Background Compression

If you are copying a lot of files to a compressed path, the background 
compression system will tend to lag behind.  That is, ZipStream will have 
many outstanding compression tasks not yet completed.  There is no problem 
with this, as this is the way ZipStream is designed to operate.  You may 
look at files and see that they are not compressed yet.  This is quite 
normal, as the compression operation needs time to catch back up.  We 
highly recommend that you use the ZipStream Monitor  program so that you 
can be aware of the background operations taking place. 

Note:  You can use the files immediately even thought they are still 
queued for compression. 

When the background compression operation gets well behind, it will 
attempt to rectify this situation by boosting its own priority slightly. 
 This means that you may notice a small drop in system performance as 
ZipStream tries to catch up. 

If you need the outstanding compression operations to complete in the 
shortest possible time, you can use the ZipStream Sync  utility to provide 
a significant boost to the background compression priority.
