TL;DR: ChatGPT can now process ZIP files up to 512MB, supports nested archives, and enables batch processing of multiple files. This guide covers everything from basic upload to advanced API integration.
Latest Updates for ZIP File Handling
ChatGPT’s file handling capabilities have evolved significantly in 2024. Here are the key improvements:
- Nested Archive Support: Process ZIP files containing other compressed archives, ideal for complex project structures
- Enhanced Size Limit: Increased to 512MB per file, allowing for larger datasets and code repositories
- Batch Processing: Handle multiple files simultaneously with intelligent queuing system
Understanding File Processing Capabilities
ChatGPT’s file processing system works in three stages: upload, analysis, and processing. Here’s what happens at each stage:
1. Upload Stage
During upload, the system:
- Verifies file integrity and scans for malware
- Checks file size and format compatibility
- Prepares the file for processing in a secure sandbox environment
2. Analysis Stage
The system then:
- Determines file structure and content types
- Identifies nested archives and dependencies
- Plans optimal processing strategy
3. Processing Stage
Finally, ChatGPT:
- Executes requested operations in parallel where possible
- Maintains data integrity throughout processing
- Provides real-time progress updates
Technical Implementation
Basic File Upload
// Initialize the ChatGPT file handler
const chatGPT = new ChatGPTAPI({
apiKey: process.env.CHATGPT_API_KEY
});
// Configure upload parameters
const uploadConfig = {
maxSize: 512 * 1024 * 1024, // 512MB in bytes
allowedFormats: ['zip', 'rar', '7z'],
retryAttempts: 3
};
// Example upload implementation
async function uploadFile(fileBuffer) {
try {
const response = await chatgpt.files.upload({
file: fileBuffer,
purpose: "file-analysis",
config: uploadConfig
});
return response;
} catch (error) {
console.error('Upload failed:', error.message);
// Implement retry logic here
}
}
This code demonstrates a basic file upload implementation with error handling and retry logic. The uploadConfig object defines key parameters like maximum file size and supported formats.
Troubleshooting Guide
Common Error Scenarios and Solutions
1. Size Limit Exceeded
Error: File size exceeds maximum limit of 512MB Root Cause: Attempting to upload file larger than 512MB Solution: 1. Use file compression to reduce size 2. Split large files into smaller chunks 3. Remove unnecessary files from archive
2. Format Compatibility
Error: Unsupported archive format Root Cause: Using non-standard compression format Solution: 1. Convert to supported format (ZIP, RAR, 7Z) 2. Ensure archive is not corrupted 3. Check for password protection
