About folder LEXICON

Hi all,

Would delete this folder LEXICON (and let it re-build itself again) would make the mail database more tidy ?
I found recently the IMAP Gmail is slow (lagging) so want to see if by deleting LEXICON folder could be a work around.

Thank you
Edmond.

Hi Burnout426,

Your other post from above saying these 2:

* Move the file/folder to another drive and then move it back.

* Right-click on the file/folder and choose "copy". Then, right-click on the folder it's in and choose "paste" to create a copy of the file/folder. Then, delete the original. Then, rename the copy to have the name of the original.

Would that make the magic by moving the mail folders from one place to the other, then move it back to where it's originally was ?
If yes, why that so simple & the theory is ?

Thank you
Edmond.

Moving the mail folder from one drive to another or copying the mail folder and pasting the copy next to it and deleting the original will work. But, the defrag program has the potential to do even better.

If yes, why that so simple & the theory is ?

First, when you move a file from one spot to another on the same drive, the location of the file's data on the disk doesn't change. The pointer (what you see in the OS for file) is just shown in a different spot. But, when you move a file off the drive its data is deleted (well, marked as erased where other programs can write over it) where if you move/copy the file back to the drive, a whole new copy of its data is written to the drive.

So, the more a file is written to (appended to and increased in size for example) the more its data gets spread across clusters on the disk. Since the next available cluster may be used by something else, parts of the file will be written to other clusters. In short, the file's data isn't contiguous on disk and gets worse the more you write to it.

Doing the copy deal will write a copy of the file's data to new (available) clusters, which gives a better chance (but not necessarily 100% chance) that all the clusters used by the file will be contiguous. This makes performance better because the hard drive head doesn't have to jump all over the place to access the file's data.

But, a good defragmenting program can do better than the copy way as it can move a file's contents so that all of the file's content is spread across contiguous clusters.

But, it will get fragmented again eventually.

Great !

I prefer defragment as this seems to me the most GUARANTEE method.

Thank you
Edmond.
