Re: [Ql-Users] Maximum size of a file
Hi, > Sorry for my english, i badly explained myself ... No, it was I who misunderstood! Theoretically, there are limits, in practice, you'll be more limited by the disk size limitation itself than the directory size. Wolfgang ___ QL-Users Mailing List
Re: [Ql-Users] Maximum size of a file
Regarding the internals of a QXL.WIN disk, I documented that at http://qdosmsq.dunbar-it.co.uk/doku.php?id=qdosmsq:fs:qlwa there's a table at the end with host file sizes and the resulting internal block size.

I wanted to understand if there are limits to creating files within a .win file The directory entry contains a file_length field, it is a 32 bit longword. This allows for files to be up to 2^^32 -1 bytes in size, in theory. It all depends if the internals of SMSQ etc deal in signed or unsigned numbers. 2^^32 - is big! 4,096 Mb or 4 Gb.

Re: [Ql-Users] Maximum size of a file
Hi, I have used a 1GiB file w/o problems. I may be wrong, but I dimly remember somebody telling me they use a 2 GiB long QXL.Win container. The fact to be aware of is that these containers can always, at the most, deals with 65536 clusters, as the number of clusters (called groups in SMSQE speak) occupies a word. That means that, for a 2GB "disk", each cluster would occupy 64 sectors = 32KiB. Seems quite a waste in view of the generally limited size of QL files... HTH Wolfgang ___ QL-Users Mailing List
