no this issue is only when double clicking

but i am getting a 1-2 sec delay during right click #16440

Do you know if this is related to the file size, or is it the file type (in which case it's the same as #16286)?

it seems to be related to file size
just now opened a 3gb rar file through 7zip(default for rar/zip) and it was not resonding for 5-10sec

small files are opening fine
just opened a 20mb video file working fine

[yaira2]

What about from File Explorer?

What about from File Explorer?

opening fine without any issue both video/zip in 1-2sec

[yaira2]

I'm considering whether this might be an issue with the Process.Start API, which could explain why File Explorer doesn't encounter this problem. It's likely that 7zip is using the same method as Files. While I'm hesitant to draw a definitive conclusion, I wanted to share this theory in case anyone else has encountered it before.

@BedBug2479 do you have a third-party antivirus application on your device?

@BedBug2479 do you have a third-party antivirus application on your device?

there is McAffee that comes free for 1year with the new lapy

[yaira2]

Can you check if this issue applies when turning off McAffee? It's possible that it scans files when opened from a third-party process such as Files and can potentially cause a slowdown depending on the size.

Can you take a look at "Control Panel > Security and Maintenance > Reliability Monitor" and see anything about Files.
