WinXP .mov thumbnails (61) Thu, Mar 13, 2008
My Panasonic digital camera records movies in .mov format.  I don't know why, and I can't change it.  The problem is that Windows XP doesn't show thumbnails for .mov files, which is an issue when I want to look through my pictures and videos with the whole "View → Thumbnails" option selected.  I searched the internet for a solution several months ago and didn't find anything.  I just searched again this morning and found a pretty simple solution, though I'm surprised at how relatively obscure it is and how hard it was to find.  Here's what you need to do: 
  1. Download QuickThumb.dll from here.
  2. Copy to C:WindowsSystem32.
  3. Go to Start → Run and type regsvr32 QuickThumb.dll.
  4. If there's an error, download msvcr70.dll from here and repeat steps 2 and 3.
  5. Go to a directory with .mov files, switch to thumbnail display, and possibly press F5 to refresh.
I can't believe I didn't discover this sooner.  That really annoys me.  And it annoys me that the internet wasn't much help for a while. 

(I'm hosting all necessary files here.) #technology

The .txt you include is a bit more accurate. I believe both files need to be places in c:windowssystem32 and then the command you run is regsvr32 QuickThumb.dll; WITHOUT '/u' (which i think is the switch to UNregister..)
Thanks a lot for putting this together. Very handy :)

Dave Wed, Jul 02, 2008
Hmm, you're probably right.  I changed it in the post above.  Thanks.

John Fri, Sep 19, 2008
How cool is this!
Struggled without for years.
Makes life so much easier!

Nathan Tue, Oct 07, 2008
I just wanted you to know that you probably just saved me a freelance video editing job... I had been struggling with this for days and was almost ready to give up. Thank you so much!

Dave Tue, Oct 07, 2008
Awesome!  Glad my little discoveries are actually helping people.

Shaun Sat, Oct 25, 2008
Fantastic. Thank you.
One problem though: when using the Search function in Explorer (with View set to Thumbnail) Explorer crashes just as the last thumbnail is displayed. (Windows XP)

Dave Mon, Oct 27, 2008
Hmm that's a shame.  I should've said at the beginning that I can't guarantee it won't make your computer blow up.

For video files you can use Thumbnailer from CapTrue. It is a WMP plugin, and when you using it you can assign ANY frame of your video as a thumbnail. Works with .mov and .mkv either.

Thanks!!!!!!!!    por fin encontré la solución a mi problema...!!!!
problema para ver vistas miniatura en el explorador de windows xp, se ralentiza, video .mov

muhammed Fri, Jan 09, 2009
thanks for sharing such great idea i was suffering for decades  !

Ron Sat, Jan 17, 2009
Thank you for this

Matthew Thu, Jan 29, 2009
Thanks so much! I have wanted to continue editing home video clips of my children, and with my new Casio camera/video camera only producing .MOV files, I was a bit lost on how to continue without the painstaking task of viewing each clip "blindly" to find the right ones. This worked! You've saved me hours...and nerves!! ;-)

Shawn Thu, Jan 29, 2009
I'm getting an Explorer error in quickthumb.dll everytime I attempt to set the view mode to thumbnails in explorer. I put the files in windows/system.. how can I unregister quickthumb.dll? This is annoying...

Dave Thu, Jan 29, 2009
I believe you unregister with regsvr32 /u QuickThumb.dll.

Nigel Sun, Mar 08, 2009
Brilliant, thanks.
I have been relying on seeing the thumbnails through Google's Picasa but this is better.

panojack Fri, Mar 13, 2009
Not working. Both QuickThumb.dll and RealThumb.dll crash my WinXPSP2 :((

bubu Mon, Apr 27, 2009
Thank you!
It's really useful for my animations. Thanks.

Jackie Mon, Jun 22, 2009
says I cannot open the .dll file.  What am I doing wrong?

Dave Mon, Jun 22, 2009
You're trying to open the DLL file.  Don't.  Follow the directions.

Deano Sun, Jun 28, 2009
Brilliant, had trouble installing in Vista had to turn off UAC to get the dll to register, you may want to add that to the instructions

florex78 Sat, Jul 04, 2009
Thanks man .... this really helps me a lot . Again ... many thanks for this post .

