#2465 — Re: Get["file.mx"] doesn't work

To add to what Albert writes, somewhat surprisingly to me the .mx format also depends on the storage medium. That is, when using the same machine (i.e., control therefore on OS and 32/64-bit), I have made .mx files and stored that to my local hard drive. I then copy those files over to a network drive, which I believe is Linux but appears to me just as a mapped network drive within Windows. The .mx files then no longer work. I have to re-run and generate the .mx files directly to the network drive.

mx, as the documentation says, is a machine and version dependent
format, it depends e.g. on OS and also differs for e.g. 32 vs. 64 bit
machines. It also does differ between various versions of mathematica. I
think your best bet is to find a machine with the same OS and Processor
type as your old machine running the same Mathematica version as your
old computer and convert to something machine independent, e.g. wdx.
Maybe in the future you also want to use machine independent formats,
although they are a little less efficient. Of course it could also be
that your files got corrupted, your old computer might have written
nonsense to disk before completley breaking down...

hth,
