Optimize NTFS index after large number of file deletions?
Posted on 2005-04-15
Setup: Dell 2.4 Ghz, 80 Gb Hard Drive, Windows XP Home w/service Pack 1 and all updates except SP2.
Background: I recently had a major project which involved downloading Zip files, unzipping 1.8 MILLION small files, renaming all said files (changing extension - these are basically small CSV text files), doing some QBASIC programming which extracted the data and created summary files, and deleting the 1.8 million files. I have emptied my Recycle Bin, purged files in Norton SystemWorks "Protected files", cleaned out the Temp directory (Both one in Windows and one in Docs&settings\..\Local Settings).
I find the computer is real sluggish - I will click on an open app on taskbar and the machine doesn't immediately go to that app, it takes longer when looking for files in Windows Explorer, etc. The calc speeds (if in Excel for example) don't seem to affected - just the screen refresh and file related functions. It is behaving a lot like if you have too many files in the recycle bin.
My understanding is that NTFS uses a journal approach to keeping track of file locations. If this is true, is it possible that the journal has just gotten too big and needed reindexed? However, if that is the case - why would screen refreshes be impacted?
Not sure where to go - anybody have any ideas?
P.S. - I will run Norton SpeedDisk on the unit as soon as possible - have not had the opportunity yet.
