DIRSIZE v2.6 ============ Copyright 1993-1996 Simon A Carter The Directory Size/Wastage Lister with the Lot: * Summary statistics for multi-level directories. This is very useful for finding the complete size of applications before deletion or backup. * Displays Windows 95 long filenames. * For the selected drive, displays actual cluster size, free space, used space and capacity. * For the directory tree, displays cluster size (user-selectable), total space used and wastage (as a percentage or as a value). * For each directory displayed, shows total space, wasted space (as a percentage or a value), and if it has subdirectories, the total space used by the directory and all of its subdirectories. * Shows wasted space for a given cluster size - optimise your cluster size before repartitioning your hard disk. * Rounds up file sizes to the cluster size for the most accurate size information. * Size/wastage information includes the size of directories themselves. * Paginates output, [Enter] for next line, [Esc] to exit and any other key for next page. Disabled automatically if output is redirected. * Output can be redirected to a file or to the printer or into another program. Redirection is automatically detected and turns off pagination. * The characters used to draw the directory tree can be changed from DOS extended ASCII characters to standard ASCII characters for other operating systems. * Comma-delimited and tab-delimited output formats for easy importing into databases, spreadsheets or word processors for further analysis or specialised printing. * Directory sorting can be disabled. * Future proof - directory sizes up to 99 GB are catered for. * Progress indicator as it accumulates file information. PRIVATE use of DirSize is FREE. Please register your usage by sending email to Simon Carter at launch@ozemail.com.au, with your name and address. Paid registration (costing $US 5) is required for use in a business, commercial, government or institutional environment. Please see the end of this file for more information. What will DirSize do for me ? ============================= DirSize shows a graphical tree of the directories on your hard disk. The tree starts from the current directory, or from a directory or directories that you specify. The left column displays the total disk space used by each directory. Directories that contain further sub-directories display summary statistics in square brackets after the directory name. This is very useful for determining the complete size of an application, for example, if you were hunting for an application to remove to make way for a new one. Alternatively, DirSize can be used to find the total size of an application before a backup or copy is made. DirSize automatically detects and displays Windows 95 long filenames. Of course, it will still run under any older version of DOS. Installation ============ Just copy DIRSIZE.EXE to a directory in your path, for example, to C:\DOS. To find out the directories in your path, type c:\> path [Enter] How to use DirSize ================== Typing dirsize /? [Enter] on its own will display usage information. Usage: dirsize [options] Where [options] is one or more of: <directory> Default: Current path One or more directories can be specified as the starting point for DirSize's output. For a DirSize of drives a:, b: and the current directory (c:\windows) type: c:\windows> dirsize a:\ b:\ . Directory names with special characters such as spaces must be entered with double quotes e.g. c:\> dirsize "Program Files" "windows\start menu" [Enter] You can perform multiple DirSize command in a single run e.g. c:\> dirsize /1 c:\ /0 d:\ /nosort Do not sort directory names into alphabetical order (the default). This may be useful if you are comparing DirSize's output to an unsorted listing from the DOS DIR command. /p Do not paginate the output. Pagination pauses after each screenful of output. [Enter] shows the next line, [Esc] exits, [End] scrolls continuously to the end of the output, and any other key shows the next screen full of output. Pagination is automatically disabled when the output is redirected. /size=# Show how much disk space would be wasted if the cluster size was set to # bytes per cluster. # is restricted by DOS to powers of two, but for convenience DirSize allows it to be set to any value. This is useful for previewing the result of a change in cluster size on a set of files. In general, the smaller the cluster size, the smaller the wasted space. /# Default: All levels (255) Limits the number of levels of directories displayed to the given value. Eg /1 will only show the first directory level. The statistics will include all levels, but they will not be displayed. This is very useful if you just need to find out how much total space is in use by an application without caring how it is subdivided into sub-directories. A value of 0 is equivalent to a value of 255 (i.e. all levels). /comma Print the result in a comma-delimited output format suitable for importing into a spreadsheet, database or word processor. /tab Same as /comma above