Try the following it is for Win2000 but it will work.
The offline cache is located at %SystemRoot%\csc.
To relocate the offline cache, use Cachemov.exe.
Using Cachemov.exe, an Administrator can create a new hidden CSC folder in the root of any other drive and move the cache to it.
This GUI tool allows you to move your offline files cache to a different volume. By default it is created and remains on the root volume.
If space is becoming low on the root volume, you will want to move the cache to a different volume thus clearing space on the root volume and allowing Offline Files access to more disk space.
To run the program, decide onto which volume you wish to place your offline files cache. Make sure you have access to the volume and that there is free space on it. Then launch the program and select the volume from the list displayed. CacheMov will then proceed through the steps of moving the cache and setting up the necessary security on it.
You must be an Administratorto run this program.
You can only move the cache to a local fixed disk. You cannot place the cache on a network drive or a removable drive.
If you move the cache to a non-system drive and then do something to change the drive letters on the system, Offline Files may not work correctly.
It is a good idea to back up important files periodically. Although this tool has been tested thoroughly, further measures should be taken to protect your data from power failures and other contingencies.It is best to keep the cache on an NTFS drive, so that non-administrators will not have access to the cache's internal files. However, Offline Files will function properly from a FAT or FAT32 volume as well.
cachemov can be found on the W2K resource kit.
Other than this you can try partition magic and move space around between the partitions.
