Basic Examples  (2)

Save a computed value to the InterPlanetary File System (IPFS):

Wolfram Language code: ExternalStoragePut[Range[10]]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

Save a computed value to Dropbox:

Wolfram Language code: ExternalStoragePut[RandomColor[7], ExternalStorageBase -> "Dropbox"]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

Scope  (2)

Default Path  (1)

Save an expression to Dropbox using the default target path:

Wolfram Language code: ExternalStoragePut[ListPlot[RandomInteger[10, 20], Filling -> Axis], ExternalStorageBase -> "Dropbox"]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

Path Specification  (1)

Save an expression to Dropbox. If the target directory does not exist, it will be created:

Wolfram Language code: ExternalStoragePut[RandomWord[10], "/NonExistentFolderX77/SomeRandomWords", ExternalStorageBase -> "Dropbox"]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

Options  (3)

ExternalStorageBase  (2)

Dropbox  (1)

Save an expression to Dropbox specifying the target path:

Wolfram Language code: ExternalStoragePut[Plot[Sin[x], {x, 0, 3Pi}], "/NonExistentFolderX77/SinPlot", ExternalStorageBase -> "Dropbox"]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

IPFS  (1)

Save an expression to the InterPlanetary File System (IPFS). IPFS does not require a target path because files in that system are identified by a content identifier (CID) that is automatically generated:

Wolfram Language code: ExternalStoragePut[Entity["City", {"Lima", "Lima", "Peru"}][EntityProperty["City", "Population"]], ExternalStorageBase -> "IPFS"]

Retrieve the value:

Wolfram Language code: ExternalStorageGet[%]

OverwriteTarget  (1)

By default, ExternalStoragePut does not overwrite a file if an existing path is provided and the expression to be saved is the same as the one in the existing file.

Save a expression to Dropbox:

Wolfram Language code: expr1 = Graphics3D[{Pink, Icosahedron[]}]
Wolfram Language code: ExternalStoragePut[expr1, "NonExistentFolderX77/icosahedron", ExternalStorageBase -> "Dropbox"]
Wolfram Language code: %["Path"]

Save a different expression to the same path:

Wolfram Language code: expr2 = Graphics3D[{Cyan, Icosahedron[]}]
Wolfram Language code: ExternalStoragePut[expr2, "NonExistentFolderX77/icosahedron", ExternalStorageBase -> "Dropbox"]

A new file will be created:

Wolfram Language code: %["Path"]

By setting the OverwriteTarget option to True, the target file will be replaced:

Wolfram Language code: ExternalStoragePut[expr2, "NonExistentFolderX77/icosahedron", ExternalStorageBase -> "Dropbox", OverwriteTarget -> True]
Wolfram Language code: %["Path"]
