I'm trying to create some single files from individual files that were captured before a discussion forum went down. The topics I'm interested in have hundreds of individual files to be merged into one. I've uploaded a zipped example to https://mega.nz/file/z0hy3KxL#MbUvjDa-C7VWv_SGGARik0GMgrTCFoF0ovFr6gis5dY. If I merge 10 or 100 of these files, all is well. But if I merge all 251, files 9216-002.html through 9216-005.html are not placed in the proper order but are scattered throughout the file....
