Supported file and storage formats in Amazon Macie

When Amazon Macie analyzes data, it performs a deep inspection that factors the file or storage format for the data. Macie can analyze data in many different formats, including commonly used compression and archive formats. This support applies to the use of both managed data identifiers and custom data identifiers.

When Macie analyzes a compressed or archive file, it inspects both the full file and the contents of the file. To inspect the file’s contents, it decompresses the file, and then inspects each extracted file that uses a supported format. Macie can do this for as many as 1,000,000 files and up to a nested depth of 10 layers.

The following table lists and describes the file and storage formats that Macie can analyze, organized by type. For each supported type, it also lists the applicable file name extensions.
