TDLCACHE reads as 256MB free on a disk with 19GB Free #57

Many larger games seem to have this bottleneck, like ones packed with ISOs.

This is on a Dosbian/RPi 4 system, IE Dosbox, on a USB disk with plenty of free space formatted exFAT.

I have tried using a different folder for TDLCACHE, as well as deleting more files to clear up space with no change. I have also unzipped them in Windows and manually put them in TDLCACHE. There is plenty of space, TDL simply can only see 256MB available.

Am I right in assuming that this is a hard limit on launching at 256MB in size?

Actually, it's a dosbox limit. When I'm in dosbox, if I type DIR, I only see 256MB free no matter how much space is actually free. If you figure out a way to fix how dosbox reports free space, let me know and I can add it to the documentation.

I'll leave this issue here as a feature request to have TDL provide an option to ignore the amount of free disk space available.

Thank you for pointing this out.

It looks like this is actually fairly easy to do and is listed in the DOSBox readme. I found it from a Vogons post and I'll quote it here for people looking for a workaround.

You simple have to mount the drive with the option " -freesize [size]"

For example, "mount C C:\dosgames -freesize 250" would make it have 250MB of free space.

So basically do this, but change it to whatever the max is that DOSBox allows.

[solved] How to change amount of reported free disk space?

updating my config file with the following line is what got the launcher to launch the larger games:

mount C C:\dosgames -freesize 1024

I tried 4096 first, but either I goofed it up in a way I didn't see or DOSBox does not like the larger size. Regardless I can confirm that I did launch larger games with this setting.

Excellent, thanks for confirming. I've added documentation to the README that explains what you found. I'll leave this issue open as a feature request for "don't check if there is enough free space in the cache".

I've decided that this isn't really a TDL issue, as it's the environment reporting the incorrect space, so I'll close it for now. If there's a use case where disabling the free space check makes sense, we can re-open this.
