## 7.3. Automatic Extraction of Data on Upload

EKM will automatically extract metadata from a file when it is uploaded to a repository, updated using send changes, or created/synchronized if it is a remote file.

Data extraction is supported for the following file types:

- `Ansoft Designer File` (.adsn)

- `ANSYS Electronics Desktop File` (.aedt)

- `ANSYS Electronics Desktop Archive File` (.aedtz)

- `CFX Definition` (.def)

- `CFX Result` (.res)

- `Fluent Case` (.cas)

- `Fluent HDF` (.cas.h5)

- `HFSS File` (.hfss)

- `Icepak Data` (.ice.xml)

- `Icepak Packed Project File` (.tzr)

- `Maxwell File` (.mxwl)

- `Mechanical APDL Database` (.db, .cdb)

- `Mechanical APDL Input` (.dat, .inp)

- `Mechanical APDL Output` (.out)

- `Mechanical APDL Results` (.rst, .rstp, .rmg, .rfl, .rth)

- `Polyflow Data` (.dat)

- `Simplorer File` (.asmp)

- `Workbench (or AIM) Project Archive File` (.wbpz)

- `Workbench Simulation/Mechanical Database` (.dsdb, .mechdb, .mechdat)

If the file type you are uploading is a custom object type or extension to a built-in type that has a custom metadata extractor application defined for it, then in addition to the built-in metadata that are extracted, custom properties that are specified will also be extracted. You can display these custom properties using (More) > Display > Properties. See Defining Type Attributes for a Custom Type in the Administration Guide to learn more about specifying a custom metadata extractor program for a custom type.

If the custom metadata extractor replaces (not extends) the built-in metadata extractor then it must extract all built-in as well as custom properties.

While metadata is being extracted, you may see a warning icon next to files in the file list window, and the message Data extraction is pending if you hover over the icon. You can monitor the progress of data extraction on the Data/Extraction Monitor page.

Note:

- While data extraction is in progress, an EKM User License will remain checked out for you until the extraction is complete, even if you sign out of the EKM web client.

- While data is being extracted from an archive file, data will be synchronously extracted from the CAE files that it contains. Synchronous extraction also occurs when data extraction from a CAE file results in the creation of a new file for which an extractor has been defined. For example, if you upload a *.cas file and that file type has been configured to extract CAX files, a VCollab *.cax file will be extracted from the *.cas file and added as a child of the *.cas file. Data will be extracted from the *.cax file in the current data extraction thread.

- Packed Icepak projects (.tzr files) do not include solution data.

- If metadata extraction fails, refer to Metadata extraction: “Extracted data is not set” in the EKM Troubleshooting Guide.
