Yes. Open the TreeSize Professional File search using the Windows Start menu or the TreeSize Tools menu, activate only the duplicate file search, add the network paths in the "Scan paths" panel and start the scan.
The Windows Explorer and the TreeSize drive list do show the space that is physically allocated on the drive while TreeSize shows the space that is occupied by all files under a certain path. Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space.
Another possibility is that not all parts of the drive could be scanned due to access restrictions. Therefore it is highly recommended to run TreeSize as administrator. If you want to get notified if a folder cannot be scanned, please open the options dialog (File > Options) and enable "Show error messages during scan" under the option page "Scan > General". Turning on the Option "Track NTFS specific features" in the Options dialog may result in more accurate results, because it racks e.g. hardlinks, but slows down scans. If a drive letter points to a sub-folder of a network drive, the allocated space (correctly) reported by TreeSize may also be much smaller than the physically allocated space on this drive reported by the Windows Explorer because possibly the whole drive is not accessible through the network. Beyond the space that is needed for storing the files itself, additional space is used for storing management data like the File Allocation Table of the file system or the boot sector. It is not possible to free this space with TreeSize or any other tool. This is usually 0.5 - 2% of the occupied space.
Another possibility is that you are using a Software RAID - like Windows offers it - which spreads the data with redundancy over several disks. These disks will appear as one logical volume and the failure of a single disk will not cause any data loss. But for storing the redundant information additional space is needed, which cannot be used for user data. A special characteristics of Offline Files can lead to wrong values for the allocated space of stub files. To avoid this, either ensure that the user which runs the scans has full read access to the scanned file system.
You can simply install the full version over the trial version.
No. TreeSize does not actively change the archive bit, and the system only changes the archive bit if a file is written. TreeSize works strictly read-only when scanning and searching and also does not modify the last access date if possible,
You can reach the Help of Treesize through the "Help" menu and can open a PDF user 's manual in the windows start menu. If you are particularly interested in scheduled scans, please take a look at the chapter "Schedule TreeSize Tasks".
A "TreeSize Professional - Site License" covers all installations of TreeSize Professional at one location of your company.
By default, the exports done through „File > Export“ contain only folder and subfolders. To include also the files, click the "Customize" button In the Save-dialog and click "Include single files in export" and also "Export the full directory branch" if applicable. You will find these options also at: "Tools > Options > Export".
Using "File > Export > Copy List of Files" you can easily copy a list of files to the clipboard. This function is also included in the context menu of the TreeSize directory tree.
Since TreeSize holds file information of scanned directory structures in your system RAM, the theoretically maxiumum disk size that can be scanned or searched by TreeSize is only imitated by your systems memory.
The 32 bit edition of TreeSize can use a maximum of 2 GB RAM (default for Windows applications). This is sufficient for most Home or Small Business environments.
For larger file system structures with several million of files, we recommend the native TreeSize 64 bit edition which is available in TreeSize Professional.
