I know that two types of files(.trec, .tscproj) are made when I record computer screen by using camtasia 2018 program.
But I didn't know that a file(.trec) is necessary to run a file(.tscproj).
So I deleted many files(.trec) and then I clicked empty trash.
2. My current status
In order to recover the files, I purchased license of a program called "recovery my files".
As a result, I found many files(.trec) but there is a problem.
The problem is that file name is changed as strange name, such as "$IKRC525.trec".
Generally, my deleted file's name shows recording date and time, such as "REC 08 01 15.trec".
Furthermore, I recovered the files of strange name but they didn't play.
3. My Question
Can you tell me how to recover my files?
Deleted files are very important to write my thesis.
Please help me.