Zane Wed, Jul 29, 2009
I found this dll yesterday and tried and it crashed stating "the instruction at "0x01e827de" refrenced at "0x00000020".  The memory could not be "read"." with different addresses every time.  It seems to crash when it tries to paint the thumbnails.  I noticed when I copied MSVCR70.dll there is one already there that is 336kb (as opposed to the one you provide which is 300kb).  First I copied both files to system 32, registered quickthumb.dll then tested with a crash.  Then I tried with the origional 336kb MSVCR70.dll, unregistered and registered quickthumb.dll with a crash.

I am running SP3.

I appreciate any help getting this to work.  I looked into the UAC thing but that looks like a vista issue.

Dave Wed, Jul 29, 2009
I have no idea.  I'm just the messenger.

FinnyDD Fri, Oct 02, 2009
Does this work for Vista x64Bit?  Any help is appreciated.

sb Fri, Jan 22, 2010
cheers works a treat!

X Tue, Feb 16, 2010
almost two years later, still works XD thank you

villa Thu, Feb 18, 2010

Sam Tue, Mar 23, 2010
Thanks so much!!! Works great!!! Respect Yoooo!!

Sith Sat, Apr 10, 2010
Works fine for all movs,exept for hd=(It crushes win explorer,still thx)

Rick Mon, Jun 07, 2010
Hi.. downloaded today QuickThumb.dll v0.21 and placed it in C:WINDOWSSYSTEM32 folder. Upon viewing my pictures folder containing .MOV files from my Kodak camera, it crashes windows Explorer almost immediately. I'm presently using XP sp3. I'll Google some more.

Mac Thu, Jun 10, 2010
Works like magic!! Million thanks~

Orelia Sun, Jul 04, 2010
Work! Many Thanks!

sharoni macaroni Tue, Jul 06, 2010
Windows XP Professional, SP3  -- worked like a CHARM~  Thank you.

Viv Wed, Aug 11, 2010
Thank you, this worked for me!

steve zabrisky Thu, Nov 04, 2010
works perfect~!  makes my workflow 100x more efficient.

Edub Tue, Nov 23, 2010
Same deal with me, SP3 installed and Explorer crashes to blank desktop

Delta Echo Tue, Dec 21, 2010
XP Pro SP3 using "regsvr32 QuickThumb.dll" downloaded right to /windows/system32  works like a charm.  Excellent project, excellent use of system resources for a tweak that SHOULD have been in XP all along!  Cheers!

Tim Thu, Dec 30, 2010
Thank you so much for posting this.  Very useful!

Erik Sun, Feb 27, 2011
Can't remember a moment where I was as happy as a few minutes ago.
IT WORKS!!!!! Finally after 8 years the solution.
Saves me a hell lot of conversions and search actions now.
btw: I only copied the QuickThumb.dll in system32 because the existing file was newer
and it works perfect.
Thanx from Holland, haha

Stefan Mon, Mar 07, 2011
This works like a charm. Installed it under XP SP3. No msvcr.dll needed. Worked instantly.Thank you very much.  Now I need a simple way to cut .mov files (avi. files i simply cut in VirtualDub, but with .mov this won't work)

Wes Nile Sun, Mar 13, 2011
It really worked! Thankyou so much for posting this. I was looking for 2 days.

miguel Mon, May 30, 2011
hey I did exactly and have an error, it says that quickthumb.dll is not an executable file...
I am runing windows XP 64bit

Manjula Wed, Jun 15, 2011
Brilliant. it works for me xp, sp2. I did almost everything and nothing worked till this post. Thanks Dave..

Mike Thu, Jun 23, 2011
This procedure will crash Windows Explorer.  Really not recommended.  I'm a bit skeptical of those that say it worked.

Shawn Fri, Jun 24, 2011
You should be weary-- because it doesn't work.

Erik Fri, Jun 24, 2011
With me it still works on 2 computers (Windows XP 32Bit SP3)
No crash of explorer etc. or other issues. Just needed the Quickthump.dll file

Maybe it has to do with the 64bit versions of WindowsXP
My next install will be Windows7 so this issue will be solved.

