MX (.mx)
- Import and Export fully support Wolfram Language MX files.
- Wolfram Language MX files can be created with DumpSave and read with Get.
Background & Context
-
- Wolfram Language serialized package format.
- Used for the distribution of Wolfram Language packages.
- Stores arbitrary Wolfram Language expressions in a serialized format optimized for fast loading.
- Binary file format.
- MX files cannot be exchanged between operating systems that differ in $SystemWordLength.
- MX files created by newer versions of the Wolfram System may not be usable by older versions.
- Developed by Wolfram Research.
Import & Export
- Import["file.mx"] reads in an MX file and returns an expression.
- Export["file.mx",expr] serializes an arbitrary Wolfram Language expression and saves it as an MX file.
- Import["file.mx",elem] imports the specified element from an MX file.
- The import format can be specified with Import["file","MX"] or Import["file",{"MX",elem,…}].
- Import["file.mx"] is equivalent to Get["file.mx"].
- See the following reference pages for full general information:
-
Import, Export import from or export to a file CloudImport, CloudExport import from or export to a cloud object ImportString, ExportString import from or export to a string ImportByteArray, ExportByteArray import from or export to a byte array
Import Elements
- General Import elements:
-
"Elements" list of elements and options available in this file "Summary" summary of the file "Rules" list of rules for all available elements - Import elements:
-
"Expression" reads and evaluates all expressions, returning the last one "HeldExpression" list of unevaluated expressions "ExprStruct" returns the result as an "ExprStruct" data structure - Import by default uses the "Expression" element for Wolfram Language MX files.
