I have a file with *.ext extensions. How to open that file in ubuntu? I search on this, they say that it can open with norton commander in windows.
Update: The file is zipped sqlite database
finally i found the answer. thanks for @bodhi.zazen for the command. when I run file thefile.ext it is detect as Zip archive data, at least v2.0 to extract . And I unzip it. then, I found the file name xxx.dat. so i do the same command file xxx.dat. and the result is SQLite 3.x database. And I browse the database by sqlitebrowser on ubuntu. thank you for your help
