(Skip to Maintaining the Windows XP Workstation if you have

Windows XP)

Cleaning up Temporary Files

After the ChemStation has been used for some time, temporary files may

accumulate in the directory specified by the TEMP Variable. These files are

generally left open when Windows is abnormally terminated. The files generated

have a .tmp extension. These files should be deleted to maintain computer

efficiency.

1) Close all programs.

2) Go to the Start button then Search and select For Files or Folders….

3) In the Search for Files or Folders named: field, type *.tmp.

4) In the Look in: field, find your hard drive, C: or Local hard drives.

5) Select Search Now.

6) After a few moments, the files will be displayed. Highlight the first file.

Using the Shift key and the left mouse button, highlight the last file. Press the

Del key to remove the files. Remember that you will have to empty them

from the Recycle bin as well.

Repairing the Disk

Windows 2000 includes a utility to check disk integrity. Among the errors that

may be fixed are lost clusters and cross-linked files. Error-checking can move

your data from bad sectors as well. You must be logged on as part of the

administrator's group to run this utility.

1) Log on as the administrator. Press CTRL-ALT-DEL simultaneously. Log on

as the administrator. The password is agilent. Or check with your instructor

for the correct password.

2) Double click on the My Computer icon and right-click on the drive icon for

C:. Select Properties to display a selection box.
