Memory reclamation speed in SoftPerfect RAM Disk

现在在使用SoftPerfect-RAM-DISK　总体体验很不错。但有一个我使用过程中发现的“问题”，不知道能够在软件更新中改善一些：
因为之前使用另一款RAMDISK软件，各个方面都不错，有了使用体验的对比，感觉“SoftPerfect-RAM-DISK”在建立的内存盘删除文件后，回收内容比较慢……不知道这一点是否可以改善一些。当然在“SoftPerfect-RAM-File System”中已经做得非常好，回收内容很及时。

只是提一个小建立。希望你们的软件越来越好用！

I'm currently using SoftPerfect RAM Disk and the overall experience is very good. There is one "issue" I've run into though, and I wonder whether it could be improved in a future update.

I used a different RAM disk product before, which was good in every respect, so I have something to compare against, and it feels like with SoftPerfect RAM Disk the space is reclaimed rather slowly after files are deleted from the RAM disk. I wonder whether this could be improved a little. In SoftPerfect RAM File System it's already done very well, the memory is released promptly.

Just a small suggestion. I hope your software keeps getting better!

Good news: in RAM Disk version 26.7 we shortened the reclaim delay considerably. Memory freed by deleting files now comes back within about 10 to 15 seconds on NTFS, where previously it took around 70 seconds. On exFAT it takes a little longer, roughly half a minute, because Windows does not report deleted blocks through TRIM on an exFAT volume, so the driver scans the allocation bitmap itself and confirms a block is really free before releasing it.

That is also why RAM File System feels instant in comparison: it is a real file system driver rather than a virtual disk, so it knows a file is gone the moment you delete it, and hands the memory back the same second. No TRIM, nothing to wait for.

If you are already on v26.7 or later and still see a long delay, check that your disk uses dynamic allocation with Automatically release memory (TRIM) ticked. A fixed size disk holds its full allocation for as long as it exists, so nothing is ever returned.
