Hello,  
I just upgraded to 0.7 on my way to 1.0 and noticed that I couldn’t install the JLD package.

```julia
julia> Pkg.add("JLD")
WARNING: Base.Pkg is deprecated, run `using Pkg` instead

```

I was able to install the JLD2 package, but with that I was not able to load some old data that I had saved in jld format.

```julia
using JLD2
@load("very/important/data.jld")
ERROR: LoadError: ArgumentError: only JLD2 files are presently supported

```

Is there a way I can either open jld files with JLD2 or convert jld files to jld2 files? This data is kind of important.  
Thanks,  
Philip

I think the easiest way will be to download julia v0.6.4 from [https://julialang.org/downloads/](https://julialang.org/downloads/)  
and use `JLD.jl` to load the file and then save it with `JLD2.jl`.

That may be somewhat tedious but if you have lots of files, you can probably write a small script to automate that.  
i.e.

```julia
cd("very/important/")
for file in readdir()
     if endswith(file, ".jld")
         data = load(file)
         save(file*"2", data)
    end
end

```
