where is my Disk Space? was inspired by my brother whose hard disk was full up and he did not know where all the space had gone to. I had to trawl through all his folders finding out where all the space had gone. Using Sherlock found large files quite easily but was very slow. But it could not find folders that were using a lot of disk space, duplicate files, empty folder, or files which were part of a useless folder that could be trashed.
1. Select a disk to analyse.
2. Wait while Where is my Disk Space? loads in the file data. A status bar with time remaining will show how long there is left until it is finished. This can take several minutes for large disks with large numbers of files.
3. After the disk has been analysed a window will appear showing the top 500 largest files on the disk with the largest at the top.
4. Double-clicking on a file will reveal it in the Finder. This feature is not available in demo mode.
5. You may then move the file to the trash if it is no longer needed.
6. You can ignore certain files by type or by being in the same folder as another file. Just select the file and choose Ignore this type of file or Ignore other file in this file's folder from the Options menu. This feature is not available in demo mode.
7. At any time you can clear this by selecting Show all file types.
8. You can save the window as a tab delimited text file using Save from the File menu. This feature is not available in demo mode.
Other Options Menu items
Use import to add another disk into the main window. This is useful for finding duplicate files across multiple disks.
Find files of this type
When you have a file selected you can find all the other files of the same type and display them in size order in a new window by selecting this command. This may be useful in quickly finding all the applications on your hard disk by selecting any application and choosing this command. This is the same as double clicking on a file type in either the 'Which type of files do I have most of?' window or the 'Which type of files use most disk space?' window.
Which type of files do I have most of?
This window shows the top 500 file types and how many files there are of each type. Although this is not that useful it does give an indication as to what you have used most of your disk space on.
Which type of files use most disk space?
This window shows the top 500 file types and how much disk space each file type uses. Although this is not that useful it does give an indication as to which file types are using most disk space.
Which folder has the most files in it?
This window shows the top 500 folders by how many items there are in that folder. A folder with a lot of files in may need looking at as many of the files may be useless.
Which folder uses the most disk space?
This window shows the top 500 folders by how much disk space they use. Unlike the Finder it does not include the size of folders within the folder. A folder which uses a lot of disk space may not show up using traditional methods as it may be full of very small files.
Find Duplicate Files.
This window will scan all the files and if they have the same type and same name and have the same sized data and resource forks then it will read the first 100K of both forks of the files and see if they are the same. If they are the same it is assumed that the rest will be the same for speeds sake. You can also select this command in a window showing only one particular type of file using the 'Find files of this type' command. This will be very quick as it only has to scan a few files. This feature is not available in demo mode.
Find Empty Folders.
Although empty folders do not use up disk space (not much anyway) you can find where you have entra garbage on your hard disk. In Mac OS X there are a lot of empty folders and most of them need to remain. This feature only tells you how many empty folders there are in demo mode.
Find Bad Aliases.
Aliases also do not take up much disk space but it is no use having aliases that no longer point to any file or folder. However some aliases that are marked as bad may just be because the server that the file that the alias is pointing to is on is not mounted. You can double click on these aliases and see if the alias resolves in the Finder once the server is mounted.
