Unable to allocate enough memory

[Thane5]

I was trying to compress the game files of Witcher 3 into a 7z archive, but after a few seconds NanaZip would show an error about being unable to allocate enough memory for this operation.

• The uncompressed files are about 33GB
• i have 32GB of RAM
• I tried to do the same with the latest release of 7-zip, which did not have the issue. While compressing the files 7-zip only needed just above 1,8GB of RAM.
• Tested using Windows store preview version on Windows 11.

Can you provide the screenshots of "add to archive" options dialog and error dialog?

@Thane5

Got it.

But which the compression level you have chosen? For example, I wonder to see the screenshot like that.

I didn't change any settings, so i guess this should be the ones it uses:

@Thane5

Got it. I will try to reproduce it.

Got the same issue 16GB of RAM Issue comes when you try to compress a big enough file (a 38GB file in my issue) and ONLY with the right click, "add to filename.7z". The other options work fine. RAM is filled up completely and then the compression crashes.

Same here. It happens only sometimes when I try to create an archive via the context menu without opening the extended archive creation dialog. When I use the dialog, it works perfectly fine. It't not even a big bunch of files, just a folder with mp3s, 270 MB.
