video folder with special custom columns opens slow

[edymaegi]

xyplorer is normally fast.
However have more than 600 mp4 files and added there the custom columns frame rate and length.
With these added columns xyplorer opens the folder very slow and to delete a single video file (even if short) takes more than 7 seconds. Is there a way to speed this up?

From the help file:

General Remarks on Custom Columns
You pay a price for this feature: Retrieving and processing all this extra information takes time. The
shell as used here is v-e-r-y slow compared to XYplorer's native functions, so browsing a list with
Custom Columns using shell properties will be notably slower than browsing a list without such
columns. Also running a script for each item in a list and for each column of type "Script" takes a lot of
time.
You can escape the processing of Custom Columns by pressing ESC. The cells where data retrieval
was skipped will then show "[Skipped by ESC]". Can be useful when browsing large folders with
complex Custom Columns on a slow machine.

Also set your custom column trigger to List, or On Click, not Browse.

And the scripts for these custom columns are...?
