Opening GP4 Files without CCITT Group 4 File, Guitar Pro Ver. 4 Tablature, or GTX Group IV Format /CALS Picture Software Installed
Different software packages tend to sometimes share similar file types. CCITT Group 4 File, Guitar Pro Ver. 4 Tablature, and GTX Group IV Format /CALS Picture are some of the popular programs that use the GP4 file extension, so you should be able to use any of these three to open your file. You might even be able to find others by doing a quick Google search.
A word of warning, though. Be sure to scan any free software you download with a malware checker before running it on your computer.
If You Have CCITT Group 4 File, Guitar Pro Ver. 4 Tablature, or GTX Group IV Format /CALS Picture Installed
If one of these software packages are already installed on your PC, but it still won't work to open your GP4 file, you might have to check that the file associations are correct. Right-click on the file, select "Open With...", and then select CCITT Group 4 File, Guitar Pro Ver. 4 Tablature, or GTX Group IV Format /CALS Picture. That will create an association between the GP4 file extension and your chosen software.
Your GP4 Might Be Corrupt
Finally, if you're still having issues opening your GP4 file, download the file again or ask the sender to resend it. It's possible that your GP4 file might be corrupt. As a last resort, contact the software developers to see if they may be of further assistance.
Here's a list of GP4-related software programs and their developers:
| Software | Developer |
|---|---|
| CCITT Group 4 File | Windows Programmer |
| Guitar Pro Ver. 4 Tablature | Arobas Music |
| GTX Group IV Format /CALS Picture | PC Software Company |
