When I look at properties of a mapped drive, I see that all of the available space is used. the properties box says that the mapped drive has 1 gb capacity and the .99 gb are used and available space is 52 Kb. This creates a problem that programs won't open like quickbooks that needs to write to the disk. Other xp machines in my office show the opposite space allocation. .99 gb free, and 52 kb used. this happens on all mapped drives on this xp machine. this computer was fat32, I converted it to ntfs. this didn't solve the problem. the question is what controls this information and how do I free up the space. the folder that I'm mapping has way more that 1 gb. so this information has to do with the client computers. the orginal folder is on a 2003 server. this problem just occurred over night.
