Virus left some damaged folders and files. Explorer cannot see, except highest level folder or file, and shows windos that says "....path\filename is not acessible. Access is denied". Explorer cannot see any lower folders/files in tree structure.

Freeware Unlock program is able to browse tree structure, fixes folders and files if you move them one at a time, restoring attributes or whatever is damaged.

How can I fix the whole tree structure quickly? I have hundreds, and one by one is a killer. Thx.

Does Microsoft Excel 4.0 work on XP?

Does XL 4.0 (competitive) Upgrade check for something installed on your PC before it will install?

Can you tell from outside the package if XL 4.0 upgrade is 4.0c (for example, if it has 3.5" disks?)

How do you start the utility to layout the dialog boxes in XL 4.0? Do any other versions have this utility?

Thanks for any knowledgeable responses!
