Hello,

Currently, when Bandizip decompresses tar.gz and tar.zst, it only extracts the tar file instead of directly decompressing the tar file.

This confuses me a bit: gzip and zstd are supposed to support stream decompression. For example Rufus supports writing tar.gz directly to a USB device.

I don't know much about zstd. But I know Caddy and curl support zstd, since it's used for internet browsing, it should support stream decompression.

So can Bandizip support stream decompression tar.gz and tar.zst?

Best regards,

Yes. you are right.


TGZ is a steamable format, but Bandizip does not support it.


In most cases, the extraction sequence is as follows.

1) An user opens a TGZ  file.

2) Bandizip extracts the file to memory and reads the content of the file. - 1

3) User select files to extract

4) Extraction. - 2


If you want to extract a TGZ file and you don't need to check the list of the file, the sequence could be done at once like this.

1) Extract the file to memory ->  Read Contents -> Write it to HDD 

But, Bandizip does not support it (because it's not that easy.)



Best Regards, 
Park, KH
