I've noticed quite an accumulation of files in my base users directory on Windows Vista (C:\Users\username). I really hate having files littered across my hard drive unnecessarily.

Some of them seem to be related to Motorola--I have a Motorola RAZR V3m that I connect to my computer via USB. Here's a sampling of the file names:

  • 1236237042-oem13.inf
  • MCCI_BUS.INF
  • MCCI_MDM.INF
  • MCCI_SDM.INF
  • mqdmbus.sys
  • mqdmcmnt.sys
  • USB_CMCS_2000.INF
  • USB_MOT_A1000.INF
  • USB_MOT_BRIT.INF
  • USBMOT2000.INF
  • usbsermpt.sys

How did these files get here and are they safe to delete?

These files are for the Motorola phone:

  • mqdmbus.sys
  • mqdmcmnt.sys
  • USB_CMCS_2000.INF
  • USB_MOT_A1000.INF
  • USB_MOT_BRIT.INF
  • USBMOT2000.INF
  • usbsermpt.sys

And these seem to be from Sealthbot:

  • 1236237042-oem13.inf
  • MCCI_BUS.INF
  • MCCI_MDM.INF
  • MCCI_SDM.INF

Whether or not you still use these programs will determine if you should delete them.

It has to do with how Vista installs things. If you have a lot of USB devices, you will have a lot of those files.
