    Lag/Delay in Explorer when Renaming Copying Creating Files


    I have been noticing randomly delay or lag in my Windows Explorer whenever I do operations such as create new folder or files, copy/paste files, or rename files.

    By lag, what I mean is that lets say I rename a file from "File A" to File B", I don't see the change in the file name instantaneously. It takes few seconds I have to press F5 to refresh the window to actually see the changes.


    I am running on Windows 8.1

    I joined the forum to bring up the same complaint.

    I 'upgraded' last week, from Win 7 HP sp1(different laptop) and from win 8 to 8.1 (this laptop via Windows Store).

    Superfetch and indexing are not turned off. Accessing files in various devices seem to take forever compared to win 7.

    Yesterday, I spent some time using the file explorer to rename and organize files on an external hard drive. Soon enough, the system came grinding to a slow crawl. Bringing up task manager took 'forever'. Eventually, it showed the explorer utilizing over 2GB of memory (6GB total in system). After closing the explorer window, the memory was not released. I had to restart explorer.exe to release the memory. Once I replicated the event, I began to wonder if this is unique to my machine or inherent in the OS.

    I generally use XNView as my file manager. But, it wasn't performing as well as it should, or as well as it had been with Win 7. That's why I tried to bypass the middle man in XNView.

    With Win 7, the external devices spin down after time has passed. There would always be lag while the accessed device spin up. With Win 8.1, the spin down seemed to be next to no time passing. I spend 5 to 10 seconds being careful in what I'm doing with the files, I have to deal with the lag before the action takes effect.

    In summary, there is the explorer 'memory leak?' and the quick spin down of external devices, both affecting the performance of the file explorer.

    Any way to fix this issue?

    I searched microsoft.com and came up with these two links:

    Windows 8.1 Explorer.exe Memory Leak! - Microsoft Community

    Windows8.1 explorer.exe memory leak when used with 'sort by - Microsoft Community

    The first one turned out to be pertinent (maybe). I mentioned XNView earlier, and the program introduced a context menu handler .dll several iterations ago. I never put the file explorer.exe through its paces until last week, with Win 8.1.

    Once I used CCleaner to disable that .dll, I put the explorer through some file management activities and the memory it uses hardly budged.

    I included the second link in case there is a file organization issue at play. I try to keep my folder names closest to root as short as possible.

    That didn't really help me. I am still having the issue. I believe your problem and my problem are two different issues.

    The symtom you've described might be due to some incompatible 3rd party software installed in your PC. To isolate the problem, let's try:
    1. Win+R->msconfig then click on the "services" tab, put a check mark on "Hide all non Microsoft services" and click on "Disable all"
    2. Open task manager, go to "Startup" tab, for each item, right click and disable.
    3. Reboot your PC and try to see if the problem goes away. If it does then go back and re-enable one by one until you encounter the same problem.

    I tried all the steps and it didn't seem to fix the problem. However, one note is that I didn't disable my antivirus (ESET Nod32).
