Import/Export Tables/Databases in .gz format about heidisql

+1 on this feature request. The current support for ZIP export is nice but to complete the cycle a way to import zip archives would be a great improvement. Gzip is not a container as ZIP is so it should be much easier to implement I think. At least it is really easy in Java, hopefully in Delphi as well.

No, ZIP is easier to implement in Delphi, as there is a native wrapper for that, even with large file support. Perhaps because ZIP is more spread in the Windows world, and Delphi's tradition is also Windows. Saving GZ files requires some 3rd party library.

I can live fine with ZIP import! :)

Everything I find for Delphi is a GZ decompressor which does everything in memory, which may be ok for small files, but not for large database backups.

To my surprise I just found my Windows 11 has a tar.exe available on the command line. Unfortunately, this version seems not to be able to decompress my gzipped .sql file:

PS C:\backups> tar -xvzf database.sql.gz
tar.exe: Error opening archive: Unrecognized archive format

Same error with bsdtar.
So I tend to think using a separate 7-zip installed by the user may be a good idea.

I mean this could be a dependance... the option is deactivated, if you try to activate it, it should try to search for 7-zip. If not installed msgbox or such thing.