but outputs in tab-delimited format. /nowaste Do not to show wasted space for each directory. /asval Show the actual wasted space per directory rather than as a percentage of the directory's used space. /c<+|-> Control which characters to use for drawing lines. + Uses DOS's graphical line drawing characters even if it detects that its output is being redirected. - Uses portable text line drawing characters even if it detects that its output is not being redirected. This is useful if the result is going to be used on another computer, for example, on a Unix machine or a Macintosh. Note: When DirSize detects that its output is being redirected, it automatically turns off pagination, and selects portable characters to draw lines, such as +, - and |. It does this because the output may be sent to a device or another computer that does not understand DOS's line drawing characters (which are non-portable). When DirSize's output goes to the screen, it uses the DOS line drawing characters. You can override the default behaviour in either case using the /c option Redirecting Output ------------------ DirSize's output can be redirected to any device. For example, to save DirSize's output to the file output.txt, you can type: dirsize > output.txt [Enter] To add DirSize output to an existing file exists.txt, type dirsize >> exists.txt [Enter] To send DirSize's output to the printer, type dirsize > prn [Enter] DirSize Example --------------- The output below was generated from running DirSize in the Program Files directory (in a DOS shell under Windows 95): c:\> dirsize "Program Files" [Enter] DirSize v2.6 Copyright (c) 1993-1996 Simon Carter Total space Wstd Directory name [dir + subdirs total] -------------- ---- ---------------------------------------------- 65,536 94% C:\Program files [215,154,688] 1,310,720 7% |--Accessories [1,835,008] 524,288 32% | +--HyperTerminal 32,768 99% |--Borland [98,500,608] 32,768 99% | |--Common Files [4,358,144] 4,325,376 10% | | +--Bde 4,096,000 6% | |--Database Desktop 229,376 37% | +--Delphi 2.0 [90,013,696] 9,207,808 9% | |--Bin [9,699,328] 491,520 98% | | +--Borland Delphi 2.0 32,768 98% | |--Demos [18,710,528] 5,898,240 35% | | |--Data 32,768 98% | | |--Db [4,292,608] 294,912 91% | | | |--Dberrors 360,448 94% | | | |--Filter 360,448 95% | | | |--Find 163,840 96% | | | |--Fishfact 360,448 89% | | | |--Gdsdemo 294,912 96% | | | |--Lookup 983,040 82% | | | |--Mastapp 425,984 96% | | | |--Navmdi 425,984 96% | | | |--Navsdi 196,608 95% | | | |--Ndxbuild 229,376 91% | | | |--Qbfdemo 163,840 97% | | | +--Qjoin 65,536 95% | | |--Demolbl 32,768 98% | | |--Doc [3,735,552] 360,448 98% | | | |--Autoproj 65,536 91% | | | |--Calendar 229,376 97% | | | |--Cbrowse 65,536 93% | | | |--Dataedit 65,536 96% | | | |--Dbcal 884,736 60% | | | |--Filmanex 917,504 96% | | | |--Graphex 163,840 84% | | | |--Oleword1 163,840 85% | | | |--Oleword2 65,536 95% | | | |--Shape 229,376 94% | | | |--Textedit 163,840 97% | | | |--Vararray 163,840 98% | | | |--Varlock 163,840 84% | | | +--Vartoint 229,376 96% | | |--Imagview 458,752 87% | | |--Ipcdemos 32,768 99% | | |--Oleauto [983,040] 557,056 35% | | | |--Autoctrl 393,216 94% | | | +--Autoserv 425,984 90% | | |--Olectnrs 131,072 98% | | |--Ownerlst 163,840 94% | | |--Propedit 655,360 83% | | |--Quickrpt 884,736 55% | | |--Resxplor 294,912 78% | | |--Richedit 458,752 59% | | +--Threads 1,409,024 67% | |--Doc 30,670,848 2% | |--Help [32,833,536] 2,162,688 6% | | +--Tools 32,768 99% | |--Images [8,355,840] 851,968 9% | | |--Backgrnd 5,341,184 98% | | |--Buttons 589,824 98% | | |--Cursors 229,376 99% | | |--Default 688,128 98% | | |--Icons 32,768 99% | | +--Splash [622,592] 229,376 47% | | |--16color 360,448 38% | | +--256color 9,863,168 58% | |--Lib 1,212,416 96% | |--Objrepos [2,097,152] 360,448 96% | | |--Logoapp 262,144 94% | | |--Mdiapp 262,144 96% | | +--Sdiapp 32,768 99% | |--Ocx [360,448] 327,680 28% | | +--Chartfx 2,293,760 2% | |--Quickrpt 1,048,576 21% | |--Register 557,056 58% | +--Source [3,112,960] 557,056 56% | |--LFNit! 32,768 99% | |--Rtl [1,703,936] 1,671,168 18% | | +--Win 196,608 68% | |--Samples 98,304 35% | +--Toolsapi 1,933,312 16% |--ClickBook 32,768 99% |--Common Files [16,547,840] 32,768 98% | +--Microsoft Shared [16,515,072] 589,824 16% | |--Artgalry 851,968 16% | |--Equation 2,031,616 28% | |--Grphflt 2,293,760 4% | |--Msgraph5 491,520 21% | |--MSinfo 1,572,864 27% | |--MSquery 1,703,936 10% | |--Orgchart 2,883,584 6% | |--Proof 2,031,616 13% | |--Textconv 1,409,024 11% | |--Vba 622,592 22% | +--Wordart 688,128 21% |--Font Assistant 3,047,424 38% |--Games 98,304 85% |--Help Assistant 5,275,648 17% |--Jobint 819,200 25% |--Lviewpro 98,304 62% |--Microsoft Exchange 6,684,672 19% |--Norton AntiVirus [7,274,496] 589,824 51% | +--System 2,326,528 7% |--Norton Commander [2,359,296] 32,768 99% | +--Indexing 9,011,200 9% |--Norton Utilities [15,007,744] 5,996,544 19% | +--System 11,304,960 3% |--Painter3 [15,761,408] 589,824 11% | |--Movies 622,592 21% | |--Nozzles 753,664 8% | |--Sessions 851,968 46% | |--Supplies 1,638,400 8% | +--Tutorial 720,896 15% |--Plus!

