Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |
Use this file for
- Checking email size handling
- Testing container and package pipelines
- Testing archive extraction on servers
Testing notes for TAR
- There is no index, so listing the contents means reading the whole archive.
- Like ZIP, tar entries can contain absolute paths or "../", and can be symbolic links. Validate before extracting.

- What is inside the 100 KB TAR file?
- A ustar archive with a README and payload.bin, 99,840 pseudo-random bytes, followed by the two zero blocks that end every tar archive.
- Why is there no 1 KB TAR sample?
- A tar archive is built from 512-byte blocks and ends with two empty blocks, so the smallest archive containing a README and a payload is larger than 1 KB.
