| 25 | 29 | ## Dependencies | |
| 26 | 30 | ||
| 27 | 31 | Small amounts of 386 assembler. | |
| 28 | 32 | ||
| 29 | 33 | ## Usage | |
| 30 | 34 | ||
| 31 | 35 | 1\. For your project open "Project-\>Compiler Options-\>Other unit files" and add the path to the FPArchive units | |
| 32 | 36 | ||
| 33 | 37 | 2\. In the "uses" clause of your unit add AbBase, AbBrowse, AbZBrows, AbUnzper, AbArcTyp | |
| 34 | 38 | ||
| 35 | 39 | 3\. Create an unzip object: | |
| 36 | 40 | ||
| 37 | 41 | ``` pascal | |
| 38 | 42 | UnZip := TAbUnZipper.Create(nil); | |
| 39 | 43 | ``` | |
| 40 | 44 | ||
| 41 | 45 | 4\. Set the directory where you want to extract the files to: | |
| 42 | 46 | ||
| 43 | 47 | ``` pascal | |
| 44 | 48 | UnZip.BaseDirectory := '/path/to/extract'; | |
| 45 | 49 | ``` | |
| 46 | 50 | ||
| 47 | 51 | 5\. To restore directories structure (optional) add this line: | |
| 48 | 52 | ||
| 49 | 53 | ``` pascal | |
| 50 | 54 | UnZip.ExtractOptions := [eoCreateDirs, eoRestorePath]; | |
| 51 | 55 | ``` | |
| 52 | 56 | ||
| 53 | 57 | 6\. Try to extract all CSV files (for example) from an archive file: | |
| 54 | 58 | ||
| 55 | 59 | ``` pascal | |
| 56 | 60 | try | |
| 57 | 61 | UnZip.FileName := '/file/to/extract.zip'; | |
| 58 | 62 | UnZip.ExtractFiles('*.csv'); | |
| 59 | 63 | except | |
| 60 | 64 | on E: Exception do | |
| 61 | 65 | begin | |
| 62 | 66 | //some error handling | |
| 63 | 67 | end; | |
| 64 | 68 | end; | |
| 65 | 69 | ``` | |
| 66 | 70 | ||
| 67 | 71 | 7\. Free the created object: | |
| 68 | 72 | ||
| 69 | 73 | ``` pascal | |
| 70 | 74 | UnZip.Free; | |
| 71 | 75 | ``` | |
| 72 | 76 | ||
