There is no need to reinstall TreeSize Free in order to change the setting for the Windows Explorer's context menu.
On the 'Options' tab, you can simply change the option at runtime.
Since Windows Vista and later, Microsoft enforces more strict security rules on the operating system. One side effect of this is that you may not see your mapped network drives anymore (Windows 8 and later), or they all appear disconnected (typically in Windows Vista and 7) in all applications that run with administrator privileges.
This is because Windows uses different user environments for non-elevated and elevated processes. There are some workarounds to gain access to those network drives anyway:
Yes, TreeSize Free may be used in commercial and enterprise environments. TreeSize Free has the limitation that it cannot scan network drives in Windows domains, this is only possible with the Professional edition.
However, please consider purchasing a few licenses of TreeSize Professional to support the further development of all editions.
Differences to the size shown in Windows Explorer can occur because the free version does not take all NTFS-specific features into account.
Features like Alternate Data Streams (ADS), Deduplication (Windows Server 2012 and above) or recognition of hardlinks are not evaluated in TreeSize Free. The personal and professional edition come with an option to explicitly analyze these extended NTFS features, which may make the results more accurate.
Starting TreeSize Free "as administrator" will show larger parts of the disk that cannot be accessed by "normal" users.
Assuming that your OneDrive files are synchronized locally, you can use TreeSize Free to both analyze how much space is used up on the storage and locally.
First, select the OneDrive folder under "Home" -> "Select Directory" -> "Documents and Cloud" -> "OneDrive" or by using the directory icon above and navigating to the OneDrive folder that way.
TreeSize Free then scans the OneDrive storage. The "Allocated" column tells you how much space these files take on your local drive while the "Size" column represents the size of these files on the storage.
Unfortunately it was necessary to create a separate project in the Microsoft Store for the latest version of TreeSize Free.
The version in the legacy project is only a dummy version of TreeSize Free, which does not provide any functionality anymore, is not updated and only serves as a reference to the new version.
If you want to continue using TreeSize Free and get all updates, please uninstall the old version and switch to the new version here.
Please excuse the inconvenience.
Unfortunately, the previously used UPX compression no longer works under 64-bit. Therefore, the executable file in the 64-bit version is significantly larger than that of the 32-bit version.
One way to fix this is to enable NTFS formatting for the file or to use Windows' own compression (available from Windows 10).
The reason why PDF files cannot be opened is because Adobe Acrobate Reader is preventing to open files from an application with administrator rights via its Protected Mode. To solve this issue disable protected mode by doing the following:
