WSAEDQUOT - 10069 (0x2755)

Ran out of disk quota.

Updated: Feb 21, 2026

Technical Background

The error code WSAEDQUOT with the numeric value 10069 and hexadecimal representation 0x2755 is returned by Windows Sockets API when an operation fails due to insufficient disk quota. This indicates that the system has exhausted its allocated storage space, preventing further data from being written or transferred.

Error Details

The error WSAEDQUOT is specific to file and directory operations within a networked environment where disk quotas are enforced. It typically occurs when an application attempts to write data to a file or directory that has exceeded its allocated quota on the server or local storage system.

Common Causes

  • Exceeding the configured disk quota for the user or group performing the operation.
  • Insufficient free space available on the storage device where the operation is attempted.
  • Incorrect usage of network resources, leading to unexpected data transfers that consume more than allocated quotas.

Real-World Context

This error can occur in various scenarios such as file uploads, large-scale data transfers, or when multiple users are simultaneously accessing shared resources. It is particularly relevant in environments where disk quotas are used for resource management and security purposes.

Is This Error Critical?

The criticality of this error depends on the context. If a user's quota is exceeded, it can lead to denial of service for that user or group. For system administrators, it may indicate potential issues with storage management or network resource allocation.

How to Diagnose

To diagnose WSAEDQUOT errors, follow these steps:

  1. Review Operation Context: Check the environment and context in which the operation was attempted. Ensure that the correct file or directory is being accessed.
  2. Validate Parameters: Verify that all parameters passed to the API are valid and within expected limits. Pay special attention to file paths and sizes.
  3. Confirm Object Types: Ensure that the object types (files, directories) match the intended operation. Incorrect object types can lead to quota-related errors.
  4. Verify Input Data: Confirm that the input data does not exceed the allowed size or quota limits.
  5. Check Limits or Constraints: Review any system-wide or application-specific quotas and ensure they are configured correctly.

How to Resolve

To resolve WSAEDQUOT errors, consider these practical steps:

  1. Correct Parameter Usage: Ensure that all parameters used in the operation are correct and within valid ranges.
  2. Adjust Operation Context: If possible, adjust the context of the operation to avoid exceeding quota limits. This might involve reducing file sizes or splitting large operations into smaller chunks.
  3. Restore Data: In cases where data corruption is suspected, restore from backups if available.
  4. Retry Operation with Valid Inputs: Attempt the operation again with valid inputs and ensure that all constraints are met.

Developer Notes

Developers should be aware of disk quota limitations when designing applications that interact with networked storage systems. Implementing checks for available space before initiating large data transfers can help prevent WSAEDQUOT errors.

Related Errors

  • Error WSAENOSPC: Indicates no space left on device, which is a similar condition but not quota-specific.
  • Error WSAEACCES: May occur if the user does not have sufficient permissions to access the resource.

FAQ

Q: What causes WSAEDQUOT errors?

A: These errors typically occur when an operation exceeds the disk quota allocated for a user or group. They can also be caused by insufficient free space on the storage device.

Q: How do I prevent WSAEDQUOT errors?

A: Regularly monitor and manage disk quotas to ensure they are not exceeded. Implement checks in your application to verify available space before initiating large data transfers.

Summary

The error code WSAEDQUOT (10069) is a specific resource limit error that occurs when an operation fails due to running out of disk quota. Understanding the context and causes can help in diagnosing and resolving these issues effectively.
