- About Unfrag:
- If you're a Windows 95 or Windows NT user, you may be losing
- precious disk space without even knowing it. Most hard disks
- today contain compound files created by Microsoft Word,
- Microsoft Excel, and other applications that support Object
- Linking and Embedding (OLE). Compound files, when fragmented,
- can waste a lot of disk space. This issue's free utility, which I've
- named Unfrag to distinguish it from conventional hard disk
- defraggers, hunts down compound files and unfragments them for you.
-
- Usage:
- To install Unfrag, copy Unfrag.exe to the folder of your choice.
- There are no auxiliary files or DLLs to copy, and Unfrag writes
- nothing to your system's registry. The entire program can be
- uninstalled simply by deleting Unfrag.exe.
-
- When executed, Unfrag displays a simple dialog box. To begin
- the unfragging process, enter a file name or file name specification
- (for example, *.doc) in the Named box and a path name identifying
- a drive or folder in the Folder box. If you'd like Unfrag to unfrag
- compound files in the specified folder and its subfolders, check the
- "Include subfolders" box. Then click the Unfrag button.
-
- When executed, Unfrag displays a simple dialog box.
- To begin the unfragging process, enter a file name or
- file name specification (for example, *.doc) in the Named
- box and a path name identifying a drive or folder in the
- Folder box. If you'd like Unfrag to unfrag compound files
- in the specified folder and its subfolders, check the
- "Include subfolders" box. Then click the Unfrag button.
-
- As the unfragging process runs its course, Unfrag keeps
- you apprised of its progress with a dialog box.
- "Files examined" indicates how many files have thus far
- been found whose names match the pattern in the Named
- box. "Compound files found" tells you how many of those
- files are compound files. Each time it identifies a compound
- file, Unfrag unfragments the file, compares the new file size
- to the old, and adds the difference to the "Bytes saved"
- value displayed in the dialog. Note that not all compound
- files shrink when they're unfragmented because some have
- no dead space in them. Don't be alarmed if "Bytes saved"
- doesn't increase every time a compound file is processed.
-
- You can cancel an unfragging operation at any time by
- clicking the Cancel button. When unfragging is complete,
- the Cancel button changes to an OK button. The dialog
- box remains on the screen until OK is clicked so you can
- review the results of the unfragging process. You may
- invoke online help for Unfrag by selecting "Help" from
- the System menu or pressing function key F1.
-
- Unfrag supports a full set of command line options that
- enable it to be run without user intervention. This feature
- will come in handy if you wish to use System Agent or a
- similar utility to schedule the launch of Unfrag and let it
- run unattended. Unfrag's command-line syntax is:
-
- UNFRAG pathname [/S] [/R]
-
- where pathname is the path to the folder containing the
- files to be unfragged, /S tells Unfrag to process files in the
- specified folder and its subfolders (equivalent to checking
- the "Include subfolders" box in the Unfrag window), and
- /R means "Run now"-the command-line equivalent of
- clicking the Unfrag button in Unfrag's main window.
- The pathname parameter may include a file specification
- (for example, *.doc). Be sure to enclose pathname in
- quotation marks if the path name includes spaces.
- Otherwise, Unfrag will interpret a space embedded in a
- path name as a separator character marking the end of a
- command-line parameter.
-
- A few examples will help to clarify Unfrag's command-line
- options. Suppose you're using System Agent to launch
- Unfrag in the wee hours of the morning, and you'd like
- Unfrag, when started, to unfrag all the .doc files on
- drive C:. Here's the command to use:
-
- UNFRAG C:\*.DOC /S /R
-
- If you'd rather have Unfrag unfrag all the files in drive
- C:'s My Documents folder and its subfolders, use this
- command instead:
-
- UNFRAG "C:\My Documents" /S /R
-
- To restrict Unfrag to just the My Documents folder
- (no subfolders), omit the /S switch:
-
- UNFRAG "C:\My Documents" /R
-
- Be sure to include a /R switch if you want Unfrag to
- start processing files immediately. If you omit this
- switch, the options you entered on the command line
- will show up in Unfrag's window (for example, the
- "Include subfolders" box will be checked if the
- command line includes a /S switch), but unfragging
- won't begin until the Unfrag button is clicked.
-
- Note: The file UNFRAG_S.ZIP contained in UNFRAG.ZIP is the
- source code for Unfrag. This will only be of interest
- to you if you are a programmer, and can be discarded
- if you choose.
-
- Support for Unfrag:
- Support for the free utilities offered by PC Magazine can be
- obtained electronically in the discussion area of PC
- Magazine's Web site. Go to the URL
- http://www.pcmag.com/discuss.htm/ and select the Utilities
- area. You can also access the Utilities discussion area from the
- utility's download page. The authors of current utilities
- generally monitor the discussion area every day. You may
- find an answer to your question simply by reading the
- messages previously posted. If the author is not available and
- you have a question that the sysops can't answer, the editor of
- the Utilities column, who also checks the area each day, will
- contact the author for you.
