The files with the TGZ format are basically the .TAR archive files that are compressed using the GNU ZIP File compression program. While a user comprises of a large volume of files that they prefer compiling into one file, they can make use of the TAR file format in this regard. On the other hand, the .TAR format does not really compress the files that it acquires in its file archive.
To compress the .TAR format files, the user is required to make use of the file compression utility. While the Gnu Zip file compression application is used in this regard, the compressed TAR file is then saved with the TGZ format. This is helpful in bringing down the size of the file, which saves disk space and makes the file easier to download and distribute.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .TGZ file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .TGZ file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .TGZ file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
