Windows 7: thumbnails slow

04 Dec 2010   #11

Windows 10 Pro X64

I just tried this with a folder thta has 370+ pictures in it (.jpg). First time I opened it and changed the view to large icons, it took about 45 seconds to populate. I closed out, started Windows Explorer again and this time when I looked at that folder, it populated in under 5 seconds.

How many pics are in one of the folders you see this problem happening?

Ok Great news! No need for SSD or any other new hardware. Ive been pounding away at searching for a solution all day and found one.

UPDATE: Read my next post. This fix below has limitations.

Google Stop Prevent Windows 7 From Deleting Thumbnail Cache

Works excellent! The thumbs are instantly there when I select a folder like I remember it to be in XP. No more waiting for them to redraw. Its instant on my machine. Like BAM! instant. Wow what a relief that is.

I noticed looking at
the thumbcache_96 file was only 2,736KB before the tweak, (that was after browsing tons of folders) now just browsing a few folders after the tweak its grown to 872,736KB and it continues to grow which is a good sign. I dont care if it grows to be 5 gig. It works.

Interesting find. I've made the change, will see what affects it has over time.

Glad you got it fixed and thank you for posting your fix. Here is the link to the article.

Windows 7 Home Premium 64bit.

Its a bust@! I made a mistake.

The thumbcache_96 file is maxed at 449MB, then it starts making tmp files under a folder "ThumbCacheToDelete". I glanced at my thumbcache_1024 file which is over 2GB. I was looking at the wrong one. Thumbcache_1024 is made by Window Live Photo Gallery

There is no fix but it helped for 449MB of thumbs anyway. Hope MS fixes this incredible annoyance.

Im just going to leave it as is and see what happens over the next few days.

Ah well, sounded good. I'm guessing the four different thumbcache_nnn.db files represent thumbnails for those DPI values. Can anyone confirm this?

Windows 7 Home Premium 64bit

Hello again, I might have a solution for you, I've been searching for a fix to an annoying lag when I right click and this led me to Indexing Options. I was thinking that if Windows is having to index all your pics/vids, it may be slowing down the search. I could be wrong but what have you got to lose? It won't harm anything else if you try and you can always rebuild the Index if it fails. I remember stopping the indexing service on earlier Windows OS and this speeded things up no end!

Type 'in' in the Start search box and it will give you the link to Indexing Options. Click the Advanced button then click File Types tab. Scroll down the file types until you come to .jpg, (or any other file type that's causing you problems) then uncheck box and click OK. Also, you could try this instead/as well. Instead of clicking Advanced, click Modify. Then click the little triangle next to C:, in the drop down list, Users will probably be ticked. Click the little triangle again and find your personal folders, probably ticked. If you are storing all your pics in 'My Pictures', uncheck the box and click OK. This will stop Windows indexing this folder. When you go back to the Indexing Options window, the number of indexed locations will be less and My Pictures will be included in the Exclude list. There's all sorts of options you could try here, perhaps one will work?

Another idea is changing the processor resources to speed up background services.
Control Panel then System then click Advanced System Settings. In the System Properties window that opens, the Advanced tab will be displayed. Click the Performance, settings button, then in the Performance Options window, click the Advanced tab. Then in Processor Scheduling enable Background Services instead of Programs.

If any of this works you owe me a pint!

Solved this problem by removing photo programs

What worked for me was going to Remove Programs and uninstalling all of the old programs I wasn't using -- especially programs associated with image file types, like graphic design programs and picture organizers. After re-booting, all is well.
