        "content": "Yes \u2014 there *are* some freeware (or open-source) tools that help you automatically build a folder or disc compilation so that its contents *fit precisely* within a specified capacity (like a CD-ROM, memory card, etc). Some tools simply show you how much space you've selected, others try to *optimize* which files go onto each disc/folder. Here are several solutions, ranging from fully yours-automated tools to tools that only assist you with capacity info, plus tips on how you might combo them to get your desired result.\n\n---\n\n## \u2705 Tools that help with capacity-aware file selection or disc building\n\n| Tool | Platform / Free? | What it offers relevant to your goal |\n|---|---|---|\n| **SizeMe** | Windows freeware | Designed to **split a large collection** of files into *disc-sized* sets. SizeMe lets you define your target media size (e.g. a 700 MB CD) and then divides the files/folders into the minimum number of discs/folders needed so nothing overflows. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Disc_spanning?utm_source=openai)) |\n| **Open Burning Suite** | Open-source, cross-platform (Windows, Linux, macOS) | When building a data disc, its wizard shows the **capacity usage** and warns if the total of the files/folders exceeds the disc capacity. Useful for seeing precisely when you're about to overflow. ([openburningsuite.pages.dev](https://openburningsuite.pages.dev/data-wizard?utm_source=openai)) |\n| **AnyBurn (Free edition)** | Windows freeware | Lets you assemble file(s)/folder(s) to burn onto CD/DVD/BD and shows when you've exceeded capacity. While it doesn\u2019t auto-select which files to drop or include, it gives you feedback so you can adjust. ([free-codecs.com](https://www.free-codecs.com/download/free_any_burn.htm?utm_source=openai)) |\n\n---\n\n## \u26a0\ufe0f Tools that might *partially* help (or help you plan)\n\nThese won\u2019t automatically pick the \u201cbest\u201d set of files to maximize space, but they make manual planning easier.\n\n- **Folder Size / WizTree / WinDirStat**: These tools show individual file sizes and folder sizes graphically. You can use them to see the biggest files and adjust what to include or omit. Useful for deciding which files you may need to leave out so total stays under the limit. ([techspot.com](https://www.techspot.com/downloads/6654-folder-size.html?utm_source=openai))  \n- **FutureBurn**: A modern open-source disc burning tool (Windows 11 etc.). You build the folder/ISO then burn; the interface gives feedback on disc capacity. Does not auto-optimize file selection, but transparent about capacity. ([ithub.global.ssl.fastly.net](https://ithub.global.ssl.fastly.net/sp00nznet/futureburn?utm_source=openai))\n\n---\n\n## \ud83c\udf10 How they differ / what an ideal tool might need\n\nTo fully meet what you're asking (\"you don't need to calculate how many small files to fill that particular space\"), the tool should:\n\n1. **Allow setting a size limit** (e.g. 700 MB) for the target (CD or s-card).\n2. **Select files automatically** (or suggest a maximal set) so that the set of files is as close as possible to that limit without exceeding it.\n3. Optionally **optimize** which files to include so you use space efficiently (like packing algorithms).\n\nMost free tools either help with (1) + (feedback) or (1)+(2) but work manually. Tools like SizeMe appear more automatic.\n\n---\n\n## \ud83d\udd0d Practical suggestion / workaround\n\nIf you want an easy workflow:\n\n1. Use a tool like **Folder Size** or **WizTree** to list all your files, sort by size.\n2. Decide what your target capacity is (for a CD, it might be 700 MB; memory cards depend on size).\n3. Either:\n   - Use **SizeMe** to split everything into folders/discs sized appropriately.  \n   - Or manually drag files into your disc-burning compilation using something like AnyBurn or Open Burning Suite \u2014 these tools show how much capacity you\u2019ve used so far, so you can watch the progress and stop before overflow.\n\n---\n\nIf you want, I can track down *specific tools* that do exactly \u201cauto-select files to completely fill exactly X MB/GB\u201d (like knapsack problem solvers for file sets), possibly open-source, for your OS (Windows / Mac / Linux). Do you want me to pull those up?"
