SUMMARY
Hi,
I often have to handle large files (over 1GB but sometimes even less) in .zip format to which I add other files, unzip some or modify text files inside.
I usually do this on a Windows partition in NTFS format and I often get corrupted or outdated files (despite the notification of the operation) with the creation of new large files with strange names and without suffix that I believe are temporary karc files.
Also, when unzipping a file from an archive to a folder, karc has the habit of overwriting a file with the same name without asking for any permission.
Strangely enough, this only happens on very large .zip files because in all other cases it works perfectly.
I hope you can solve these problems that have persisted for a long time as Krusader and karc are essential for me and the entire community.
In the meantime, I thank you and wish you a good day.

STEPS TO REPRODUCE
1.  Create a very large .zip file with different types of files such as smaller .zips and text files in a Windows NTFS partition.
2.  Add files to the above or edit text files inside.
3.  Unzip some files from the above archive to a folder with files with the same name.

OBSERVED RESULT
Corrupted files, not updated (despite the notification of the operation) and creation of new raw files.

EXPECTED RESULT
Obviously working as expected.
