Help with TC 8.51a-32 bit and copy large directory problem

[GALLASTRONIX]

Dear Programmer, for first, many congratulations for your very good TotalCommander, for me is the best file manager in the world.

In the last v8.51a - 32 bit I have encountered an big problem with copy file command from/to HD to USB key and from HD to HD.

I have copied one directory of Jdownloader v2.0, with many file and many subdirectory, and the TotalCommander v8.51a go to crash and closed (with no popup indication of error).

Simple closed.

TC have copied only una side of total directory and files from my original directory.

I have zipped my directory of Jdownloader v2.0 (about 73 Mb) and I'm disposed to send to support of Totalcommander for testing the last version with this stranger bug (in the previus versions is all OK).

I have tested this problem in my PC desktop with WindowsXP - Sp3, in an PC Desktop external with WindowsXP- SP3 and in an other portable PC with Windows8, the result is the same, when I copy this directory, with many file and many subdirectory, TotalCommander close, with none popup of indication error .
Simple closed.

Please is possible send to support of TC, my directory incriminated, via WeTransfer service?

It's an big problem for me and it's very stranger for TotalCommander v8.51a - 32 bit.

Many thanks for your interest to my problem.

Dear Christian, on your response I have tested again TC v8.51a and I
have discovered the arcane problem.

I have tested TC in an other PC without my Kaspersky Internet Security
antivirus and.... TC v8.51a WORKING ALL OK.

The arcane is: KASPERSKY antivirus.

I have tested again TC in all my PC with Kaspersky ad the problem is
present.

In the identical PC's, without Kaspersky Internet Security, TC WORKING
ALL OK !!

I not have an responce for this stranger discovery, but this version
of TC have the problem with Kaspersky antivirus.

Dear Christian you have any suggestion for resolve my problem?

Bye for now.

Yes, unfortunately only Kaspersky labs can help you in this case. I'm using standard Windows function CopyFileEx to copy files, that should be handled also by Kaspersky.
