I'm wondering if the issue is actually with PACK. The way PACK works is it copies non-deleted rows from kwik.dbf to a temp table, deletes the original kwik.dbf, and then renames the temp table to kwik.dbf.

Windows 7 introduced many security restrictions compared to XP, especially if you have data tables in so-called "protected" folders. Maybe a security restriction is preventing one or more of the actions required for PACK to succeed.

You might want to look at Doug Hennig's whitepaper re: VFP and Windows Vista: http://www.stonefield.com/pub/vista.zip . It's for Vista, but Win7's security restrictions are very similar to Vista. Look at the Security and Protected Folders sections.

If this was a one-time, not repeatable occurrence, a couple more ideas:

- are there many leftover temp files in your VFP temp files folder?
- is your antivirus program set to not real-time scan VFP data and temp files folders?
