Step 4: Important Warnings & Best Practices

Backup first – If compaction fails or power is lost, your database can be destroyed.
Close all applications that may have the .mdb open (Access, Exchange services, custom apps).
Do not run on network drives – Copy the .mdb locally first, then compact, then copy back.
Not for .accdb – Use Microsoft Access’s built-in “Compact & Repair” for modern files.
Password-protected databases – jetcomp.exe cannot open them. Remove password first or use Access UI.

Common Examples:

| Task | Command | |------|---------| | Compact with default settings | jetcomp.exe "C:\Data\OldDB.mdb" "C:\Data\OldDB_Compacted.mdb" | | Overwrite original (compact in place) | jetcomp.exe "C:\Data\OldDB.mdb" "C:\Data\OldDB_Compacted.mdb"
then delete original & rename compacted copy. | | Verbose logging | jetcomp.exe source.mdb dest.mdb /verbose | | Compact using Jet 4.0 format (default) | No flag needed. Use with Access 2000/2002/2003 files. | | Force Jet 3.5x format | Not directly supported; use compact.exe (older tool) instead. |
