How to Recover a Corrupt Flash Fileby Mike Smith
According to Microsoft, files usually become corrupted when something goes wrong just as a file is being saved. This could occur if your Flash editing program crashes or if your computer loses power while the save is in progress. Microsoft warns that corrupted files are usually difficult to restore, but there are several programs available online that can attempt to repair them.
Get Data's Recover My Files is a dual-purpose repair and recovery program (see Resources). Not only can it attempt to repair corrupted files of many types, including Flash, it can also recover accidentally deleted files. A download of the program comes with a free trial, but you will have to pay for a full version if you are attempting to repair large files. The repair process uses a simple, step-by-step interface that does not require advanced computer knowledge.
Download Virtual Lab by BinaryBiz if you need to attempt recovery of only a small file, because it comes with a free trial that allows you to recover one megabyte of information (see Resources). Further payment depends on the amount of data you need to recover. Simply provide Virtual Lab with information about the damaged file's location, wait for the program to generate a list of files it can attempt to restore, and then select your damaged Flash file from the list.
While it's not as easy to use as Recover My Files and Virtual Lab, Convar's PC Inspector File Recovery is worth a try since it is free to both download and use (see Resources).
