Troubles Opening PAR2 Files

QuickPar Isn't There

When you double-click your PAR2 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have QuickPar for %%os%% installed. The typical path of opening your PAR2 with a double-click won't work because %%os%% cannot make the program connection.

Tip: When another PAR2 application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Obsolete Version of QuickPar

Sometimes your installed version of QuickPar won't support your Parchive 2 Index File file. Download the latest QuickPar version from the Open Source website to ensure you have the correct one installed. This issue mainly occurs when your Parchive 2 Index File file was created by a newer version of QuickPar than you have on your PC.

Tip: Find clues on the correct software version by right-clicking your PAR2 file and clicking "Properties".

Ultimately, most of the difficulties opening PAR2 files are due to having the wrong version of QuickPar installed.
