Hi, list. I posted this question to KDE forum, but still couldn't get answers after some discussion. When I plug in my USB drive, it was mounted automatically. Then KDE tried to open the mount point folder with kio_file, and replied an "/mnt/removable is a folder, but a file was expected." error message. I tried hard to find where the setting is, but in vain. I also hacked into the kdelibs/kio code and inserted some debug messages. The following is part of the debug messages from KDE. <debug messages> kio (KDirListerCache): [virtual void KDirListerCache::FilesChanged(const KURL::List&)] only half implemented kio (KDirListerCache): [void KDirListerCache::updateDirectory(const KURL&)] media:/ media kioslave: MediaImpl::slotMediumChanged:sda1 media kioslave: MediaImpl::slotMediumChanged: updating mp_mounting media kioslave: MediaList::list() media kioslave: () remote kioslave: RemoteDirNotify::FilesChanged remote kioslave: RemoteDirNotify::toRemoteURL(media:/sda1) remote kioslave: result => KURL() kded: HomeDirNotify::FilesChanged kded: HomeDirNotify::toHomeURL(media:/sda1) kded: result => KURL() kded: SystemDirNotify::toSystemURL(media:/sda1) kded: system:/media/sda1 kded: MediaNotifier::onMediumChange( sda1, false) media kioslave: MediaList::findByName(sda1) kio (KDirListerCache): [virtual void KDirListerCache::FilesChanged(const KURL::List&)] only half implemented kio (KDirListerCache): [void KDirListerCache::updateDirectory(const KURL&)] media:/ kio (KDirListerCache): [virtual void KDirListerCache::FilesChanged(const KURL::List&)] only half implemented kio (KDirListerCache): [void KDirListerCache::updateDirectory(const KURL&)] system:/media media kioslave: MediaDirNotify::toMediaURL(system:/media/sda1) media kioslave: MediaList::list() media kioslave: () remote kioslave: RemoteDirNotify::FilesChanged remote kioslave: RemoteDirNotify::toRemoteURL(system:/media/sda1) remote kioslave: result => KURL() kded: HomeDirNotify::FilesChanged kded: HomeDirNotify::toHomeURL(system:/media/sda1) kded: result => KURL() kded: SystemDirNotify::toSystemURL(system:/media/sda1) kded: KURL() kio (KDirListerCache): [virtual void KDirListerCache::FilesChanged(const KURL::List&)] only half implemented kio (KDirListerCache): [void KDirListerCache::updateDirectory(const KURL&)] system:/media kdeinit: Got EXEC_NEW 'kio_file' from launcher. kio (KLauncher): kio_file (pid 32389) up and running. kio_file: Starting 32389 kio (KIOJob): error 9 /mnt/removable kio (KIOJob): error 9 /mnt/removable kio (KIOJob): error 9 /mnt/removable kio (Scheduler): Scheduler: killing slave 32377 kio (Slave): killing slave pid=32377 (file://) kio (KIOJob): Job::kill this=0x80b38e0 KIO::TransferJob m_progressId=0 quietly=true kioexec: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! kio (KIOConnection): ERROR: Header read failed, errno=104 kio (KIOConnection): ERROR: Header has invalid size (-1) kio (kioslave): SlaveBase::waitForAnswer has read error. kio_file: Error during 'put'.

Could anybody please give me some hints about: 1. How could I modify the behavior when USB plug in, change from "opening folder" to "Do nothing"? 2. Why does KDE use kio_file to launch the mount point folder? I cannot find where the behavior is defined. Is it a bug or just misconfigured? Thanks for you help. Regards, Franklin