What is the "Cluster Size" ? ============================ When your computer places files on a disk (both hard disks and floppy disks), it must use an integral number of allocation units. The size of the allocation units varies depending on the total capacity of the disk. This means that if a file is smaller than one complete allocation unit, it does not fill the entire allocation unit. For example, lets say we have a file that is 300 bytes long. On a floppy disk with an allocation unit of 512 bytes, the file will only occupy the first 300 bytes, but since one entire allocation unit must be used, the remaining 212 bytes are wasted. A file 513 bytes long will occupy 2 allocation units, with 511 bytes wasted. An allocation unit is called a CLUSTER. Floppy drives typically use a cluster size of 512 bytes or 1,024 bytes, so not much space is wasted. Hard disks range from 2,048 bytes (for a 106 MB drive) to 32,768 bytes (for a 1.04 GB drive) and even 65,535 bytes, which means that a great deal of space is wasted. The cluster size gets bigger with bigger disks for two reasons: 1) A DOS limitation that sets an absolute upper maximum on the total number of clusters on a drive (65535). 2) The overhead of managing a large number of clusters consumes a lot of disk space that cannot be used for anything else. The DOS DIR command always shows you the size actually in use by the file - it does not include the extra 'wasted' space at the end of the cluster. This wasted space is sometimes referred to as 'slack' space. Directories use up clusters too ------------------------------- DirSize takes into account the amount of disk space used to store the entries within each directory. Normal file, directory and volume label entries take up 32 bytes each. Long filename entries can consume between 1 and 32 additional directory entries (each of 32 bytes). Even empty directories use a minimum of one cluster - for the current directory "." and the parent directory ".." entries. The root directory always consumes a fixed and pre-determined amount of disk space which cannot be reclaimed, and DirSize excludes the number of entries in the root directory from its calculations. DirSize does not take into account the size of entries that are no longer being used. This means that a directory that has had many files deleted may display a size lower than that actually in use. DOS never reclaims this extra space unless you delete the directory. To reduce the amount of disk space used by directories, remove directories that do not contain any files. Also, if you delete a large number of files from one directory (particularly directories containing long filenames), move the files to a new directory, remove the old one and then rename the new directory to the original name. Lost clusters ------------- Clusters can become orphaned when DOS is unable to complete changes to the disk, for example, when you are forced to reboot your machine or when the power is turned off accidentally. These clusters cannot be used until they are identified and reclaimed. Use the DOS CHKDSK or SCANDISK command to reclaim lost clusters. Lost clusters are considered to be used. Reducing wasted space ===================== What about Disk Compression ? ----------------------------- Disk compression programs like Stacker and DoubleSpace are able to make use of the wasted space because they take on the responsibility of storing the files themselves. By doing so, they overcome DOS's integral cluster size limitation. DirSize's space wasted information may be invalid on volumes controlled by these programs, and on some later versions of file servers. What about archives ? --------------------- Storing collections of files in a compressed or uncompressed archive saves space, because by grouping all of the files into one large file, only a small amount of space is wasted. The archive program uses its own format to store the files without wasting space. Partitions - decreasing the cluster size ---------------------------------------- Partitions subdivide a physical disk drive into a number of logical drives. For example, a 500 MB hard disk could be partitioned into two 250MB partitions, C: and D:. The advantage of doing this is that the cluster size can be smaller, and in general, the amount of wasted space will be smaller. The disadvantage is that it takes time to set up (since you have to move ALL of your data off the hard disk in order to partition it, unless you have a program that can re-partition on the fly), and you have to remember which drive your programs are on, and manage space across two drives instead of one. For more information on partitions, see the DOS FDISK command. New features/Revision history ============================= Date Version Changes Made 14-Oct-96 2.6 Added wastage percentage/value to display. Changed display format. Added wastage information for each directory. Increased speed (again). Added comma-delimited and tab-delimited database output formats. Added the actual size of the entries in each directory to the total size count. Added ability to limit directory depth and to specify multiple directories with separate parameters for each. 24-Jun-96 2.5 Reduced stack usage further. Added /nosort, /size=# and /p option. Added automatic pagination. Fixed bug for paths longer than 68 characters. Re-instated stack checking. 13-Jun-96 2.4 Increased stack limit to 64K, and reduced stack usage. This means that you can list directories that are much deeper than before. Appreciably faster (11 seconds compared to 14 for a complete display of a 1.1 Gb drive). Now only shows usage information if /?, ? or -h given as first parameter. Email and address changes. 27-May-96 2.3 Documentation update. 8-May-96 2.2 Shows usage information if no parameters are provided. Fixed bug in long filename functions that prevented them from working under some circumstances. Fixed bug in file size rounding up function, which made files that were an integral number of clusters long one extra cluster long. Documentation update. 28-Apr-96 2.1 First release. 3-Jul-93 1.0 First created and used. Registration ============ PRIVATE use of DirSize is FREE.
