🧹 Free Windows disk scanner — finds what fills the drive, lists every file it deletes Osenpa Disk Analyzer 1.1.1 · Windows 10 2004+ / 11 · x64 · free · one 155 MB file ![the cleanup log it prints](https://onehack.st/uploads/default/original/3X/7/a/7a67c25c3061bce3c4322bafcb7cef1b5034e801.png) **How I run it** 1. I take the portable EXE, which asks for admin, or the Store build, which does not — they reach different folders. 2. I pick one drive, or **Scan all** , and it reads the NTFS index first, then crawls what it cannot index. 3. I work the filters: **Large & old** (1 GiB, 90 days), **Videos** , **Games** , **Archives** , **Safely cleanable**. 4. I clear cache and temp with **Free space now** , and my Downloads folder stays mine. 5. I look at what it removed before I press delete: freed space, every file, every skipped item, by name. **What it says about itself** - No treemap, no duplicate finder, no registry play — printed on the product page. - Delete is permanent, so the printed list is the record you keep. - Search shows the first 2,000 matches and keeps the real total beside it. - Everything runs on your machine; the launch only checks its update file. **The goods** — [product page](https://osenpa.com/osenpa-disk-analyzer) · [portable EXE 1.1.1](https://osenpa.com/downloads) [what it sends over the network](https://osenpa.com/network-and-data) 155 MB is .NET 8 riding inside, so nothing else to install. Softpedia scored it 3.5/5; Uptodown counts 61 downloads — you are in the first room.
