Clearer

Clearer is a simple application developed to remove all history files left behind by Delphi after completing projects in this programming language.
It offers support for .dsk, .bak, .tmp, .pdb, .identcache and .local-formatted files, giving you the possibility to add new ones to be taken into account.

Simple interface and settings

It's wrapped in a basic interface made from a minimalistic window, where you can review the supported file types, remove any of them from the task, as well as add new ones by typing extensions into the dedicated field.
After opening a BDS project or folder with the Delphi project files, you can view the containing items autodetected by the program, namely the full path of each file, as well as pick the ones you want to delete while keeping the remaining ones safe.
Moreover, you can ask the tool to clear AppData too. The entire task shouldn't take long, depending on the total size of the items, after which you can open the Delphi directory to inspect results.

No installation required, besides .NET Framework

There is no setup pack involved, which makes Clearer portable. You can drop the downloaded files in a preferred directory on the disk or copy them to a USB flash drive to directly launch it on any PC without previous setup.
It doesn't add new entries to the system registry or create files on the HDD without asking for permission. However, it needs .NET Framework, since it was built with the aid of this platform.

Evaluation and conclusion

The software application had minimal impact on the computer's performance in our tests. Tasks were carried out fast and Delphi remnants were successfully removed from the disk.
On the other hand, it froze several times when we attempted to open project files, probably because Clearer hasn't been updated for a long time and has compatibility issues with newer Windows.
