EmEditor has won over 24 International awards, including the Shareware Industry Award in the Best Apps category. It has also earned Windows 10 certification from Microsoft.

EmEditor is available in both 64-bit and 32-bit builds. As you can see from the examples on right, the 64-bit build runs as much as 16% to 74% faster than the 32-bit build when dealing with very large files. If you use 64-bit Windows, the 64-bit build of EmEditor is absolutely recommended!
