zip file Download Ti99Dir version 6.2a now

Ti99Dir is a Windows program to browse through TI-99/4A files (v9t9 format), Archive files (v9t9 format and created with Barry Boones archiver), .DSK files (v9t9 and PC99*) or .IMG files (HFDC, SCSI or IDE) on a PC. From version 4.2a it is also possible to view monocolor and multicolor TI-Artist files and to view GIF files with an external viewer (like Irfanview).

This version of Ti99Dir is build on Windows XP and should still run on Windows 95/98/ME/NT/2000 (Not tested by myself) and Windows 7 and 8.1.

New features:

1) Browsing SCS, IDE, CF7A+ and DSK images on volume information block (VIB), directory descriptor record (DDR), file descriptor index record (FDIR) and file descriptor record (FDR) level. This demonstrates the inner layout of the storage media. See menu option Tools -> Show image VIB, DDR, FDIR, FDR.

2) Reading and writing compact flash cards (like Cf7a+ or IDE cards) can now also be used in Windows 98. To speed things up you better use an USB 2.0 port for this!

3) Extracting files from one or more selected ARC-files and/or DSK-images to a directory with the same TI-name as the original ARC-file or DSK-image.

4) Converting one or more ARC-file to DSK-image with the same TI-name as the original ARC-file.
