PreCacher: PreCaching for Drives
Posted: Thu Sep 11, 2025 10:01 pm
This is an app that reads all files under 64? KB in size as a means of pulling them into the Windows Disk Cache to speed up all the files ALL drives are slowest at reading.
According to the author, Scott D Bowen (for Windows 7? 2013):
70% of all files in total, in a Windows install are smaller than 64KB
All those files fit into around 1GB of DRAM..!
The result:
- Using Samsung 830 SSD (128GB) on Intel Core i5 system with encryption.
- Total Small Files PreCached: 76,838
- Total File Content Cached: 882,922,403
Initial pre-cache time: 124.5574 seconds
Subsequent read-back: 13.02602 seconds

Combined with Primocache a couple of runs of this app would mean that ALL small, slow to read files would be cached in you L2 and/or L1 cache..!
With space to spare!
ie: This app will make is so that PrimoCache is (small, slow) File Aware..!
The reason I post this now is that I have just found a copy of this, thought to be lost app, buried in an old backup of mine!
I have moved on to Linux (CachyOS) with it's many free caching options and way less bloat/spyware BS, so wont be testing this.
But, like MS Compact:

tested here:

I expect it to be VERY helpful...!?