@Mike: If it doesn't work for you, sorry. You have to find an other solution.
But no reason to be skeptical on those of who worked the patch for.
I'm also not sceptical of your copy-paste capabillities ;-)
It still was worth the try

Mike Mon, Jun 27, 2011
I am skeptical only because it certainly doesn't always work (read those reports in every forum that discusses this dll) and crashing Explorer is a very serious potential side-effect, but in hindsight I agree with you that I should not have used that word in the context I did, as it infers the (whole) truth was not told, I apologize.  What I'm inclined to believe is that for those users in which this dll does work there is some additional file(s) present which allow this to work for them, otherwise how could this work for some, and absolutely crash Explorer for others?  You see, it didn't just crash Explorer once (while being implemented), but will not allow Explorer to run until the dll is unregistered.  For some users this would be considered catastrophic.

I too, have tried this dll on several 32bit XP SP2 and SP3 machines, although always unsuccessfully, and always with the crash.  What I would like to see is a complete and reliable solution to this issue.  If Quicktime or another MOV codec is installed this registry entry can work:


This registry entry does not, and can not, cause Windows Explorer to crash, so is ultimately more secure(reliable) than the dll, but again, an appropriately installed codec is required.  I accidentally came back to this page today because of my ongoing search for a reliable solution.  I'm glad I did, because the more people discuss this issue, the more likely a 100% reliable solution (if there is such a thing) will be found.  I think Mike B, the author of this dll, should have gone a bit farther than "...your results may vary" in his warning.

Erik Wed, Jun 29, 2011
Mike,I agree with you. I also was searching the web for a solution. Installed numerous programs and
codec's. (k-lite codec pack etc) but nothing worked for me.
This DLL did the job for me. Don't know why.

But to play save it's better to install a MOV codec and add that registrycode of your's
Only be carefull when you edit your registry, you could end up in the same crash...
Not for you, but for some people who are not known to a registry editor.
But I added it into my fix list for my next xp install, so thanx.

Defenitily not sceptical of your capabillities, thumps up !! Apologizes on my side ;-)

Paul Tue, Jul 05, 2011
Dave you're awesome. Over three years later your solution still works as a charm.  It took a minute or two to go through the entire process.  No issues.  Thanks.

Filip Sun, Sep 11, 2011

Alex Wed, Oct 19, 2011
Fantastic, cheers for this!

Mark Wed, Nov 09, 2011
Thank you so much, this has been a major irritation since I got an IPhone

Kevin from Germany Sat, Dec 03, 2011
Dude!!!! :D  the shiat! I´m so greatfull for your help! :-) it actually worked out ;D

Stefan Sat, Dec 03, 2011
I had to uninstall (unregister) it again, because my explorer was crashing when i got into folders with .mov files. First it was working but since 2011 I got problems. I dont know exactly why, but i think there a certain types of .mov files, that it can't handle... =(  Would be nice if the bug could be fixed, or at least if the explorer didnt crash (no matter if there is no thumbnail)... greets

Christy Sun, Mar 04, 2012
was skeptical at first... Windows XP SP3 works like a charm...

Richi near Frankfurt/M. Thu, Apr 05, 2012
Thanks Dude, that solved my sorrows. Windows sucks in that way, your tip works great! First time i used those kinda codes, I feel like a real Computer-Nerd ;-)))

Greg Sat, Jun 16, 2012
Thanks for the simple fix, it worked much better than some of the other methods out there which often recommend manual alterations to the registry.  I can see my MOV thumbnails now which makes working with many small videos a lot faster for editing purposes.  Thanks again.

Bob Sun, Apr 20, 2014
Dude you are the man!!!  I had been looking for 3 hrs and finally found this, the light at the end of a long tunnel.

Jason Tue, Mar 17, 2015
Crashes Windows Explorer Win XP Pro SP3.

Terry Thu, Sep 24, 2015
Same problem here. Crashing Win Explorer in XP Pro (SP3) in certain folders. Some of the MOV files do have thumnails and some don't. I'm guessing that the latter are reacting with QuickThumbs to cause the crash.
