Windows 10: Ctrl-A in File Explorer is very slow. "Copy as path" also slow.

Selecting all the items in a folder in File Explorer is slower than any previous version of Windows I've worked with. And by slower I mean really slow.You can test it by going into a folder containing a good amount of items like C:\Windows\WinSxS. Do a Ctrl-A and wait. Then you can do a "Copy as path" on the selection and again, wait. On my old laptop the waiting time is horrible. On my desktop i7-9700k it's not as bad but much slower than what I was used too on Windows 10 where Ctrl-A is instantaneous. To be fair about "Copy as path", it was still slow on Windows 10 but I programmed my own

Windows 10 file explorer very slow (working on it...) issue

This seemed to help. Time will tell. It certainly is more helpful and practical than the suggestion to end toe Explorer task and start a new one.

 

Extremely slow Windows Explorer. Please help.


Hello - there's solution posted here - but cannot say if it works totally yet though but it has helped me just now. Hope it helps you too. Save any work open first, before you do this.

Taken from site at this board - Solved File explorer slow with loading thumnails and files - Windows 10 Forums

Step by step guide:
1. Hold Win+r to open run
2. Type msconfig and hit ok or enter
3. Click Services
4. Navigate to Windows search (you can sort the list in descending alphabetical order)
5. Uncheck tickbox
6. Click apply then ok
7. Select to restart now

Hope this works for you.

-- Your system will need a restart when it reconfigures itself so save any work first. I tried this myself and it ran slow first time while it indexed slow directories - then after I closed file explorer and reloaded it it ran fast on slow directories. I hope it helps you. Best of luck and best wishes.

 

Windows explorer copy and file browsing running slow.

A few months ago windows 10 explorer.exe was running slow when browsing folders and copying files within the C drive. I have a solid state drive and copying files from one location on drive C to another location on drive C would transfer around 20KByte/sec, but only within explorer. If I used another file manager such as 7-zip, copying and browsing files would be extremely fast. I used the Windows 10 "Reset the PC" and the problem went away for a few months and explorer was running fast. Now a few months later the problem is back. If I profile explorer.exe (using the profiler called Very Sleepy) during a copy operation of a folder from drive C to drive C, one of the explorer.exe threads is running at 100%. Within that thread, 90% is the function "GetVolumeNameForVolumeMountPointW", and 10% is the function "DeviceIoControl". This was the case before and after the reset of the PC. I've tried many suggestions such as disabling indexing, disabling antivirus, and disabling Carbonite, but no luck.
