MTP File Transfer crashes Explorer.exe

8 posts in this topic

Windows 7 Professional (x86)

Sony Vaio VGN-FE690P

Intel T2300 1.67 GHz

2.00 GB RAM

Attempting to transfer/ modify files on USB device crashes Windows Explorer.exe. This only occurs with MTP transferring, i.e. camera, phone, tablet. The folders on the device can be viewed, but can not be deleted or items transferred to a local folder without Explorer.exe crashing.

Cameras can transfer files using "Import Picture Wizard"

MiniDump.dmp available

Reference this POST, but to no avail.

Thanks in advance.

please download this reg file from my SkyDrive:


and make a double click on the file to import it. If you can't do this, run regedit.exe and import the registry file there!

When the Windows Explorer crashes, Windows Error Reporting Service creates a dmp file under C:\Localdumps. Please upload the dump file (compressed 7z or RAR to reduce the size) to your public Skydrive folder and post the link here. I take a look at the dump with the Debugger, maybe I can see the cause.

After you generated the dumps, download and import this regfile:


to stop the dump creation.

Afterwards, I used shexview.exe from http://www.nirsoft.net/utils/shexview.html to edit which Explorer shell extensions were enabled. I excluded all MS shell extensions from the list and Disabled the remaining items. I can not narrow down which shell extension was causing Windows Explorer.exe to restart right now, due to devices not being available. I will test my findings tomorrow, but each time a new shell extensions is enabled I will have to restart. This will take some time.....

WinZip seems to cause it:

MagicAndre1981 - Thank you for the quick replies. I can confirm that disabling the WinZip shell extension caused the issue to occur no longer. I can transfer files from any MTP device now. By doing this I am still able to use WinZip as normal, except for the Right-Click feature for Unzipping/ Adding items. If any one else has similar issues, please go to the Shell Ex View link above and follow the steps provided to Disable all non-MS shell extensions. (They will be in pink) This will help greatly if you are not familiar with .dmp files and analyzing them.

Thanks again.

I have a Sony like this one HERE and at first connection to a PC, it is recognized as MTP. What I do, since it has USB, is manually change the driver in Device Manager to the stock USB Mass Storage Device and I never have problems transferring data. USB charging is also available regardless of the change of driver.

Just a tip you might find useful.
