defrag script for sysinternal contig

My Music folder contains Chinese songs.

C:\ProgramData\Malwarebytes\MB3Service\rules.mbdb is in 113 fragments

I ran the script several times. There are still 113 fragments

Code:

C:\ProgramData\Malwarebytes\MB3Service\rules.mbdb | 113 |  72  88  88  21,999,616 (21.0 MB)

I'll take a look, but I don't think Contig supports Unicode, so that could be problem.

The script is not complete. So far, it just has code to gather fragment details and I don't think that part is right yet (see my post regarding fsutil file queryextents).

The defragmentation has made no difference.

Code:

C:\Windows\system32>"E:\Testing\Contig64.exe" "C:\ProgramData\Malwarebytes\MB3Service\rules.mbdb"

@einstein1969 Can you explain why you want the results from the command "fsutil file layout"? The "Allocated size" items are always a few very small numbers, followed by the entire size of the file. It does not show the fragment sizes.

the problem is with contig output which does not use unicode but writes in codepage 1252.

There is a solution for those files which are not covered by codepage 1252, I've already thought about it. I just didn't put it into practice because it could be a lot slower.

But I'm working on it.

However the contig in the defragmentation phase then seems to work

Code:

Processing N:\Victoria536\LNG\???????.Lng:
Scanning file ...
Scanning disk ...
File is 4032 physical clusters in length.
File is in 122 fragments.

Found a free disk block at 844833794 of length 4583 for entire file.
Moving 4032 clusters at file offset cluster 0 to disk cluster 844833794
File size: 16515065 bytes
Fragments before: 122
Fragments after: 1

Actually, individual extents (fragments) would be needed as you tried to do before. But in order not to complicate things immediately, I started to obtain a parameter (the allocated disk size) to be able to make decisions, for example, on the defragmentation order.

the actual file size does not always match the size allocated on the disk. For example sparse files or compressed files can take up much less space. So in this case the decision of how to defrag (the order) can change.

To find out the size actually allocated I used a method that is not perfect. Now I'm writing version 0.0.4 which finds the right stream, which is the stream with no name and type/attribute (0x080) ie "::$DATA".

The output of the fsutil command if you see returns all the streams and for each stream it indicates the allocated and real size. Generally the fourth element related to the stream ::$DATA is the allocated size. In fact, the script should be changed to search this way regardless of the language.

I'm working on it...

at the moment the powershell script work fine how the dos batch script 0.0.3 !!!

@einstein1969 Thanks for the explanation. I look forward to seeing the final script. I don't need to defragment (I only have an SSD) but I always enjoy seeing how the code works. Thanks for sharing!

I found that "Contig.exe" alone can do the job. "Contig64.exe" is unneeded.

"E:\Testing\Contig.exe" "The file path"

Code:

C:\Windows\system32>"E:\Testing\Contig.exe"  "C:\Users\Matthew_Wai\AppData\Local\Microsoft\Windows\Notifications\wpndatabase.db-wal"
