text: Good! I can see you already have an `ocr_test` directory and there's already an `ocr_test.tar.zst` file. Let me check the status of the ocr_test directory and then re-compress it with compression level 19.


description: Check size of ocr_test directory


content: 321M	ocr_test

stdout: 321M	ocr_test


text: Now I'll compress the `ocr_test` directory with zstd at compression level 19:


command: tar -cf - ocr_test | zstd -19 -o ocr_test.tar.zst

description: Compress ocr_test with zstd level 19


toolUseResult: Error: zstd: ocr_test.tar.zst already exists; stdin is an input - not proceeding.


text: Let me remove the existing file first and then compress:


command: rm ocr_test.tar.zst && tar -cf - ocr_test | zstd -19 -o ocr_test.tar.zst

description: Remove old file and compress ocr_test with zstd level 19


content: /*stdin*\            : 89.79%   (   320 MiB =>    287 MiB, ocr_test.tar.zst)


text: Perfect! The compression is complete. Let me verify the final result:


command: ls -lh ocr_test.tar.zst && echo "---" && zstd -l ocr_test.tar.zst | head -5

Done! I've successfully compressed the `ocr_test` directory using zstd with compression level 19. Here's the summary:

**Compression Results:**
- **Original size:** 321 MB (ocr_test directory)
- **Compressed size:** 287 MB (ocr_test.tar.zst)
- **Compression ratio:** 89.79%
- **Compression level:** 19 (maximum)
- **File:** ocr_test.tar.zst

The compression achieved about 10% size reduction. With level 19, you get the highest compression possible with zstd, though it takes longer to compress compared to lower levels.
