This highly depends on the performance of your hard disk, your PC, the number of files and folders and the settings. Just use our free an fully functional trial version and try for yourself. TreeSize scan using parallel threads and you won 't find a disk space manager that scans faster.

When using the new sqlite-based index file format, this is possible. Simple export such an index file, and use it for comparison at a lter time. 

We also offer another disk space manager called SpaceObServer which is made for continuous reporting and saves its information on file level, so it can be used to observe the size growth of individual files. It stores its analyzed data in an SQL database.

SpaceObServer uses less RAM than TreeSize and the reporting is faster and more flexible. It also offers advanced scripting capabilities through OLE Automation. If you are interested, please visit: https://www.jam-software.com/spaceobserver/.

This kind of task is more suitable to our hard disk manager SpaceObServer. By continuously collecting directory information in a database, SpaceObServer enables your to get instant information about directory sizes, growth of allocated disc space (for each subdirectory) and to define filters (E.g.: Files created within the last X days) that can be applied immediately on the shown directory branch.What you could do in TreeSize is to take a look at the "Age of Files" graphics (look for files create within the last few days), or compare the current scan with a former stored XML report ("File > Compare With XML Report").

Yes,TreeSize will handle files with a full path longer than 255characters correctly. The integrated TreeSize File Search also offers a possibility to search all files with a full path longer than 255 characters.

If you want to get a combined report, then please add the command line switch /GROUPSCANS true to the beginning of the command line.

If you want seperate reports for those drives, please split it up into separate TreeSize calls.

Unless instructed otherwise, TreeSize deletes files using the same mechanism as the Windows Explorer. That means, if according to your settings files get deleted to the recycle bin, they can be recovered from there.

In case you permanently deleted a file and want to recover it, please try using a recovery software.

Yes. When using the "Move Checked" feature of the file search, there is an option that allows you to decide whether or not the directory sturcture will be preserved.

Since we do not know which files you have on your disk and also do not know which files you, your colleagues or family members might be interested to keep, we cannot give you any concrete advice here, unfortunately.

In general, some files are needed by certain applications and should not be deleted because otherwise those applications might not work as expected anymore. Fortunately, those files are usually located in a directory with the name of such a program. It is also not recommended to delete files of the operation system that are located in C:\Windows.

The results of the TreeSize Temporary File Search and the Browser Cache Files are quite safe to delete. If you delete files and are unsure, only delete the files in question to the recycle bin or move them to a different path from where you can recover them again a few days after you deleted them.

The "Move Files" feature of the TreeSize File Search and the TreeSize "Details" list makes this easy.

Let the first user export his history through "History > Manage history data > Export to file". The second user then can import this file through  "History > Manage history data > Import from file", the data will get merged.
