FileSequence UDF My job requires me everyday to work with a LOT of file sequences, mostly image file sequences. So I created this UDF. I use it to batch convert image sequences to quicktimes, resize, rename, move, backup, count total frames ...etc... I use it for image scanning, but you can use it for any files numbered. Just type in the extention you need. In this UDF, I consider a file sequence to be of more than 3 consecutive files. Example: C:FolderImageSequence_001.tga C:FolderImageSequence_002.tga C:FolderImageSequence_003.tga .... --> C:FolderImageSequence_###.tga Example: If you scan this folder : "C:Folder", looking for extentions like "jpg tga mov", then the function may return an array like this: $array[0] = 3 $array[1] = C:FolderImageSequence_#####.tga $array[2] = C:FolderImageSequence_Converted_####.jpg $array[3] = C:FolderSubFolderquicktime movies ###.mov") You can convert the returned file sequence to format %0id or wildcard with the provided functions: C:FolderImageSequence_###.tga --> C:FolderImageSequence_%03d.tga --> C:FolderImageSequence_***.tga C:FolderImageSequence_######.tga --> C:FolderImageSequence_%06d.tga --> C:FolderImageSequence_******.tga This UDF is a relatively fast folder scanning UDF, scanning ~40 GB with about 100 file sequences (~5000 images) and gathering all the informations (Sequence length, Sequence Range, Dimensions, FileSize ...) takes about 6-7 seconds on my computer. Remark: parts of this UDF require IrfanView, which you can download for free on their website (www.irfanview.com). I am currently converting this part of the UDF to use the FreeImage UDF instead. The UDF also uses "Array.au3" and "GDIPlus.au3". Functions: _FileSequence_Convert (uses IrfanView) _FileSequence_Copy _FileSequence_Delete _FileSequence_Exists _FileSequence_Find (Main function) _FileSequence_FSToRegExp _FileSequence_FSToWildcard _FileSequence_GetFileName _FileSequence_GetImageDimensions _FileSequence_GetParentFolder _FileSequence_GetRange _FileSequence_GetSize _FileSequence_Move _FileSequence_Rename _FileSequence_Resize (uses IrfanView) If you see anything that could be improved, please tell me, I'd be happy to make it even faster! Comments and critics welcome! Tell me what you use it for, I am curious! File_Sequence.au3 File_Sequence_ExampleSimple.au3 File_Sequence_ExampleAdvanced.au3
