    I have this bug where it is slow to delete files or folder in the finder, around 5-10 seconds or so. I have tried to delete finder.plist, relaunching finder, reset smc and pram to no avail, even using first aid in disk utility. Anyone to be of help? Is this related to caches? Thanks a lot! Here is a video clip of the problem:

    I have experienced this multiple times, from early El Capitan beta to the most current one. I guess this is a known issue for El Capitan.

    Are you still experiencing it now? Thanks for the reply, Not so sure though on how to fix it or if the upcoming release will fix it. Submitted an Apple Feedback regarding this issue and awaiting response.

    Slow deletion only happens when I delete over 500 files, recently. For single, small one, it is ok.

    Interestingly to say, Windows can delete even over 8000 files in one minute or less.

    Is it slow when you start up in safe mode and don't have all your startup items loaded?

    Things that might cause this would include:

    • A Time Machine backup in progress
    • Spotlight indexing occurring
    • Hard drive is near capacity
    • Background network activity
    • Something hogging CPU that shouldn't be

    But it seems not to be any of the above.

    You could test a new user account account to see if the problem exists there.

    I've had wonky Finder issues through the years and it seems a reinstall has always cleared them up for me (after wasting a lot of time trying to find a simple fix). You could reinstall EC over what you have now and see if that clears it up.

    Yeah I have this bug for a month or two now and it's exasperating! One clue: I found a posting that said to delete finder prefs etc and restart the finder and it worked the first time I tried it! It was just like old times with files deleting instantly and moving to other folders weightlessly just like they alway have. But then I put my prefs back and the bug was back and now I can't get rid of it no matter how many times I delete the prefs following the same instructions etc. So weird. So annoying. Help

    Beginning with Mavericks, Finder prefs have been cached by the system and simply deleting the plist file doesn't necessarily/usually change the cache. The cache changes the plist file back after a restart.

    El Capitan has introduced further System security so any searches you do on the web about how to delete finder prefs should be narrowed to El Capitan. What worked on Yosemite or prior systems may not work in El Capitan.

    Additionally, there are system files other than plists that may be corrupted (such as .sfl) so research carefully.

    Wow cool! Where's the cache! I'll delete that too! It's pretty weird how everything is totally fine except it takes 20 seconds to delete or move a file.

    Try double clicking on one of those files you've just deleted.
    Chances are nothing will happen, because the Finder has already deleted it, and is just taking its sweet time showing that action on your screen.
    Finder actions have been handled asynchronously since half of forever ago. That can make things slow, or at least appear slow, when the system has other, more important things to do.

    ANSWER
    • Open System Preferences > Accessibility > Mouse and TrackPad
    • Adjust the Double-click speed to something faster.

    Thank you, otribin! You have solved an annoying issue I had to put up with for years! [Even after writing to Apple developers long ago, several times!]
