Unfortunately I still see severe delays when viewing certain folders.
The problem is also independent of enabling or disabling the various handlers of PDF-XChange:
For example, it takes several seconds for the folder shown below to be listed, every time it is displayed. Other folders with fewer or even many more items on the other hand appear without delay in a fraction of a second.
If such folders with delayed display are moved or copied somewhere else, then sometimes the delay disappears completely.
It is also not due to the enabled folder size calculation, since many folders appear instantaneously, which also have numerous subfolders of various sizes.
These are the only shell extensions I still have enabled at all:
Please let me know what else could be the reason for this issue.
