# Limits > Every number that bounds what June does for you, in one place: files, projects, organizations, sharing, memory, schedules, the sandbox, voice and more. Source: https://www.dearjune.ai/docs/limits Use these limits to check whether a file, chat or scheduled job fits. Each row links to the behavior and recovery options. A limit on what a page lists does not necessarily limit what you can keep: the memory and project lists below show only a recent selection. Your ChatGPT or Claude plan has separate usage windows, shown in the composer’s meter; see [Use your own plan](/docs/models/your-plan). Splitting a file or a job does not restore exhausted plan usage. ## Chat and files | What | Limit | | :-------------------------------------------------------------------------------------- | :------------------------------------------ | | [Files in one message](/docs/chat#attach-files) | 5 files | | [Size of one file](/docs/chat#attach-files) | 20 MB | | [Paste turned into a file](/docs/chat#attach-files) | 32 KB and up | | [Text read from text and CSV files](/docs/chat/files#what-june-reads-from-each-file) | 200,000 characters per message | | [Text read from a workbook or a deck](/docs/chat/files#what-june-reads-from-each-file) | 20,000 characters per file;
