Save file compatibility

Does a xlsc save file created for a 32 bit exe version also works for the same 64 bit exe version and vice versa?

Also wonder if an xlsc file works on another computer?
For example if the exe file and save file are located on a shared network where multiple users can access it.

The XLSC file is just a secure copy of the workbook (it’s basically your original XLS file). So yes, 32-bit and 64-bit EXE files can share the XLSC file, they work on other computers and can be shared. Of course, only your EXE can open the corresponding XLSC files.
