Thank you Atarigeezer for the good program.
I only was able to partially test the program (mainly, Scan Atari Files option).
Testing : Search folders (ANALOG folder in Pooldisk_Too_CD1)
If "Start Search" button is pressed again after completion of the search, only ATR File details are displayed. "Location", "File Name", "Sectors" and "Bytes info" are lost (blanck)
Also, when pressing "Start Search" button again, the ATR counter at the top of the left corner of the Search result windows changes from (052/0796) 89_SEP.ATR which is the result of the first button pressing and becomes (105/1606) 89_SEP.ATR. The more the button is pressed the higher the number will go.
The counter give 052 as the number of ATR images. But the actual numbers are 053 ATR images in ANALOG subdirectory. Similarly, the search returns 10 ATR images in ANG subdirectory, but the actual is 11 ATR images. In other words, the count is always one less than the actual. Does the count start from zero?).
There is a bug when searching the main CD folder (Pooldisk_Too_CD1). It always terminate at ATR image #234 of the ABBUC subfolder. Even though searching is always successful when ABBUC subfolder is being searched alone. The ATR image 173_B.ATR opens normally with Altirra without an issue.
