problem if not administrator

[tof]

You say users can also run JkDefrag, but then it can only defragment/optimize the files for which the user has "full control"

But JkDefrag needs absolutely "full control" permissions, or it don't work.

I tested it and it's not possible, have you got a solution for me ?

thanks
(sorry for my english)

It sounds like your system administrator has changed the default permissions of your harddisk, perhaps to prevent you from accidentally formatting it. You will have to ask him to change the permissions. JkDefrag does not need full access to all files, but it does need full access to the disk.

Thank you for the response !
But... I'm the administrator, and all users have full access to the disk...
I think it's another problem, but what ?....
thank you

Two of the operations that are used in the defragmentation process require a handle to a volume. Only administrators can obtain a handle to a volume, so only administrators can defragment a volume. An application should check the rights of a user who attempts to run defragmentation software, and it should not allow a user to defragment a volume if the user does not have the appropriate rights.

ok  i think like you... but the documentation say :

 Permissions
    JkDefrag needs "full control" permissions to all files that it must defragment/optimize. On a default Windows system the "administrator" userid has full permissions to all files. Users can also run JkDefrag, but then it can only defragment/optimize the files for which the user has "full control".

so, the last phrases is wrong ?

thank you,

Well, if you want to put it like that. Perhaps "incomplete" is a better word. The doc only discusses access to files, not to disks. I will add a little bit of text about always needing full access to disks.

sorry for my poor English if i don't use the good words !
but i want to say that my users in the "domain" have full control to the disk, so the problem is not here...
if the user is not administrator, JKDefrag will not work.

JkDefrag is governed by the standard Windows permissions. If a user has full permissions to a file (read, write, delete) then JkDefrag can defrag the file. There are no special circumstances or anything like that, the program does not need full permissions to all the files on a disk. To put it differently, you are experiencing a Windows permissions problem.

Perhaps a tip: create a special userid for JkDefrag and give the userid Administrator permissions. Then create a schedule in the Task Scheduler and specify the userid. The program can then run without the users needing full access to all files.
