If you delete data or objects in an Access database, or if you delete an object in an Access project, an Access database or an Access project can cause fragmentation and reduce the efficiency of disk space usage. Compressing an Access database or an Access project actually copies the file and organizes how the file is stored on disk. Compression also optimizes the performance of Access databases and Access projects.
So we think of compressing it when we're too slow to tolerate an ASP program that's growing in the database. But the usual way to download him to the local and then use MSAccess to complete the compression operation, and then upload!
Note: This program is actually through the FSO permissions and the Jet engine connection, so before using, please confirm your server support FSO (FileSystemObject) permissions and install the latest driver of access! From a safe start, please back up the original database before compacting! The running environment that has been tested through:
WIN98SE+PWS, win2000+iis5.0
The following is my collation of the source code, copy saved as Compact.asp and uploaded to the database directory can be used normally.
