User Temp Files
Temporary working directories under %LocalAppData%/Temp on Windows and $TMPDIR on macOS and Linux collect short-lived data created by installers, updaters, browsers, office suites, media tools, and developer utilities while they run. These locations often fill with extracted installer payloads, crash dumps, log files, partial downloads, decompressed archives, lock files, named-pipe endpoints, and application scratch data that should disappear automatically but often remains after crashes or interrupted cleanup. Kudu removes leftover user temp files that are no longer in active use, without touching personal documents, accounts, saved settings, or passwords.
Why clean User Temp Files?
- Abandoned installer extraction folders and MSP or PKG staging files accumulate after failed updates, and you notice temp storage growing by gigabytes even though the app already installed
- Stale lock files and orphaned temp markers from a crashed app can make the next launch report that another instance is already running or that a temporary file cannot be created
- Partial downloads and half-written archives left in the temp directory can cause repeated repair loops, checksum errors, or installers that stop at the same percentage every time
- Programs that rely on writable scratch space fail when the temp area is crowded, showing errors like not enough disk space, cannot write temporary file, or export and print jobs that never finish
- Old crash dumps, debug logs, and render scratch files can consume SSD space silently, and the symptom is a system drive that keeps shrinking without obvious large files in Documents or Downloads
- Corrupted temporary conversion output from editors, PDF tools, or media apps can be reused by mistake after a crash, leading to blank previews, failed transcodes, or documents that reopen with missing generated assets
- SQLite databases stored in temp locations by some apps can become page-fragmented after heavy churn; VACUUM rewrites the file to compact pages without deleting rows, but leftover temp database copies and WAL or journal files still waste space and may trigger slow startup or long cleanup pauses
