But I replace tc7z64.dll with newer versions of 7z.dll (renamed to tc7z64.dll) when update TC I lost the change.Use internal 7-Zip - Packer
Use the 7-Zip packer built directly into Total Commander, based on 7-Zip sources. You can replace tc7z.dll/tc7z64.dll with newer versions of 7z.dll
And if I use symlink overwrite the original when update.
