What Is a DO File?
A file with the .DOfile extensioncould be a Java servlet file.
It’s used by Java web servers to deliver web-based Java applications.

Other DO files are most likely Stata batch analysis files.
These are usually calleddo-filesand areplain text filesthat contain a list ofcommandsthat are to be executed together in a series.
Similar to Stata files is the ModelSim macro file format that uses this same file extension.
Those kinds of files store macro-related commands used with Libero SoC.
It’s also a loop command used withbatch files.
Stata Batch Analysis files only work within the context of a computer that’s runningStata.
For example,do myfile.
There’s more information availablefrom Stata’s websiteabout do-files if you need help.
ModelSim DO files are used with Mentor GraphicsModelSim, which is included in theLibero SoCprogram suite.
These are also plain text files that can be viewed and edited with any text editor program.
Apple II disk images can be used withCiderPress.
Instead, just rename .DO to .PDF so that your PDF reader will recognize the file.
