Sharing Files/Folders

Clarifications

It's difficult to be accurate in your particular case.

But if the OS is Windows 7, you can simply right click to find out.

depends on how its shared. it is all about the same but this is the basics. log onto the box where the folder resided and rt click. the click sharing and security. click on the sharing tab and that is a list all all who access and what access they have.

if the share was setup without accessing the advanced settings then it's read only;

the easiest tests are:
a> access the share from another system on the network and try to create a new file of folder in it; if you get access denied then the share is read only
b> to check files simply open a file and without changing it try to save it; if you get access denied the share is read only;

Setting up the advanced permissions on a share can mean one user or group has full control and others can still be blocked out at read only and yet others can be completely blocked out with no access at all.

More information would help get better answers. Are you sharing from your computer (local) or are you accessing files on another computer (remote). Version is important too.

If you are sharing from your XP machine, right click on the folder you want to share. Select properties and then go to the sharing tab. There is a button that says "Permissions" on it. That one will give you the information you need and allow you to change it.

What is format of the file? What kind of software?
