Error Code 0x800700c1 Summary
The error code 0x800700c1, also known as ERROR_INVALID_NAME or NS_E_BADFILENAME, generally indicates that an invalid file name was encountered during a system operation. This can be quite broad and occurs across various scenarios related to file management within Windows operating systems. Common causes include attempting to create, access, modify, or delete files with names that do not conform to the naming conventions supported by Windows. These rules are strict about what characters can and cannot be used in file names, such as avoiding certain reserved characters like <, >, :, “, /, \, |, ?, * and ensuring no more than 260 characters are used for a full path name. Additionally, special considerations apply to long paths that exceed the maximum limit Windows allows without enabling “Long Path Support”. This error can also surface when there’s an issue with network drives or remote shares, possibly due to permissions issues, incorrect server configurations, or network connectivity problems affecting file operations.
Description of Error Code 0x800700c1 and Common Scenarios Where It Appears
This error can occur in several places where file system access is involved. One common scenario is during software installation processes, especially if the installer attempts to place files into directories that are too deep (i.e., exceed the MAX_PATH limit of 260 characters) or contain special characters not supported by Windows. Another frequent occurrence is when attempting to rename a folder through user interface elements like drag-and-drop operations in Explorer, leading to a dialog indicating an invalid file name error when the new proposed name fails validation rules. It can also happen during manual attempts to modify registry keys or values associated with specific file paths, particularly if these entries are malformed according to Windows conventions. Additionally, network issues such as unavailable servers, incorrect mappings of network drives, insufficient user permissions on remote shares, or misconfigurations in group policies restricting certain actions like renaming files over the network can trigger this error when trying to perform operations across a networked environment.
Howto solve error code 0x800700c1
1. Ensure you are using valid file names by avoiding special characters such as <, >, :, “, /, \, |, ?, * and spaces at the beginning or end of names.
2. If dealing with long path issues (paths exceeding 260 characters), enable Long Path support in Windows 10 through registry modifications. To do this:
– Open Registry Editor by typing “regedit” into the Start menu search bar and pressing Enter.
– Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
– Create or modify a DWORD value named ‘LongPathsEnabled’ with a value of 1 (enabling long path support).
3. Check network configurations, including verifying that your network drives are correctly mapped and accessible from the user account performing the operation. Ensure you have proper permissions on remote shares.
4. For issues related to software installations failing due to invalid file paths, try running the installer in compatibility mode or with administrative privileges if not already done so.
5. If you encounter this error while renaming files through Explorer, attempt to rename using command line tools like ‘ren’ instead, which might bypass interface limitations.
