All three Studio 3T editions support GridFS, the method MongoDB uses to store files larger than the document size limit of 16 MB. Try it today.
MongoDB and GridFS
GridFS is the file abstraction method MongoDB uses to store and retrieve files larger than 16 MB.
GridFS divides large files into equal chunks with a default size of 255 kB and stores them as a separate document. The last chunk, however, can be as large as necessary.
MongoDB creates two collections to store the files. The first collection –
chunks – contains the file chunks; the second –
files – contains the file metadata. When you search GridDS for a file, the driver will reassemble the chunks as needed.
GridFS is a fitting mechanism to store files in MongoDB, which complements the schema-less (hence faster) retrieval of information provided by the document model.
Because files are divided into smaller chunks, it’s easier to access specific sections of a file, sparing the memory-expensive task of loading an entire file.

- Click OK.
Drop a GridFS bucket
- Right-click on the bucket to be deleted.
- Choose Drop Bucket.
Open GridFS view
Right-click – Right-click on the target GridFS bucket and choose Open GridFS view.
Shortcut – Choose the bucket to view and press Enter
Add a new file
Right-click – Right-click anywhere within the GridFS view and choose Add Files.
Button – Click on the green + sign in the toolbar.

View the GridFS collections
Each GridFS bucket creates two corresponding collections: BucketName.chunks and BucketName.files.
BucketName.chunks contains the actual file chunks:
While BucketName.files contains the file metadata like filename, uploadDate, and contentType:
