Renaming a file changes its identifier within the file system, but the underlying data typically remains unchanged. Errors occur when other software components, system processes, or users rely on the original name. This dependency could involve open file handles held by running programs, configuration files referencing the old name, scheduled tasks, scripts, or symbolic links pointing to that specific filename. File permissions associated exclusively with the original name might also cause access issues after a rename.

Common scenarios involve automated processes breaking. For instance, a cron job script configured to process "daily_report.csv" will fail if the file is renamed to "report_daily.csv" without updating the script. Content Management Systems (CMS) managing website assets or development projects using build tools can encounter broken links or failed compilation if referenced filenames are modified without corresponding code changes.

The main advantage of renaming is improved organization. Key limitations include breaking dependencies and potential confusion. Mitigation involves updating references first, using unique identifiers instead of names where possible, or employing refactoring tools in development. Modern systems and cloud storage often mitigate this by using internal unique IDs for access, making visible names less critical for functionality.
