I have two computers NOT CONNECTED through internet or LAN. Therefore, I can't use standard synchronizing software, since it usually requires to have both computers available in the same time. I need to synchronize some 80 GB so I can't just simple copy all files to a USB flash disk or DVD and synchronize with them. I don't have an external harddisk and I don't want to buy one.

I am looking for a software which would worked similarly to this:

1. make "a snapshot" of a folder and its subfolders and files at a computer 1

2. take the snapshot to a computer 2 and make a compare

3. in results I would see differences

4. according to results I could tell the software to: a) delete files which were removed at the computer 1, b) decide which way should be copied changed files, c) copy new files. All the new or changed files would be copied to a specified folder. Then, I could copy the folder to flash disk or DVD.

5. I would take the flash disk or the DVD with files and with actualized snapshot to the computer 1 and I would use the software to synchronize again.

I found one software called Advanced Flash Synchronizer (http://www.urltoy.com/afs.htm) with similar functionality, but it enables to compare by timestamp and filesize only. I would prefer more comprehensive check of changed files, maybe by CRC or MD5 check.

Does anyone know about a software like that?

Thanks a lot for your help.
